How Cake PHP Developer And Zend Developer Useful For Rapid Web Development

How Cake PHP Developer And Zend Developer Useful For Rapid Web Development

• The advantages of using Zend framework for PHP 5 development or even PHP Cake are that they are scalable over the long haul; it comes with a rather low maintenance cost.

• Hiring a Zend programmer or a Cake PHP expert covers all this but has the advantage of ensuring that whatever web development project you are undertaking is hastened on account of the following facts. Foremost the framework relies heavily on objective programming thus lowering the need for detailed code (this translates to saved time); secondly the two frameworks come with a rich inbuilt library which can be used for hybrid website development; and thirdly these frameworks have fluent interfaces that means they are highly compatible with a variety of software.
• Once you have gotten the above issue straightened out then the question that you need to answer is how exactly this two frameworks radically differ from other framework. It is important to note that web development will essentially encompass a few common denominators -the cornerstone that all web developments will always touch on include the following: reviewing the design and functional requirements for possible troubleshooting; a breakdown of the design pattern into panes; design a model that captures data as either a database records or in XML format. This is the bare minimum.
• If your are in the market for PHP 5 software, what you essentially need to first get is a Zend developer. Such a Zend programmer comes equipped with the technical know how on the issues that go along with laying down a Zend framework (an open source software framework for php 5 that is fashioned in such a manner that it eliminates the attention to detail required of coding, and lets the Zend programmer focus on the larger picture) .If you are in the market for Cake PHP - an open source web application program that aides a Cake PHP developer develop websites, then your best bet lies in hiring a Cake PHP expert. When you Hire a Cake PHP developer or hire a Cake PHP programmer, the following advantages (listed below) are set to accrue to you.
• Working in the field of web development has its own set of challenges. Key among these challenges is essentially how you get to tackle the bottleneck of time management. When you want to speedily set up a website what you essentially need to do is to fall back upon a re4liable web standard that mitigates against t constraints of time and other infrastructure overheads that might be presented to the web developer.

Using regular expressions to extract content - php extract texts from html content

Hello PHP Googler,

PHP provides a number of really neat regular expression functions. You can find the list of the regex function at the PHP site.

But the one that I’ve had most fun with is the preg_match_all() function which I’ve been using to do content extraction from an HTML page.

I’m not going to explain what Regular Expression (regex) is in this post. There are whole books on just this one topic along; I would be crazy to think I can explain it all in just a few paragraphs. But in order for you to understand how to use the regex functions you need to have a basic understanding of regular expressions.

If you think back to your childhood days, you would remember a toy that you can match holes with shapes with the corresponding blocks – like the picture here. Well, regular expressions is very much like that toy, but instead you have define your own ’shape’ (or pattern as it’s known) and apply your content to it. Any text that matches the pattern will ‘fall’ through it.

Let’s say you have a block of text like below and you want to extract out the all links from, you can use preg_match_all to do just that.

 
$content = "He's goin' everywhere, <a href=\"http://www.bjmckay.com\">B.J. McKay</a> and his best friend Bear. Rollin' down to <a href=\"http://www.dallas.net\">Dallas</a>, who's providin' my palace, off to New Orleans or who knows where." 
The pattern you want to look for would be the link anchor pattern, like <a href=”(something)”>(something)</a>. 
The actual regular expression might look something like Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this
$regex_pattern = "/<a href=\"(.*)\">(.*)<\/a>/";

Once you have your pattern you apply the $content and $regex_pattern to preg_match_all() like this
preg_match_all($regex_pattern,$content,$matches); print_r($matches);
preg_match_all will store all the matches into the array $matches, so if you output the array,
you’ll see something like this.

Array ( [0] => Array ( [0] => <a href="http://www.bjmckay.com">B.J. McKay</a> [1] => <a href="http://www.dallas.net">Dallas</a> ) [1] => Array ( [0] => http://www.bjmckay.com [1] => http://www.dallas.net ) [2] => Array ( [0] => B.J. McKay [1] => Dallas ) )



From this array, $matches, you should be able to loop through and get the information you need.

I hope this has been useful to you. I know it doesn’t cover all the things this function can do, but for first-timers, it should be a simple look at a very powerful PHP function.

Incidently, PHP also provides the function preg_match(). The difference is preg_match() only matches a single instance of the pattern, whereas preg_match_all() tries to find all matching instances within the content.

Hardening Your Web Application Against SQL Injections

Hi All,


Before digging what actually SQL Injection is, let me explain you what is SQL it self.
What is SQL?


Structured Query Language (SQL) is a specialized programming language for sending queries to databases. Most small and industrial- strength database applications can be accessed using SQL statements. SQL is both an ANSI and an ISO standard. However, many database products supporting SQL do so with proprietary extensions to the standard language. Web applications may use user-supplied input to create custom SQL statements for dynamic web page requests.


What is SQL Injection?


SQL injection is a technique that exploits a security vulnerability occurring in the database layer of a web application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed. It is in fact an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another.
“SQL Injection” is subset of the unverified/unsanitized user input vulnerability (“buffer overflows” are a different subset), and the idea is to convince the application to run SQL code that was not intended. If the application is creating SQL strings naively on the fly and then running them, it’s straightforward to create some real surprises.


Many organization’s web servers has been compromised just because of SQL Injections, including big names which I would not like to mention here, you can search it easily on Internet.


What is Blind SQL Injection?
This particular type of attack is called a blind SQL injection attack, because the attacker cannot take advantage of detailed error messages from the server or other sources of information about the application. Getting the SQL syntax right is usually the trickiest part of the blind SQL injection process and may require a lot of trial and error. But, by adding more conditions to the SQL statement and evaluating the Web application’s output, an attacker will eventually determine whether the application is vulnerable to SQL injection.


Blind SQL injection a special case that plays on the web developers or website owners sense of security. While they may think that everything on the server is tightly guarded a Blind SQL injection attack will silently be playing truth or consequences with the web server. This type of attack though very time consuming is one that provides the most potentially damaging security hole. This is because an attacker gets not only access but is provided with an enormous amount of knowledge about the database and can potentially gain access to a servers file system. This type of attack is one that is automated and requires good amount of setup to succeed. But once it is done it does not require a great deal of effort to repeat.
What is Error message SQL Injection?


Web applications commonly use SQL queries with client-supplied input in the WHERE clause to retrieve data from a database. When a Web application executes such queries without validating or scanning the user-supplied data to ensure it’s not harmful, a SQL injection attack can occur. By sending unexpected data, an attacker can generate and submit SQL queries to a web applications database. A test for SQL injection vulnerabilities takes place by sending the application data that generates an invalid SQL query. If the server returns an error message, that information can be used to try to gain uncontrolled access to the database. This is the basis of one of the most popular SQL injection attacks.
Hiding error messages does not stop the SQL injection attack. What typically happens is the attacker will use the knowledge gained from the failure of this attack to change tactics. What they turn to is blind SQL injection.


What is SQL Injection?

When a web application fails to properly sanitize user-supplied input, it is possible for an attacker to alter the construction of backend SQL statements. When an attacker is able to modify a SQL statement, the process will run with the same permissions as the component that executed the command. (E.g. Database server, Web application server, Web server, etc.). The impact of this attack can allow attackers to gain total control of the database or even execute commands on the system.

What has been a long interest of mine in writing simple, maintainable and secure (a.k.a. Good[tm]) code, has forked off the offspring of optimization.

There are nummerous discussions in the blogosphere about whether to use echo versus print, iffor() is faster than while(), etc. and though the gains are usually very small, I desided to add my thoughts to the debate.

I found an article on optimization through coding habits in Ilia Alshanetsky's zend performance slides and decided to test some of the claims. My test machine is my MacBook Pro 1.83GHz w. 2GB RAM, MacOS X 10.4.9, Apache 1.3 and PHP 5.2 (with Xdebug 2.0). I also have lots of applications running.

• Peter Bowyer claims that require_once() is 3-4 times slower than require(). Ilia also says they are bad. My testing reveals the exact opposite with an empty include file. Callingrequire_once() 10000 times in a for() loop with an empty file is 4x faster.
• Ilia advises against using magic functions like __autoload() and __get(), but the advantage of __autoload() in particular is obvious in any large project and is used by many phpframeworks. My primitive testing, however, shows inverse results. With a simply autoload requiring a class and 10000 loops of new Foo() versus require_once('foo.php'); new Foo() shows that __autoload() is ~3.7 times faster. I saw no difference between real methods and __get(), although the logic inside __get() will add some overhead.
• If a class method can be static, declare it static. Speed improvement is by a factor of 4. I get a 50% speed increase (614ms vs. 414ms with 100000 iterations).
• Avoid function calls within for() loop control blocks. In for( $i=0; $i<count($x); $i++ )the count($x) is called at every iteration.
• Always, always quote array keys. $row['id'] is way faster than $row[id]. Ilia says 700%, I say about 200%.
• Avoid regex if possible. Use ctype_digit($foo); rather than preg_match("![0-9]+!", $foo);.
• Get rid of 'harmless' error messages - they take time to generate and output. The error supression operator @ is slow, so avoid when possible. With error_reporting set to E_ALL | E_STRICT on my machine, doing echo $rows[id] 10000 times instead of echo $rows['id]takes 38 times longer.
  
  UPDATE: To summarize, this slow code runs in 500ms (although this time will vary a great deal depending on your error_reporting level):
  
  
  
  
  
  
  
  $rows = array_fill(0, 10000, array('id'=>0));
  require_once('foo.php');
  for( $i=0; $i < count($rows); $i++) {
  foo::notdeclaredstatic();
  
  $rows[$i][id] = 0;
  }
  
  
  

  By using the techniques above, it can be made to complete in 68ms:

  $rows = array_fill(0, 10000, array('id'=>0));
  function __autoload($classname) { require_once( 'foo.php'); }
  $size = count($rows);
  for( $i=0; $i < $size; $i++) {
      foo::declaredstatic();
  
      $rows[$i]['id'] = 0;
  }

  10000 iterations is a lot for one request to a page. Using the techniques, the code became roughly 7 times faster.
  
  I am not out to prove Ilia wrong - he knows PHP better than most - and 

  for all I know, they could have optimized those very functions in PHP 5.2. I am, however, 

  interested in seeing what can be done to optimize PHP performance simply by doing things differently,

  by tweaking one's coding style. It would appear that there are improvements, albeit small, to achieve 

  from minimal effort. Plus I was surprised by the discrepancies I found compared to Ilia's recommendations.

  Hope this post helped you.

Timezones in MySQL and PHP

Hay Googler,


Timezones in web applications are often dealt with the same way as character sets. Either incorrectly or ignored. The case of unicode is improving slowly as developers discover the need for international language support.


The problem with not handling timezones correctly is not apparent in the usual case of the webserver and the database server being in the same timezone. A lot of PHP code passes the task of timestamps on to MySQL, e.g. by calling NOW() on inserting or updating records. It is nessesary to know in what timezone the timestamps are stored to process them correctly.
Often a specific timezone is assumed for displaying date and time. This could very well be incorrect for a large number of visitors. If the database server is in yet another timezone, things begin to get out of sync.
MySQL's handling of timezones is - obviously - separate from that of PHP. Along with the fact that the MySQL timezone can only be changed by users with SUPER privileges, this means that MySQL cannot be relied on for creation of timestamps in correct timezone. In other words, the usual call toNOW() is not an option.
PHP 5.1 introduced the date_default_timezone_set() method for setting the timezone PHP will use for functions like date() (or alternatively the date.timezone php.ini directive). This allows for a flexible and consistent way of creating timestamps in the correct timezone form within PHP. One user in London might start a thread while a response comes from New York. To handle this consistently and make sure both users see local time and the correct timespan between the posts, use date_default_timezone_set() to create the timestamps from PHP in a fixed timezone like GMT.
Time for an example to illustrate the practical use of this. I created a simple class Timer for dealing with these operations. The methods will be called statically as there is no need to instantiate the class.


---------------------------------------------------------------------------------------

class Timer 
{   
    static function DatetimeInGMT() {
        return date("Y-m-d H:i:s", time()-date("Z",time()));
    }

    static function GMTDatetimeToLocal($datetime) {
        $time = strtotime($datetime);
        return date("Y-m-d H:i:s", $time+date("Z",$time));
    }
}
--------------------------------------------------------------------------------------------------------------------------------

Timer::DatetimeInGMT() produces a timestamp in GMT. I use it instead of MySQL's NOW()because it calculates the time relative to the timezone set in PHP rather than that of MySQL.



When reading the timestamp back in to PHP, another function call is needed to convert it back to whatever timezone PHP is in at that time (it might be a different user viewing with another timezone setting). That's the job of Timer::GMTDatetimeToLocal($datetime).
These two very simple functions and a correct setting of PHP's timezone will ensure that dates are stored in a consistent way and displayed correctly.
