Simple PHP Exception Handling explanation

What is an Exception

Finaly, with php5 came a new object oriented way for dealing errors,
if a specified error (exceptional) condition occurs exception handling is used to change the
flow of the code execution .

Exceptions are a great tool and should only be used with error conditions,
dont ever use them to jump to another place in the code at a specified
point - you cant know what will happend.

Basic Use of php5 Exceptions

When an exception is thrown, PHP will try to find the matching “catch” block.

The bad way:

<?php
 function checksum($number1=NULL,$number2=NULL)
   {
       if($number1===NULL OR $number2===NULL)
          {
  throw new Exception("Value must not be NULL");
 }
   return true;
  }
 checksum(7,NULL);
 ?>

The good way:

<?php  function checksum($number1=NULL,$number2=NULL)   {      if($number1===NULL OR $number2===NULL)      {    throw new Exception(”Value must not be NULL”);      }      return true;      }     try      {     checksum(4,NULL);     //If the exception is thrown, you will not see the text     echo ‘If you can see this message,    the numbers you send to the checksum function are valid;     }    //catching the  exception catch(Exception $e)    {     echo ‘Message: ‘ .$e->getMessage();      }  ?>

Good Luck! use this php5 tool smartly.

PHP Easter Egg / 1 April

Well, it just so happens that if you add this string :
?=PHPE9568F36-D428-11d2-A769-00AA001ACF42
at the end of any URL that is a PHP page (www.somewebsite.com/somephppage.php?=PHPE9568F36-D428-11d2-A769-0z0AA001ACF42) you will see a funny little picture of a dog.
for every version of PHP there is a difference image
