What is meant by Exceptional Handling?

Exceptions PHP 5 has an exception model similar to that of other programming languages. An exception can be thrown, try and caught within PHP. A Try block must include at least one catch block. Multiple catch blocks can be used to catch different class types; execution will continue after that last catch block defined in sequence. Exceptions can be thrown within catch blocks. When an exception is thrown, code following the statement will not be executed and PHP will attempt to find the first matching catch block.
