Get specified character or word from a string

The substr() function returns a part of a string.

Syntax: substr(string,start,length) where string and start is required. Length is a optional. This tutorial would help about a lot of string issue.

Example :

<?php  
   echo substr("Life is a beautiful", 9);       //beautiful  
   echo substr("Life is a beautiful", 3);       //e is a beautiful  
   echo substr("Life is a beautiful", -14, 2);       //is  
 ?>
