How To Take a Substring from a Given String?

If you know the position of a substring in a given string, you can take the substring out by the substr() function. Here is a PHP script on how to use substr():

<?php
$string = "beginning";
print("Position counted from left: ".substr($string,0,5)."\n");
print("Position counted form right: ".substr($string,-7,3)."\n");
?>

This script will print:

Position counted from left: begin
Position counted form right: gin

substr() can take negative starting position counted from the end of the string.
