| ## Substring Function in PHP
 | |
| 
 | |
| The Substring function in PHP returns a portion of the string, specified by two parameters, the start and the length.
 | |
| 
 | |
| 
 | |
| ## Syntax
 | |
| 
 | |
| The substring function is used like any other function in php, and uses the subtr() syntax.
 | |
| 
 | |
| 
 | |
| ```
 | |
| <?php
 | |
| 
 | |
| subtr( $string, $start, $length);
 | |
| 
 | |
| 
 | |
| ```
 | |
| 
 | |
| 
 | |
| ## Example
 | |
| 
 | |
| Below is an example of how you could use the substring function in a real world situation:
 | |
| 
 | |
| ```
 | |
| <?php
 | |
| 
 | |
| $apple = 'Apple';
 | |
| $alphabet = 'abcdefghijklmnopqrstuvwxyz';
 | |
| 
 | |
| substr($apple, 0, 5);  				// Apple;
 | |
| substr($apple, 0, 3);  				// App;
 | |
| substr($apple, 3, 2);  				// le;
 | |
| substr($alphabet, 0, 26);  			// abcdefghijklmnopqrstuvwxyz;
 | |
| substr($alphabet, 12, 6);  			// mnopqr;
 | |
| 
 | |
| ```
 | |
