In this tutorial I will show you the basic in regex. In brief discussion. Regex is considered a method of matching pattern within a string. In PHP usually used PCRE or "Perl Compatible Regular Expressions". Let's see a sample to print a string.

<?php
 
// create a string 
$string = 'abcdefghijklmnopqrstuvwxyz0123456789'; 
// echo our string 
echo $string; 
 
?>

The above code are printing "abcdefghijklmnopqrstuvwxyz0123456789". Now were going to match the character "xyz" using regex.

<?php 
 
// create a string 
$string = 'abcdefghijklmnopqrstuvwxyz0123456789';
echo preg_match("/xyz/", $string);
 
?>

The code above will output "1" because the character "xyz" are matches to the string given. Then the preg_match will output zero "0" if it could not matches to the string given.
