PHP RegEx: Match A String PHP Script
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.
