[RESOLVED] Help please :: RegEx replace using preg_replace()

[aalcantara]

I need to replace file extensions that are not equal to .php using preg_replace()

Let's say I have the following strings to be replaced:

form.c
library.h
module.php
index.html
common.inc
data
helpers.inc.bak

basically, I need to replace all of the strings where the extension is not equal to .php and change the extension to .php
example expected result:
form.c becomes form.php
library.h > library.php
module.php > module.php (stays the same)
index.html > index.php
common.inc > common.php
data > data (stays the same since there is no extension to replace)
helpers.inc.bak > helpers.inc.php

Let me know if you need more info. Thanks in advance.

hi,

My regexp skills are not up to scratch to help you with that. But.. If you just need to do this once of (e.g. changing include files bacuase you changed your backend) you could use a packages like notepad++ which has a find-and-replace in files functionality..

Thanks, although I do really need to know how to do a preg_replace() on something like this. The example I have provided is just for the purpose of giving example to regex experts out there to understand what I like to achieve.

I like to know, how to achieve this kind of situation. Help please.

Consider this example:

<?php
$filenames = array(
    'form.c',
    'library.h',
    'module.php',
    'index.html',
    'common.inc',
    'data',
    'helpers.inc.bak');

foreach ($filenames as $filename) {
    echo preg_replace('/^(.*)\..*$/', '$1.php', $filename) . '<br />';
}
?>

Awesome, thanks.
