A small regex tool

[bugsquat]

Could somebody help me come up with some code that scans a given string for uppercase BBCode, and converts it to lowercase?

i.e.

$data="[SOMETHING]I am a Banana![SOMETHING]"
taglower($data)="[something]I am a Banana![/something]"

or

$data="[GLECK=48]Mosquitoes make good muffins![/GLECK]"
taglower($data)="[gleck=48]Mosquitoes make good muffins![/gleck]"

See if this does the trick:

$data = preg_replace('/\[([^\]]+)\]/e', '"[".strtolower(\\1)."]"', $data);

[bugsquat]

<?php

$data = "[BEE]eee with me[/BEE]";

function taglower($data){
$data = preg_replace('/\[([^\]]+)\]/e', '"[".strtolower(\\1)."]"', $data);
return $data;
}

echo taglower($data);

?>

Parse error: syntax error, unexpected '/', expecting ')' in /nfsn/content/pulsoid/public/test/bb/taglower.php(6) : regexp code on line 1

Fatal error: preg_replace() [<a href='function.preg-replace'>function.preg-replace</a>]: Failed evaluating code: &quot;[&quot;.strtolower(/BEE).&quot;]&quot; in /nfsn/content/pulsoid/public/test/bb/taglower.php on line 6

I would say...

$data = preg_replace('/\[([^\]]+)\]/e', '"[".strtolower("\\1")."]"', $data);

Thank you much. Works flawlessly (so far).

Thanks, not the first time I forgot the quotes in that situation. :rolleyes:
