PHP parser - like the ones on here

[newmand2]

I am wondering how easy/hard it is to create a parser, where you can insert PHP into a textarea and on the output page it will colour PHP accordingly. Like the one on this forum. Is it a server installation? Downloadable code? Thanks

<?php
$str = '<?php echo "la de la"; ?>';
$str = highlight_string($str);
echo $str;
?>

Give that a bash

Thank you! Unless its real inconvenient, What about doing one where you can use [-P-H-P-]Without the hyphens[-/-P-H-P-]?

Or will that do it

You'd need to use regex to do that, I'm not good at it but will see if this works for you

<?php

$str = '[ php]<?php echo "la de la"; ?>[/ php]';

$str = preg_replace("/^[php](.*?)[/\php]/$",highlight_string(\\1),$str);

echo $str;

?>

It might work, be lucky if it did lol

OK, thanks alot, tbh it doesnt look like it will work but ill build from it

You wanna get mordred's attention to here, he's like the a-team of regex.

im not great myself, but try:

<?php

$str = '[[b][/b]php]<?php echo "la de la"; ?>[/[b][/b]php]';

$str = preg_replace("/\\[php\\](.*)[\\/php\\]/ise", highlight_string("$1"), $str);

echo $str;

?>
