Extract PHP code

[The Little Guy]

I have user comments on my site, and the user can post php in there comments.

 

Like this:

This is a test with PHP

<?php

echo ''hello test'';

?>

 

How would I extract the PHP, and place it in the highlight_string function, and leave the rest alone?

I found this way to work (I think) is it a good way or is there a better one?

 

$comment = preg_split("/^(<\?php.*?\?>)/ms", $cow['comment'], -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
foreach($comment as $line){
preg_match('/<\?php/s', $line, $matches);
if($matches[0]){
	highlight_string($line);
}else{
	echo $line;
}
}

Hmm, the above isn't amazing...

 

If I do this:

This is a test, with PHP

<?php

echo 'hello test';

?>

No php here

<?php

echo 'hello test';

$blue = '?>';

?>

 

the value for variable $blue, the parser thinks that that is where I want to stop, which it isn't so that is one bug...

just read the notes in the manual for highlight_string() there's a ton of entries doing exactly what you want.
