PHP Syntax highlighting

Mew151

I'm making a PHP bbcode for some blog software I'm making, and I'm trying to do this:

if(eregi("\[php\](.*|\n)\[/php\]", $content))
{
	$content = eregi_replace("\[php\](.*|\n)\[/php\]", highlight_string(html_entity_decode("\\1", ENT_QUOTES), true), $content);
}

However entities aren't being decoded and no syntax highlighting is taking place. (Though it does wrap a code tag around it.)

This is the input I have:

[php[i][/i]][b]&lt;[/b]?php
echo "Hello, world!";
?[b]&gt;[/b]

[/CODE]

Can anyone tell me what's wrong?

You should check the manual on all the [man]eregi[/man] functions. It says, "This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged." So you may want to rethink your approach all together. And if you are using PHP 5.3.0 that could possibly explain the problem.

Ignore this post misread your code

The function works perfectly, and I even changed it to preg_match and preg_replace now, but the string is not being html_entity_decoded or string_highligted.

This seems to work. (Note that I added spaces in the PHP bbcode tags within the code so the form would not get confused. You need to remove them to make it work.)

<?php
$content = 'This is not code.
[ php]&lt;?php  // added space here so would display OK on forum
if(true) {
   $test = "This is a test.";
   echo $test;
}
?&gt;[ /php] // added space here so would display OK on forum
This is not code, either.';

$content = preg_replace_callback(
   '#\[php\](.*?)\[/php\]#is',
   create_function(
      '$matches',
      'return "<br />" . highlight_string(html_entity_decode("$matches[1]"), true) .
         "<br />";'
   ),
   $content
);

echo $content;
