PHP BBCode style code conversion using regex
So I have a tag like [code style=php]<?php echo "Hello world!"; ?>[/code]
A user may use plenty of those tags in a textarea so开发者_开发知识库 what I want to search for is [code style=(.*)]text[/code] so if the style is PHP for example I want to do highlight the code inside the tags and so on with other languages.
Why reinvent the wheel. Stackoverflow already has answer for this: PHP syntax highlighting
UPDATE
After reading comment. You can convert it like this:
<?php
function parseContent( $string )
{
$search = '/\[code style="(.*?)"\](.*?)\[\/code\]/is';
preg_match_all($search, $string, $output);
foreach( $output[ 0 ] as $idx => $raw_html)
{
$style = $output[ 1 ][ $idx ];
$content = $output[ 2 ][ $idx ];
$new_html = "<div class='codetext' id='$style'>$content</div>";
$string = str_replace($raw_html, $new_html, $string);
}
return $string;
}
?>
Here's some test code:
<?php
$string = <<<EOM
some pre content
[code style="php"]
<?php
echo "this is PHP";
?>
[/code]
some content in the middle
[code style="html"]
<body>
<h1>TITLE IS HERE!</h1>
</body>
[/code]
another content after content
EOM;
$string = parseContent( $string );
?>
