Erm, its been tested?

Ok, so the one I posted doesn't work if you do not include <?php ?> tags.

It was just something I knocked up, quickly tested and posted. I'm sure someone could implement something that would check for them, and if not include them.

works now

Code:

echo preg_replace("/(?:\[php\])[\r\n]*(.*)(?:\[\/php\])/esi", "parsePHP('\\1')", $string);

function parsePHP ( $php )
{
return ("<?" == substr( $php, 0, 2)) ? highlight_string( $php, TRUE )
: highlight_string("<?php ". $php ." ?>", TRUE );
}

My above 'bug' fixed.

well, i'll proably end up using regex, but I though using str posisions was so cool!

*adds my input*

NOTE: I'm NOT claiming this to be my code, while i DO understand it and know how it works, i did NOT write it myself, not this time around anyways... open source is handy

Code:

function bbcode($str){
$str = preg_replace("/(\[)(php)(])(\r\n)*(.*)(\[\/php\])/esiU", "phphighlite('\\5')", $str);
return $str;
}

// Start phphighlite
function phphighlite($code) {
//PHP 4 only

if (floor(phpversion())<4) {
$buffer=$code;
} else {
$code = str_replace("<br>", "", $code);
$code = str_replace("<br />", "", $code);
$code = str_replace(">", ">", $code);
$code = str_replace("<", "<", $code);

$code = str_replace("&", "&", $code);
$code = str_replace('$', '\$', $code);
$code = str_replace('\n', '\\\\n', $code);
$code = str_replace('\r', '\\\\r', $code);
$code = str_replace('\t', '\\\\t', $code);

$code = stripslashes($code);

if (!strpos($code,"<?") and substr($code,0,2)!="<?") {
$code="<?".trim($code)."?>";
$addedtags=1;
}
ob_start();
$oldlevel=error_reporting(0);
highlight_string($code);
error_reporting($oldlevel);
$buffer = ob_get_contents();
ob_end_clean();
if ($addedtags) {
$openingpos = strpos($buffer,'<?');
$closingpos = strrpos($buffer, '?');
$buffer=substr($buffer, 0, $openingpos).substr($buffer, $openingpos+5, $closingpos-($openingpos+5)).substr($buffer, $closingpos+5);
}
$buffer = str_replace(""", "\"", $buffer);
}

return "$buffer";
}

the returned value of the phphighlight function is just the text highlighted... you can format it how you like. e.g.

php:<hr>$buffer<hr>

hope this helps someone

return "$buffer";
}

vB uses very unefficient regex's

Also, that doesn't make use of the highlight_string() functions alternative return type, but uses output buffering to capture the string.

yeh, i have to say i wouldn't write the regex like that, but then i can't remember much regex offhand *sigh* as for ob, i would use that as opposed to the return true option too... just preference i guess

i looked into the highlight function from phpBB board , i can olny say .

Well, I've been intrested in this issue and came across an error with Recessive's regular expression. For some reason when I did this:

Code:

{PHP]
<?php
print 'hi';
?>
{/PHP]

{PHP]
<?php
$str = 'hi';
?>
{/PHP]

(the { are [)

It would ignore the end of the first php block and the start of the second. So it would display what's between the start of the first and the end of the second. So here's what I did to get it fixed: (this is off of Recessive's first example, but can be easily transformed to his 'bug' fix)

Code:

$str = preg_replace("/(\[PHP\])[\r\n]*(.*?)(\[\/PHP\])/esi", "highlight_string('\\2',true)", $str);
