irregular bbcode

[sushestvo]

I Have regexp replacements in order to have working bbcode on the site.
But I also want to include new tag [no][/no] which will remove any codes inside of itself (ie write them as text). It's easy in theory - just to grab everything inside NO tag and replace all "[" and "]" to their html codes (ie [ and ]).
Anyone can help me in practice here plz?
It doesn't have to be a regexp, i can do replacement b4 everything else, cuz regexp may actually slow down performance in this case.

PHP Code:

$string = '';
$search = array('[', ']');
$replace = array('', ''); // put in html codes
preg_replace('/\[no\](.*?)\[\/no\]/is', str_replace($search, $replace, '$1', $string); 


ok try that... not sure though

[sushestvo]

i appreciate your reply, at least someone =)
That's what I've inserted b4 my code

$searchforno = array('[', ']');
$replaceforno = array('[', ']');
$string = preg_replace('/\[no\](.*?)\[\/no\]/is', str_replace($searchforno, $replaceforno, '$1', $string));

Unfortunatly, now it won't output anything at all though.

anyone else can help maybe?

$string = '';
$search = array('[', ']');
$replace = array('', ''); // put in html codes
echo preg_replace('/\[no\](.*?)\[\/no\]/is', str_replace($search, $replace, '$1'), $string);

That shouldn't work as str_replace() will be executed before the preg_replace.

[sushestvo]

yeah it didn't really do anything

how will it work though

[Mwnciau]

hmmm

PHP Code:

while (preg_match('/\[no\].*?\].*?\[\/no\]/is', $string)){
$string = preg_replace('/\([no\].*?)\](.*?\[\/no\])/is', '$1 ]$2', $string);
}
while (preg_match('/\[no\].*?\[.*?\[\/no\]/is', $string)){
$string = preg_replace('/\([no\].*?)\[(.*?\[\/no\])/is', '$1[ $2', $string);
} 


Maybe that will do the trick (hopefully).

PHP Code:

preg_replace_callback('/\[no\].*?\].*?\[\/no\]/is', create_function('$matches', 'return str_replace($search, $replace, $matches[0]);'), $string); 


[sushestvo]

have another function worked. With preg_replace_callback.
Thanks all =)
