str_replace

[supanoob]

basically i have a forum system. the system used codes such as:

 

[b][/b] for bold
[u][/u] for underline
[url=*url*]Link name[/url] to link

 

Now the problem i have is when i replace all those [ and ] for < and > if someone types a normal [ or ] without it being linked to that code it turns it into a < or >.

 

Now i know how to fix it for most things, but when it comes to the one i cant think of a way to get the closed bracket onto it. Any idea?

i would use preg_match to match the entire thing and pick it apart.

 

Something like

 

$url = '[url=http://www.phpfreaks.com/forums/index.php?action=post;topic=205723.0;num_replies=0]Link Title[url]';

preg_match("/\[url=(.*?)](.*?)\[url\]/",$url,$matches);


print_r($matches);

 

 

gives

 

Array
(
    [0] => [url=http://www.phpfreaks.com/forums/index.php?action=post;topic=205723.0;num_replies=0]Link Title[url]
    [1] => http://www.phpfreaks.com/forums/index.php?action=post;topic=205723.0;num_replies=0
    [2] => Link Title
)

yes if i do that ima still have the problem of [ becomeing < etc because im still going to have to convert them.

so you use preg_match to get the parts, build a real hyperlink from them, then use a normal str_replace to replace the entire string with the new one.
