Pattern replacing?

Dean

In all the time I've known PHP, I've never been able to make pattern matching work!

All I need to know is how to take code such as " [ b ] text [ /b ]" (minus the spaces)

and convert it to text

thanks!

$yourstring = str_replace("[ b ]","",$yourstring);
$yourstring = str_replace("[ /b ]","",$yourstring);

that works, but I need to make sure that there is a trailing [ /b ], or else the user could make the entire page bold

Maybe

$str = preg_replace('/ b [ /b ]/', '$1', $str);

I'd use ungreedy matching here, else everything from the first opening to the last closing tag will get bold in case there are more than one pair of tags. and don't forget to escape the slash in the pattern, or use different delimiters.

$str = preg_replace('# b [ /b ]#i', '$1', $str);

So you want to guess at where the user wants the end-bold tag? Forgive me for saying, but you can't prevent people from being stupid.
