[RESOLVED] replacing specific numbers of a character

[steamPunk]

Hi

I'm trying to make a simple text formatting thing using curly brackets where

{ text } = bold
{{ text }} = italic

etc

so i'm using this to replace the brackets in the text

	
$str = preg_replace('/\{/', '<span class="bold">', $str);
$str = preg_replace('/\}/', '</span>', $str);

the problem is that with a double bracket it replaces each one twice :

<span class="bold"><span class="bold">text</span></span>

so i ended up putting them in reverse order so that 3 brackets are replaced first, then two, then one

that works fine but i'd be interested to know what I would need to do to make it count the number of brackets before doing the replacing ?

thanks

preg_replace('/\{{1}/', '<span class="bold">', $str); 

preg_replace('/\{{2}/', '<span class="bold">', $str); 

preg_replace('/\{{3}/', '<span class="bold">', $str); 

The {X} means X many characters. {x,X} means between x and X characters.

X is obviously an integer.

ok, that's neat and elegant !

thanks for that 🙂
