Code

(preg_match_all("#\[level-(.+)-\](.+?)\[/level\]#", $string, $matches)

Problem

if I assign any value to $string with enter, my regex doesn’t work.

Example:

//This doesn't work
$string = '[level-0-]This is a 
test[/level]';
//This works
$string = '[level-0-]This is a test[/level]';

What I Want

I would like my regex to work no matter what characters between (enter, etc..).

I will be glad if anyone could help me out with this one. I still didn’t dig into regex yet so I’m not that good with it 🙁

    You just need the DOTALL flag /s in your regex. This allows the dot . to match any character, including linebreaks (which it doesn’t do per default).

    preg_match_all("#\[level-(.+)-\](.+?)\[/level\]#s", ....
