PHP Regex and enter problem

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 = '[l开发者_开发问答evel-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", ....

See also the PCRE flags list http://php.net/manual/en/reference.pcre.pattern.modifiers.php

You probably need to get regex to treat its input as a single line by adding the /s flag to your pattern.

Use s Pattern Modifier:

If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are excluded. (Ref: Possible modifiers in regex patterns)

this should work :

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

"Test[.|\n]is[.|\n]a[.|\n]test" this might work
