I have a string in PHP for example $string = "Blabla [word]";
I would like to filter the word between the '[' brackets.
The result should be like this $substring = "word";
thanks

preg_match('/\[(.*?)\]/', $string, $match);
$substring = $match[1];

@binary: in case there are many such substrings, you'd want to capture them individually I suppose.

If there are many such substrings, I would use
preg_match_all() with 'U' modifier (PCRE_UNGREEDY) instead of preg_match(). I can't get though, why do ".*?" and ".*" return different results with strings like "foo [bar] something [else]"SilentGhost
@binary:
.*? is a lazy quantifier, the same what 'U' flag does: Matches pattern of any length but prefers the shortest one.binaryLV
@SilentGhost: didn't know about such usage of
?, tx for explanationTry:
preg_match ('/\[(.*)\]$/', $string, $matches);
$substring = $matches[1];
var_dump ($substring);
