php - Find a percentage value in a string using preg_match -

-

i'm trying isolate percentage value in string of text. should pretty easy using preg_match, because percentage sign used operator in preg_match can't find sample code searching.

$string = 'i want 10%  out of string';

what want end is:

$percentage = '10%';

my guess i'll need like:

$percentage_match = preg_match("/[0-99]%/", $string);

i'm sure there quick answer this, solution evading me!

if (preg_match("/[0-9]+%/", $string, $matches)) {     $percentage = $matches[0];     echo $percentage; }
