regex - PHP Regular expression to find string enclosed in __("STRING_TO

sorry suck @ regexp. need collect string on application enclosed in example: __("string") string may enclosed in single quote well.

i tried following code:

$str = "__('match1') __("match2") do_not_include __('match3')";  preg_match_all("/__\(['\"](.*)['\"]\)/", $str, $matches); var_dump($matches);

but able match entire line string 1 match. example result below. please me edit regexp should able 3 matches.

match1') __("match2") do_not_include __('match3

thanks in advance help.

you can use:

$str = "__('match1') __(\"match2\") do_not_include __('match3')"; preg_match_all('/__\(([\'"])(.*?)\1\)/', $str, $matches); print_r($matches[2]);

([\'"]) match either single or double quote , capture in group #1.

.*? match 0 or more characters (non-greedy)

\1 back-reference of above captured group make sure string closed same quote on rhs.

output:

array (     [0] => match1     [1] => match2     [2] => match3 )
