获取两个字符串php之间的子字符串

Question

suppose i have a set of strings formatted in a way:

$string1 = "(substring1) Hello";
$string2 = "(substring2) Hi";

how do i get the inside of '()' as a single string. I know this is possible by using:

$substring = explode( ")",$string1 );

but then i'm left with $substring[0] containing "(substring", and $substring[1] containing the rest. Is there a fast wat to get the inside of '()'? thanks i know it's a no brainer question.

Answer 1

explode might need a workaround because ( and ) are different. A simple regex will get the job done.

$string1 = "(substring1) Hello";
preg_match('#\((.*?)\)#', $string1, $match);  // preg_match_all if there can be multiple such substrings
print $match[1];
