Getting Value Inside Bracket Using preg_match Function

First we need to compose and declare some pattern.

$pattern = "/(\\(\\')(\\s*.*)(\\'\\))/";

Then using `preg_replace` function we can get the value inside bracket on array return. Below is the full code example.

$pattern = "/(\\(\\')(\\s*.*)(\\'\\))/"; 
$value = "foo('bar')";
preg_match($pattern, $value, $matches); 
$result = $matches[2];
