var_dump($match1);
var_dump(preg_match('/l^o,\s\w{5}/', $string, $match2, PREG_OFFSET_CAPTURE)); // tries to find "lo, world" at start of string
var_dump($match2);
var_dump(preg_match('/\[\*\],\s(.*)/', $string, $match3)); //finds "[*], this is \ a string";
var_dump($match3);
var_dump(preg_match('@\w{4}\s\w{2}\s\\\(?:\s.*)@', $string, $match4, PREG_OFFSET_CAPTURE, 14)); //finds "this is \ a string" (with non-capturing parentheses)
var_dump($match4);
var_dump(preg_match('/hello world/', $string, $match5)); //tries to find "hello world" (should be Hello, world)
