Unknown modifier ” error preg_match

Running this error while adopting preg_mathc in php? Just check if the delimiters are not used in your string – mostly this would fix the problem.

$example = "<root><tag1>content1</tag1></root>";
$pattern = "/<tag1>.+</tag1>/";
preg_match($pattern, $example, $matches) ; 

If you run the above snippet, you would run the error as the delimiter ‘/’ is the part of the string – so changing the delimiter, say, to ‘?’ would solve the problem. like

 $pattern = "?<tag1>.+</tag1>?

Hope it would help.
