preg_match check if string is surrounded in double or single quotes

Question

Can someone tell me the regex to see if something is surrounded in double or single quotes.

"this is the string"

i want it to return false if it quotes are not present at all or not present at the start and the end.

Answer 1

preg_match('/^(["\']).*\1$/m', $string);

will return 1 if the string is surrounded by double quotes and 0 if it is not.
