How to match all "types" and escape the regex properly?

Question

I am currently struggling to match the content of following "Types":

(Type): multiplechoice
(Category): 0
(Random answers): 0
(Question): Which of the following is true about pre-test imagery?

(Type): multiplechoice
(Category): 0
(Random answers): 1
(Question): Which of the following is not true about the TMJ?

I am trying:

preg_match_all("(Type)\:(.+?)\n", $content, $types);

But I get an unknown modifier "\" as an error message.

How can I properly match all the types? Thanks for any hints!

You need to use delimiters in PHP with regexs. http://php.net/manual/en/regexp.reference.delimiters.php You also need to escape special regex characters `()`. — chris85, Jun 17 '17 at 17:34

This should do, assuming there is space after :

preg_match_all('/\((.+?)\): (.*)?/i', $subject, $array, PREG_PATTERN_ORDER);

This doesn't find `Type`s only. You also should explain what you did (the `i` modifier has no use because there are no alpha characters). – chris85 Jun 17 '17 at 17:35

i is for case insensitive to match the keyword, it finds type and content in binary array – Mason.Chase Jun 17 '17 at 18:25
`A`or `a` will be matched by `.` regardless of `i`. – chris85 Jun 17 '17 at 21:17
True , This was done by habit of keeping things case insensitive. you can remove it if you like. – Mason.Chase Jun 17 '17 at 22:01
