如何匹配所有“类型”并正确地转义正则表达式？

我目前努力下面的“类型”的内容相匹配：

(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? 

我想：

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

但我得到一个未知的修饰词“\”的错误消息。

如何正确匹配所有类型？感谢任何提示！

这应该做的，假设有空间后：

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