There does not seem to be any mention of the PHP version of switches that can be used with regular expressions.
preg_match_all('/regular expr/sim',$text).
The s i m being the location for and available switches (I know about)
The i is to ignore letter cases (this is commonly known - I think)
The s tells the code NOT TO stop searching when it encounters \n (line break) - this is important with multi-line entries for example text from an editor that needs search.
The m tells the code it is a multi-line entry, but importantly allows the use of ^ and $ to work when showing start and end.
I am hoping this will save someone from the 4 hours of torture that I endured, trying to workout this issue.
