Regular expression to get text between 2 string

Question

Hi i need to get the content between 2 strings similar to tags like this:

[code]
some text and 
new line 
[/code]

I try with this regular expression but it works only without new line :

preg_match("/\[view\](.*)\[\/view\]/",$string, $results);

I need something that works also with newlines! and any characters i put between these 2 "tags" Any idea ?

Use the s modifier in your call to do a multiline search:

preg_match("/\[view\](.*)\[\/view\]/s",$string, $results);

In the end, you should not be using regex to do complex parsing. It isn't up to the job. Find a markup language that suits your purpose and use an existing library to parse it.

@Asap In fact it does not work with an m modifier; the correct answer is, as you say, the s modifier. Sorry for my previous incorrect answer...

Try running it against [view]foo[view]bar[/view]baz[/view], what will you get?

@ircmaxwell It's a good point, and I've added a note about using a real parser.
