Question

I have the following code

$pattern = '#\bset_message\("(.*?)"\)#';
$found = preg_match($pattern, $string, $matches);

But if my $string is

set_message("Hello there
I like
to 
eat
CHEES!");

it doesn’t return anything for matches, but it does if I use

set_message("Hello there!");

how can I add new lines and stuff like that (\r\n, \n, etc)?

Answer 1

Just use m modifier.

$pattern = '#\bset_message\("(.*?)"\)#m';

When you want that . could mean \n also, you need to use both m' ands` modifiers:

$pattern = '#\bset_message\("(.*?)"\)#ms';
