Regex matching multiline string failed.

$string ="<mytag>hhsfasfgia
fdhftgh</mytag>";

// the solution below was taken from a forum
// with or without this line doesn't make any difference
// some kind of windows and linux's difference in multiline
// $string = str_replace("\r\n","\n",$string);

$string = preg_match_all("/(<([\w]+)[^>]*>)(.*)(<\/\\2>)/m",$string,$match);
print '<pre>';
print_r($match);
print '</pre>';

PHP:

As u can see multiline mode is already ON but still it can't match the string. If i change the string to :

$string ="<mytag>hhsfasfgiafdhftgh</mytag>";

PHP:

It can match !

Any idea? Thank you.

 

$string = preg_match_all("/(<([\w]+)[^>]*>)(.*)(<\/\\2>)/s",$string,$match);

PHP:

 

Thanks, Jay! It works.

But i have a question, isn't m represents multi-line mode? and s represents single-line mode?

How come it works in single line mode?

Thank you anyway, +rep

 

You're welcome

m means that ^ and $ will match at line breaks (multiline) but s means that the . will match all characters including the newline
