PHP and regex to cut from begining to new line

I don't have any expirience in regex with php (just some copy/pasting for simple tasks) so I can't 'solve' simple situatio, and I hope that somone can help.

I have a lage files that look like:

xxxxxxxxxxxxxx
xxxxxxxxxxxxxxx
xxxxxxxxxxxxxx
text,text,text,
text,text,tec,etc

Now i need in php to write function where passed string with content like this will return me part that I marked here as 'xxx...' After every 'xxxx...' sequence at file begin, I have as you can see new line (\r\n) and I don't know how to use regex to to cut upper part into another string, so please help.

If the only part of the string separated by two new lines is the header series of 'xxxx' and the following 'text,text,text' lines, you could simply use explode. Passing a limit of 2 means it will only explode at the first instance of "\n\n", returning an array of at most 2 items:

list($header, $body) = explode("\n\n", $file_contents, 2);

I'd skip the regex.

$eol = strpos($s, "\r\n");
$header = substr($s, 0, $eol);
$rest = substr($s, $eol + 2);
