how to remove all margins from left side of multi line big string?

Question

i received a big string that has lots of margin in the left side(probably different sizes of margins) ! My current code doesn't remove it ? is there away to remove all those margins for entire bigstring content and all start lines start without any margin!

   $dataValue = $_POST['bigString'];

    $dataValue2 = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $dataValue);

the data has this type of margin:

    #EXTM3U

    #EXTINF:-1, title1
    http://somesite.com/2.m3u8

    #EXTINF:-1, title2
    http://somesite.com/2.m3u8

    #EXTINF:0, title 3

and i want to the the string to be like this:

#EXTM3U

#EXTINF:-1, title1
http://somesite.com/2.m3u8

#EXTINF:-1, title2
http://somesite.com/2.m3u8

#EXTINF:0, title 3

You can adapt this accepted answer to use ltrim:

$text = join(PHP_EOL, array_map("ltrim", explode(PHP_EOL, $text)));
