php get file content with explode -

i file content of usual txt file array explode. unfortunately if use usual file open opens file, seperates lines. not useful format this:

date|name|specialtext|description|

but can happen description has several lines, s why usual method not working.

i tried here:

$lines = file($filename1);     foreach ($lines $line) {         if (preg_match('/^\s*|+\r*$/', $line)) { echo "finally"; }

| should sperator. not work.
