Can anyone help me? Thanks a lot!

Answer 1

$videoArray = file('youtube_vids.txt');
$randomIndexes = array_rand($videoArray, 4);
foreach ($randomIndexes as $index) {
    echo '<iframe width="420" height="315" src="'.preg_replace( "/\r|\n/", "", str_replace('|','',$videoArray[$index])).'"></iframe>';
}

will output

<iframe width="420" height="315" src="https://www.youtube.com/embed?v=dQw4w9WgXcQ"></iframe>
