How can PHP developers avoid errors when defining new variables for additional videos in a playlist using SWFObject?

To avoid errors when defining new variables for additional videos in a playlist using SWFObject, PHP developers should ensure that they are properly formatting the variables and passing them correctly to the SWFObject script. They should also make sure to check for any syntax errors or typos in the variable definitions. 

<?php
$video1 = "video1.mp4";
$video2 = "video2.mp4";
$video3 = "video3.mp4";

echo "<script type='text/javascript'>
    var so = new SWFObject('player.swf','mpl','400','300','9');
    so.addVariable('file', '$video1');
    so.addVariable('playlist', '$video1,$video2,$video3');
    so.write('player');
</script>";
?>
