Yes, but not because if this reason.
If you for example reference an array index in your code, you do this for a reason. If it doesn't exist, you will get a notice, but your script continues with a value for that array element that PHP 'invented', and that can cause your application to do something completely different then what you intended.
Every notice, warning or error issued by PHP is a BUG in your code, and should be rectified, not ignored.
If you don't, you produce sloppy and unpredictable code, and you wouldn't be a programmer that I would like to employ.
