Probably it's "Undefined Index".You must have seen it in some of the PHP notices or warnings.It comes, when you are working with arrays and the Index or Key your code is using doesn't actually exist.For Example,if you define an array:$a = array( 'a'=>'pak' , 'b' => 'asif' );having two Indexes (a & b),But later on, you code like:$a['c'];Now, c index doesn't actually existed in $a array, so a PHP warning / notice will appear on run time saying:Undefined Index 'c' ....Hope this help you!
