Title
Body
I have an array with numerous dimensions, and I want to test for the existence of a cell. The below cascaded approach, will be for sure a safe way to do it: if (array_key_exists($arr, 'dim1Key')) if (array_key_exists($arr['dim1Key'], 'dim2Key')) if (array_key_exists($arr['dim1Key']['dim2Key'], 'dim3Key')) echo "cell exists"; But is there a simpler way? I'll go into more details about this: Can I perform this check in one single statement? Do I have to use array_key_exist or can I use something like isset? When do I use each and why?
