function cf_is_empty_or_non_array in Common Functionality 7.2

Checks if a variable is an empty array is empty or not an array at all.

Justification: Checking that an array is empty may also require a check to see if a variable is an array. This provides a way to do that two step process in 1 step. Do not use this for any other purpose.

Parameters

string $argument_name: The variable name of the argument in question.

$variable: The argument that is to be validated.

int $severity: (optional) This is passed directly to watchdog and represents the severity of the report.

Return value

bool When the check passed returns TRUE, FALSE otherwise.
