NAME
	member_array - find the position of an element in an array

SYNOPSIS
	int member_array(mixed element, mixed *array)

DESCRIPTION
	Gives the index in 'array' which is occupied with the value 'element'.
	If 'element' is not found or an integer is given instead of an array
	as second argument, -1 is returned.

	Searching works like the equality operator, ie integers and strings
	are compared for equality and arrays and mappings for identity.

	This means that integers and strings must have the same value to match,
	while arrays and mappings must be the exactly same.
