Synopsis
array array_udiff_uassoc(arrayarray1, arrayarray2[, ... arrayarrayN], stringfunction1, stringfunction2)
Returns an array containing all the values in
array1 that are not present in any of the
other arrays. Both keys and values are used to check for equality;
that is, “a” ⇒ 1 and “b” ⇒ 1 are not considered equal. The function
function1 is used to compare the values
of the elements for equality. The function
function2 is used to compare the values
of the keys for equality. Each function is called with two
parameters—the values to compare. It should return an integer less
than 0 if the first argument is less than the second, 0 if the first
and second arguments are equal, and an integer greater than 0 if the
first argument is greater than the second. The keys of the values
are preserved.
