array_udiff_assoc
Synopsis
array array_udiff_assoc(arrayarray1
, arrayarray2
[, ... arrayarrayN
], stringfunction
)
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 function
is used to compare the
values of the elements for equality. The 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.
