Name
array_diff_uassoc
Synopsis
array array_diff_uassoc(arrayarray1
, arrayarray2
[, ... arrayarrayN
], stringfunction
)
Returns an array containing all the values in
array1
that are not present in any of the
other arrays. Unlike array_diff(
)
, both the keys and values must match to be considered
identical. 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.
