[PHP-DEV] array_diff not working with last element different
When using array diff, if the last element and only the last element is
different it won't be returned as a difference.
?
$ar = array(b = 1, blah = 1);
$a1 = array(b = 2, blah = 2);
var_dump(array_diff($ar, $a1));
?
array(2) {
[b]=
int(1)
[blah]=
int(1)
}
?
$ar = array(b = 1, blah = 1);
$a1 = array(b = 1, blah = 2);
var_dump(array_diff($ar, $a1));
?
array(0) {
}
I can't look at this right now maybe I can later or tomarrow.

I guess this may not be clear from documentation. array_diff() works
with values. So it will return all values from first array that are
not in the others. Since the value 1 is present in $a1, all elements
of value 1 are removed from $ar in the returned array.

Only remove (key, value) pair from 1st array if it exists in any of the others? Same goes for array_intersect... I'm not sure if there is that much of a need, but if there is one could either have new associative ones, or flags to the existing ones. But first we should see if there is a real need, then we need to see if someone will implent it.

Re: [PHP-DEV] array_diff not working with last element different
