array_diff_ukey
ARRAY_DIFF_UKEY(3) 1 ARRAY_DIFF_UKEY(3)array_diff_ukey - Computes the difference of arrays using a callback function on the keys for comparisonSYNOPSIS
array array_diff_ukey (array $array1, array $array2, [array $...], callable $key_compare_func)
DESCRIPTION
Compares the keys from $array1 against the keys from $array2 and returns the difference. This function is like array_diff(3) except the
comparison is done on the keys instead of the values.
Unlike array_diff_key(3) a user supplied callback function is used for the indices comparison, not internal function.
PARAMETERS
o $array1
- The array to compare from
o $array2
- An array to compare against
o $...
- More arrays to compare against
o $key_compare_func
- The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to
be respectively less than, equal to, or greater than the second.
int callback (mixed $a, mixed $b)
RETURN VALUES
Returns an array containing all the entries from $array1 that are not present in any of the other arrays.
EXAMPLES
Example #1
array_diff_ukey(3) example
<?php
function key_compare_func($key1, $key2)
{
if ($key1 == $key2)
return 0;
else if ($key1 > $key2)
return 1;
else
return -1;
}
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_diff_ukey($array1, $array2, 'key_compare_func'));
?>
The above example will output:
array(2) {
["red"]=>
int(2)
["purple"]=>
int(4)
}
NOTES
Note
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using
array_diff_ukey($array1[0], $array2[0], 'callback_func');.
