array_diff_key() 例子
<?php
$array1 = array(‘blue‘ => 1,
‘red‘ => 2, ‘green‘ => 3, ‘purple‘
=> 4);
$array2 = array(‘green‘ => 5,
‘blue‘ => 6, ‘yellow‘
=> 7, ‘cyan‘ => 8);
var_dump(array_diff_key($array1,
$array2));
?>
上例输出：array(2) { ["red"]=> int(2) ["purple"]=> int(4) }
array_diff_uassoc() 例子
<?php
function key_compare_func($a,
$b)
{
if
($a === $b) {
return 0;
}
return ($a > $b)? 1:-1;
}
$array1 = array("a" => "green", "b"
=> "brown", "c" =>
"blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result = array_diff_uassoc($array1, $array2, "key_compare_func");
print_r($result);
?>
上例输出：Array ( [b] => brown [c] => blue [0] => red )
