Re: array intersect

[Chis Florinel]

array_intersect() function will return the common values found in those 2 arrays, key is ignored.

so

$array1 = array('key_1' => "sameValue");
$array2 = array('key_2' => "sameValue");


$commonResults = array_intersect($array1, $array2);
var_dump($commonResults);

will output:
array(1) {
["key_1"]=>
string(9) "sameValue"
}


array_intersect_assoc() will test if the keys AND the values are the same.

$commonResults = aarray_intersect_assoc($array1, $array2);
var_dump($commonResults);

will output an empty array:
array(0) {
}

Hope it helps
