I want to compare two arrays in PHP

Question

Assume that I have two arrays as follow:

$array1 = array(1, 3, 5);
$array2 = array(\'x\'=> 1, \'y\'=> 2, \'z\'=> 5);

How to check that

Answer 1

In the simplest case you can just use array_diff. It ignores the keys in your second array, but also the order of the values. It would return an empty set if the arrays are equal:

 if (count(array_diff($array1, $array2)) == 0) {
    // equal

You could also compare the arrays directly, after stripping keys from the second:

 if ($array1 == array_values($array2)) {

That would additionally compare the order of contained values.
