Check if all values in array are the same

Question

I need to check if all values in an array equal the same thing.

For example:

$allValues = array(
    \'true\',
    \'true\',
    \'true\',
);
         


        

Answer 1

Another option:

function same($arr) {
    return $arr === array_filter($arr, function ($element) use ($arr) {
        return ($element === $arr[0]);
    });
}

Usage:

same(array(true, true, true)); // => true
