数组减少变量中的返回布尔值

How I can return boolean type in variable? I have code:

$imageRes = array_reduce(['image', 'image1', 'image2'], function ($carry) {
    return in_array($carry, ['image1', 'image2']);
});

I need return in imageRes a boolean type: true/false, if one of the elements in ['image1', 'image2'] is in ['image', 'image1', 'image2']. How I can do it?

Use array_intersect() instead of array_reduce(), count the result of that and cast it to a boolean. If there are no intersections, the count() will be zero, thus a boolean false. If there are at least one value intersecting, the count() will be greater than one and any non-zero number cast to a boolean will be true.

$imageRes = (bool)count(array_intersect(['image1', 'image2'], ['image', 'image1', 'image2']));

Output:

bool(true)

• Live demo at https://3v4l.org/0INUP
• PHP.net on array_intersect()

If you just need to know if any of the elements are in both arrays use array_intersect(), count the result and cast to boolean(!!)

$ref_array = ['image1', 'image2'];
$array = ['image', 'image1', 'image2'];
$imageRes = !!count(array_intersect($array, $ref_array));
var_dump($imageRes);

A possible solution with array_reduce would be like this:

$imageRes = array_reduce(
    ['image', 'image1', 'image2',], 
    function($carry, $item) {
        return $carry || in_array($item, ['image1', 'image2']);
    },
    false //Initial value is false
);
