In PHP, you can use the empty() function to check if an array is empty or not.

1
2
3
4
5

if (empty($array)) {
    // array is empty
} else {
    // array is not empty
}

You can also use the count() function to check the number of elements in an array:

1
2
3
4
5

if (count($array) === 0) {
    // array is empty
} else {
    // array is not empty
}

Alternatively you can also use the !$array to check if array is empty.

if (!$array) {
    // array is empty
} else {
    // array is not empty
}

Note: empty() will return TRUE if the array has no elements, or if all of its elements are FALSE, and count() function returns the number of elements in an array.
