How to check if an array is empty in PHP?

To check if an array is empty in PHP, you can use the empty() function or the count() function. Here are the examples:

Using empty() function:

$array = array(); // or $array = []

if (empty($array)) {
    echo "Array is empty";
} else {
    echo "Array is not empty";
}

Using count() function:

$array = array(); // or $array = []

if (count($array) == 0) {
    echo "Array is empty";
} else {
    echo "Array is not empty";
}

Both empty() and count() functions will return true if the array is empty and false otherwise.
