How can the issue of an empty array returning a count of 1 be resolved using is_array instead of count?

When using the count function on an empty array in PHP, it will return 1 instead of 0. This is because an empty array is considered as having one element, which is the empty array itself. To resolve this issue, you can use the is_array function to check if the variable is an array before counting its elements. This way, you can ensure that an empty array will return a count of 0. 

$array = []; // Empty array

if (is_array($array)) {
    $count = count($array);
} else {
    $count = 0;
}

echo $count; // Output: 0
