In the context of PHP development, how can one ensure that a value is countable before using the "count()" function?

To ensure that a value is countable before using the "count()" function in PHP, you can use the "is_countable()" function to check if the value is an array or an object implementing the Countable interface. This helps prevent errors when trying to count non-countable values like integers or booleans.

$value = [1, 2, 3]; // Example value to check

if (is_countable($value)) {
    $count = count($value);
    echo "The count of the value is: " . $count;
} else {
    echo "The value is not countable.";
}
