How can you determine the size of an array in PHP?
To determine the size of an array in PHP, you can use the `count()` function. This function will return the number of elements in the array, allowing you to easily determine its size. Simply pass the array as an argument to the `count()` function to get the size.
$array = [1, 2, 3, 4, 5];
$arraySize = count($array);
echo "The size of the array is: " . $arraySize;
