How can the count function in PHP be used to determine the number of elements in an array generated by explode?

To determine the number of elements in an array generated by explode in PHP, you can use the count function. After using explode to split a string into an array, you can then pass that array to the count function to get the number of elements in the array. This is useful when you need to know the number of substrings created by explode.

$string = "apple,banana,orange";
$array = explode(",", $string);
$count = count($array);

echo "Number of elements in the array: " . $count;
