php count the number of strings after exploded

Question

Here is my code

$key) {
$i >0;
    echo $i.\' \'.$key .         


        

Answer 1

$key) {

    echo $i.' '.$key .'
';

}

?>

Try using:

echo count($tags); // Output of 6

Arrays start with a key of 0, not one. So when using anything else apart from count, you will constantly get 1 less than your expected (unless you modify the array prior to counting)
