How to determine if an array has any elements or not?

Question

How do I find if an array has one or more elements?

I need to execute a block of code where the size of the array is greater than zero.

if ($result &

If you want to only check if the array is not empty, you should use empty() - it is much faster than count(), and it is also more readable:

if (!empty($result)) {
    // ...
} else {
    // ...
}
