How to check whether an array is empty using PHP

Question

I have an array named players, what is the best way to check if it is empty or not?

Answer 1

To do this you can use the array itself, due to PHP's loose typing, or if you prefer a stricter approach - use count():

if (!$playerlist) {
     // list is empty.
}
if (count($playerlist) === 0) {
     // list is empty.
}

 To prevent explodeing weird strings you have to clean out empty values before checking :

foreach ($playerlist as $key => $value) {
    if (!strlen($value)) {
       unset($playerlist[$key]);
    }
}
if (!$playerlist) {
   //empty array
}

I hope this helps you.
