PHP Question

How to tell if a PHP array is empty?

will either be empty or a comma seperated list (or a single value). What is the easiest way to check if it's empty? I'm assuming I can do so as soon as I fetch the
array into
? In this case it would probably be more efficient to skip exploding the
if it's empty, but for the sake of argument, how would I check if an array is empty as well?

$gamerow = mysql_fetch_array($gameresult);
$playerlist = explode(",", $gamerow['players']);



If you just need to check if there are ANY elements in the array

if (empty($playerlist)) {
     // list is empty.

If you need to clean out empty values before checking (generally done to prevent explodeing weird strings):

foreach ($playerlist as $key => $value) {
    if (empty($value)) {
if (empty($playerlist)) {
   //empty array
