PHP Question

How to check whether an array is empty using PHP?

players
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
$gameresult
array into
$gamerow
? In this case it would probably be more efficient to skip exploding the
$playerlist
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']);


Thanks!

Answer

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)) {
       unset($playerlist[$key]);
    }
}
if (empty($playerlist)) {
   //empty array
}
