players
will either be empty or a comma separated 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']);
Best Answer
If you just need to check if there are ANY elements in the array
If you need to clean out empty values before checking (generally done to prevent
explode
ing weird strings):
