How to check whether an array is empty using PHP?

How to check whether an array is empty using PHP?

players will either be unfilled or a comma-isolated list (or a single value). What is the least demanding approach to check if it's empty? I'm expecting I can do as such when I bring the $gameresult array into $gamerow? For this situation it would most likely be more productive to skip exploding the $playerlist if it's blank, however for contention, how might I check if an array is empty too?

$gamerow = mysql_fetch_array($gameresult);

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

array php

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

}

Use this code to check whether an array is empty or not.



<?php

$playerList = array();

if (!$playerList) {

    echo "No players";

} else {

    echo "Explode stuff...";

}

// Output is: No players
