Glyde Posted April 19, 2007 Share Posted April 19, 2007 Well, I'm not going to try to figure out why array_rand gave you problems, but you could try: <?php function getRandom($array) { $keyList = array_keys($array); shuffle($keyList); $value = $array[$keyList[0]]; return $value; } $array = array('test' => 'asdf', 'dfgd', 't42' => 'sdf'); print getRandom($array); ?> Quote Link to comment https://forums.phpfreaks.com/topic/47817-solved-random-array-but-saving-key/#findComment-233640 Share on other sites More sharing options...
MadTechie Posted April 19, 2007 Share Posted April 19, 2007 could use array_keys to get the keys and then shuffle that array and use that ie <?php $Quests = array("1" => "Q1", "2" => "Q2", "3" => "Q3", "4" => "Q4", "5" => "Q5" ); $RandQ = array_keys($Quests); shuffle($RandQ); foreach($RandQ as $R) { echo $Quests[$R]; } ?> **UNTESTED Quote Link to comment https://forums.phpfreaks.com/topic/47817-solved-random-array-but-saving-key/#findComment-233644 Share on other sites More sharing options...
linuxdream Posted April 19, 2007 Share Posted April 19, 2007 <?php $data = array('somethign', 'nothing', 'again', 'and again', 'without', 'anything'); $rand = rand(0, count($data)-1); echo $data[$rand]; ?> Might work too.
