Question

I currently have a piece of code that is selecting random values from an array but I would like to prevent it from selecting duplicate values. How can I achieve this? This is my code so far:

$facilities = array("Blu-ray DVD Player","Chalk board","Computer", "Projector",
"Dual data projector", "DVD/Video");

for($j = 0; $j < rand(1, 3); $j++)
   {
    $fac =  print $facilities[array_rand($facilities, 1)] . '<br>'; 
   } 

Answer 1

I think you should look at array_rand

$facilities = array("Blu-ray DVD Player","Chalk board","Computer","Data projector","Dual data projector","DVD/Video");
$rand = array_rand($facilities, 2);
                                ^----- Number of values you want 

foreach ( $rand as $key ) {
    print($facilities[$key] . "<br />");
}
