EASY: can someone fix this.

<?php
$q = rand(0 , 3);

if ($q==0){
$say = "Welcome";
}

if ($q==1){
$say = "HI";
}

if ($q==2){
$say = "🙂";
}

if ($q==3){
$say = "Yes.. php.net";
}

echo $say;

?>

Is there anyway to make it like this

$say = array [welcome, hi, 🙂, yes php.net]

echo rand ($say)

Consider [man]array_rand/man.

<?php
srand((float) microtime() * 10000000);
$input = array("Welcome", "Hi", "", "Yes.. php.net");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]];
?>

I think that'd work..

[drcolby]

hmm.. that didnt work

[Sesquipedalian]

Gah, that's not the way I'd normally do it, I was just trying to use the array_rand.. This is how I'd do it:

<?php
srand(time());
$r = (rand()%4);
$input = array("Welcome", "Hi", "", "Yes.. php.net");
echo $input[$r];
?>

If that doesn't work, just call me stupid and slap me.

hm i did it like this

<?php


$q = rand(0 , 2);

$say = array("welcome","hi","php.new is soo cool");

echo $say[$q];

?>

whats the difference or the benefit. Thanks!

Well, as of PHP 4.2.0, [man]srand/man isn't needed.

If you want to use a faster, better randomizer, use [man]mt_rand/man instead. Alternatively, [man]array_rand/man could be used:

$say = array("welcome","hi","php.new is soo cool");

echo $say[array_rand($say, 1)];
