[SOLVED] rand() Issue

[Altec]

I'm using this code to pull random slogans to display on my site:

<?php

$slogans = array(
     'rawr1',
     'rawr2',
     'rawr3'
);

echo $slogans[floor(rand(0,count($slogans)))];

?>

However, sometimes it doesn't return anything (nothing is echo'd out). Why is that, and is there a better way to do this?

[Andy-H]

<?php
$slogans = array(
     'rawr1',
     'rawr2',
     'rawr3'
);
$slogans = shuffle($slogans);

echo $slogans[0]; 

?>

Ran into a slight issue. I'm not getting any output.

 

EDIT: It returns a boolean only; took out the variable definition.

EDIT2: Use this instead:

echo $slogans[array_rand($slogans)];

[Andy-H]

<?php
$slogans = array( 'rawr1', 'rawr2', 'rarw3' );

shuffle($slogans);

echo $slogans[0];

?>

 

Edit:

Thats why, it takes a reference and returns boolean, lol sorry, that will work =P

You can use what you were using by have to add an offset of -1.

 

$slogans[(rand(0,count($slogans)-1)];

 

This is because arrays start at [0], and count returns the number of elements in the array. In your case 3. Sometimes it could come out with $slogans[3], when your array only includes $slogans[0]-[2]
