random image display

rajuru · September 5th, 2004, 09:36 AM

in a folder I have 5 images named:
add1.jpg, add2.jpg, add3.jpg, add4.jpg, add5.jpg

now I want to display random image when user click refresh or new visitor come to that page.
I have written this code
<?php
$add="add";
$add .= rand(1,5);
$add .=".jpg";
echo "<img border='0' src='$add' width='450' height='50'>";
?>
but i seen that this code always shows one image only

Please tell me how I can do it.

hey

i tried your code and it works totally fine... remember that you are using the rand() function, which generates numbers from 1 to 5, sometimes number occurrences can be same.

Dear thanks for reply,
But I tried using a larger inverval. Such as
rand(1,500)

I see the same number always
even I tried from network.
It shows same number all pcs

what can I do now

Looks like your code should work but try this anyway.

Code:

function writeRandomAd()
{
    $imgs = Array("add1.jpg","add2.jpg","add3.jpg","add4.jpg","add5.jpg");
    shuffle($imgs);
    echo "<img src='$imgs[0]' alt='click here!'/>";

HTH,
