Random text load script

[Zola]

Hi,

 

I am wanting to create a random fact script for a small website project.

 

The idea is when the user loads a page a random fact will appear at the top ( I guess from an array of strings I will make?)

 

Can anyone recommend the most efficient and easiest way to go about this please?

I found this code, can someone explain it a little to me please?

 

<?php
$random_text = array("Random Text 1",
                    "Random Text 2",
                    "Random Text 3",
                    "Random Text 4",
                    "Random Text 5");

$sizeof = count($random_text);
$random = (rand()%$sizeof);
print("$random_text[$random]");


?>

 

Why do we need the $sizeof and count?

 

[dzelenika]

count() — Count all elements in an array

rand — Generate a random integer

$random = (rand()%$sizeof  limits generated number 0 to $sizeof

Sorry for the noob questions, but I am learning all about this stuff.

 

Thanks very much
