Random Rotation Script

Hello,

I have used the following php script to get random text in my website...

<?php
$number=mt_rand(1, 6);

if ($number=="1") {

include "navrandom1.php";

}

if ($number=="2") {

include "navrandom2.php";

}

if ($number=="3") {

include "navrandom3.php";

}

if ($number=="4") {

include "navrandom4.php";

}

if ($number=="5") {

include "navrandom5.php";

}

if ($number=="6") {

include "navrandom6.php";

}
?>

HTML:

... each .php page is simply a paragraph and it works just fine, however, I was hoping to add about 20 different items as oppose to the current 6. Is there a shortcut in doing this or do I have to put...

[HTML]<?php
if ($number=="?") {

include "navrandom?.php";

}

HTML:

for each single item. Also, is there a way to put all the paragraphs in one page and have the script randomly choose one paragraph to display?

 

include("navrandom{$number}.php");

PHP:

 

You could use arrays.

$paragraphs = array(
    '<p>Paragraph 1</p>',
    '<p>Paragraph 2</p>',
    '<p>Paragraph 3</p>',
    '<p>Paragraph 4</p>',
);

$random = $paragraphs[array_rand($paragraphs)];

echo $random;

PHP:

 

edit:
better options have been suggested

 

Works beautifully. Thanks a bunch!
