如何在PHP中随机化？

Question

I'm trying to figure out how to randomize what text shows on a page in PHP.

I'm sure this is very easy but everything I search for related to this is talking about the shuffle() function - which isn't what I want to do.

I want half the time people go to my page for them to see "This is a test 1" and the other half of the time they should see "This is a test 2".

Any help would be appreciated.

Answer

I guess you mean pseudo-random when using PHP functions.

Also take a look at: http://www.php.net/manual/en/function.array-rand.php

<?php
    $texts = array("a", "b", "c");
    echo $texts[array_rand($texts, 1)]; // Output: a, b or c

I want half the time people go to my page for them to see "This is a test 1" and the other half of the time they should see "This is a test 2".

This means, you don't want random. Because when you use true-random it can happen that the output is This is a test 1 every time.
