Post Randomising Text Colour 
 
Mmm? I can't post in "PHP Scripts" so I'll dump it here.

Here's a cute little thing that I found in my travels that randomises the colour of texts etc - - - -

Da Script:

Code: [Download] [Hide] [Select]
<?php
function get_random_color()
{
    for ($i = 0; $i<6; $i++)
    {
    $c .=  dechex(rand(0,15));
    }
    return "#$c";
}
?>


Da Usage Sample:

Code: [Download] [Hide] [Select]
<?php
echo '<span style="color:'.get_random_color().'; font-weight: bold;">'.$r['username'].'</span><br />';
?>


And one gets something like this:

Joshua

Thanks for sharing Mort, there are similar (not identical!) scripts in bbcode.php that you can use here.

Code: [Download] [Hide] [Select]
    /**

            5 => 'blue',
            6 => 'indigo',
            7 => 'violet'
        );
    }

    /**

    */
    function rainbow($text)
    {
        // Returns text highlighted in rainbow colours
        $colors = $this->load_rainbow_colors();

Yep, I knew that was there Luca , but IMHO they're both toys for those who don't know any better.  

Both have foreground-background colour compatibility problems with words and letters disappearing, and that's what I mean by toys!

Imagine if one was to script them to use the forum css tags?


No maybe not!

Post Re: Randomising Text Colour 
 
I am currently successfully using the following code to randomly change the color of specified text ("quotations" - see below) each time the page is reloaded. The only problem is that the colors are too random. Instead of the code I now have, I'm looking for code that would allow me to define a distinct list of colors through which the text would randomly rotate each time the page loads. In other words, I want to choose each of the randomly loaded colors of my text. Hope that makes sense... Perhaps some kind of an array?

Hi, sorry for the delay.

Can you tell me which colors you'd like?
