Generate A Random Colour With PHP

21st May 2008 - 1 minute read time

Here is a short bit of code to generate a random hexadecimal colour using PHP. Essentially you just create a random number between 0 (000000) and 10,000,000 (ffffff) and turn this into a hexadecimal number using the PHP function dechex.

  1. $colour = rand(0, 10000000);
  2. $colour = dechex($colour);

This can also be accomplished on a single line.

$colour = dechex(rand(0, 10000000));
