The example in this article describes how to simply generate random colors in php. Share it with everyone for your reference, the details are as follows:
<?php //第一种方法: $rand = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'); $color = '#'.$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)]; echo $color."<br/>"; //第二种方法: printf( "#%06X\n", mt_rand( 0, 0xFFFFFF )); ?>
The running results are as follows:
#4338cd #7EF5B8
