A Simple PHP class for wrapping your console/terminal output text in color. Keep in mind that building a class for such projects will require customization as each terminal emulator will process colors a bit differently. For the most part, the colors in this class work with any popular terminal emulator.
<?php
class CLI
{
// this function requires 1 variable, content. The color arguement is optional.
function cout_color($content, $color=null)
{
// if a color is set use the color set.
if(!empty($color))
{
// if our color string is not a numeric value
if(!is_numeric($color))
{
//lowercase our string value.
$c = strtolower($color);
}
else
{
// chec if our color value is not empty.
if(!empty($color))
{
$c = $color;
}
else
{
// no color was set so lets pick a random one...
$c = rand(1,14);
}
}
}
else// no color @paramter was passed, so lets pick a random one...
{
$c = rand(1,14);
}
$cheader = '';
$cfooter = "\033[0m";
// let check which color code was used so we can then wrap our content.
switch($c)
{
case 1:
case 'red':
// color code header.
$cheader .= "\033[31m";
break;
