PHP CLI colors

Simple color constants to output background / foreground colors in cli (bash, cmd, powershell…)

Why?

There are several options to colorize CLI outputs from PHP but I find them innecesary complex (from my point of view), I think it’s much easier use some well defined constants instead classes and objects.

How to use

echo cli_red, "My string", cli_eol;
// Outputs "My string" in red color and a final breakline (\n)
echo cli_yellow, cli_blue_bg, "My string", cli_eol;
// Outputs "My string" in yellow over blue background and a final breakline (\n)

It’s important yo notice that color settings will continue to affect CLI outputs in all the sebseuquential echoes. To reset the CLI colors to it’s default values use cli_reset;

echo cli_red, "Red text", cli_ellow, "Yellow text", cli_eol;
echo cli_reset, "This will be in default CLI color.", cli_eol;
