How to enable color for PHP CLI?

First we use an escape character so we can actually define a output color. This is done with \033 (\e). Then we open the color statement with [31m. Red in this case.

The "some colored text" will be the text outputted in a different color. And after that we have to close the color statement with \033[0m.

php -r 'echo "\033[31m some colored text \033[0m some white text \n";'

ref 1

ref 2

For lazier

function colorLog($str, $type = 'i'){
    switch ($type) {
        case 'e': //error
            echo "\033[31m$str \033[0m\n";
        break;
        case 's': //success
            echo "\033[32m$str \033[0m\n";
        break;
        case 'w': //warning
            echo "\033[33m$str \033[0m\n";
        break;  
        case 'i': //info
            echo "\033[36m$str \033[0m\n";
        break;      
        default:
        # code...
        break;
    }
}
