How to enable color for PHP CLI?

Question

How do I enable the colors for output of CLI? The below one is, running on Ubuntu.

If you see the screenshot, obviously the colors is enabled for terminal. And, if I call echo, it doesn't colorize the result, but if I use echo -e, it colorizes.
I checked manual page of echo, and -e means enable interpretation of backslash escapes
How can I enable this option for PHP CLI?

Answer 1

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";'

Answer 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;
    }
}

Answer 3

After doing some experiments, I made these codes:

function formatPrint(array $format=[],string $text = '') {
  $codes=[
    'bold'=>1,
    'italic'=>3, 'underline'=>4, 'strikethrough'=>9,
    'black'=>30, 'red'=>31, 'green'=>32, 'yellow'=>33,'blue'=>34, 'magenta'=>35, 'cyan'=>36, 'white'=>37,
    'blackbg'=>40, 'redbg'=>41, 'greenbg'=>42, 'yellowbg'=>44,'bluebg'=>44, 'magentabg'=>45, 'cyanbg'=>46, 'lightgreybg'=>47
  ];
  $formatMap = array_map(function ($v) use ($codes) { return $codes[$v]; }, $format);
  echo "\e[".implode(';',$formatMap).'m'.$text."\e[0m";
}
function formatPrintLn(array $format=[], string $text='') {
  formatPrint($format, $text); echo "\r\n";
}

//Examples:
formatPrint(['blue', 'bold', 'italic','strikethrough'], "Wohoo");
formatPrintLn(['yellow', 'italic'], " I'm invicible");
formatPrintLn(['yellow', 'bold'], "I'm invicible");

Just copy and paste the code above and... Enjoy :)
