Solution 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";'

ref 1

ref 2

Solution 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;
    }
}

Solution 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 :)

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?

yes, it worked after I replaced \e with 033. Thank you.

Or do not rely on echo's sequences, and instead directly generate the ANSI sequences within the string using ANSI-C quoting: $'\e[31mblah blah\e[0m. This way you don't need to remember \033 or whatever.

single quotes will not work by the way :) use double quotes

+1 super helpful. FYI if anyone else needs help looking up color codes.

any way to get this to work when a PHP script is run via tty? Works from CLI normally but not in any git bash instances running in embedded terminals. (other commands show colours tho in the same setup)

This is a much better answer than the accepted answer

this would make a good helper function, also the time would be nice, $date = date('h:i:s', time());
