ansi::[colors] is a simple library for PHP CLI applications. Made for simplicity, it avoids complicated methods for ANSI code output.

By complicated methods I mean something like:


    $color = new \MyNamespace\ANSISuperClass::color_factory(\MyNamespace::ANSI_RED_COLOR);
    echo $color->generate_ansi_codes("E");


You get the point. I want to avoid a "FactorySingletonGenerator" to just print a red "E".


Just use Composer. Add this to your composer.json:

    "require" : {
        "twoixter/ansicolors" : "~1.0"

Or you just can download the lib/ansi.php file to your own source directory. Require it and you're ready to go.


ansi:[colors] uses a global Class. You don't need to instantiate it, just use it's static methods. If the name ansi in lower case collides with some other global class of your own, please rename your class. :-)

Example usage without arguments:

<?php echo ansi::red()."this is red".ansi::reset(); ?>

Note that you need to ansi::reset() if you don't use arguments or your text will be red forever, even when you exit the PHP script.

Alternatively, you can put some strings inside the method:

<?php echo ansi::red("this is red");  # No need to reset ?>

The string this is red will be printed in red and automatically reset to the previous console color.

Available colors

Available colors are the usual suspects: black, red, green, yellow, blue, magenta, cyan and white.

Use then as static methods to the ansi class:


...and so on. They return a string containing the ANSI escape sequences, you must output it yourself, nothing is automatically echoed to the console.

Uppercase and lowercase methods

The above eight color names are lowercase. It is on purpose. Lower case name colors are dull, the brighter ones are UPPERCASE or CamelCased. Example:

ansi::White(...)    # Bright white. Alternate: ansi::WHITE()
ansi::Red(...)      # Bright red. Alternate: ansi::RED()

Background colors

You can not change the background color on its own, you must add also a foreground color using the following form:

<? echo ansi::Red_on_white("Yep!"); ?>

The string Yep! will use a bright red foreground color over a white background. Background colors are all dull, Red_on_White has no effect, even when using all uppercase.

You can use all combinations of colors for foreground and background. Examples:

ansi::Red_on_white(), ansi::White_on_blue(), ansi::Black_on_green()...

Named colors

ansi::[colors] supports color aliasing as named colors. Use ansi::define("name", "color"); to create a new named color.



    # Define some new color names
    ansi::define("error", "Red_on_white");
    ansi::define("success", "Green");

    # Definitions can be recursive
    ansi::define("default", "success");

    # Use the new named colors
    echo ansi::success("The file has been copied successfully!");
    echo ansi::error("Watch out! Something went wrong...");


Support for pipes

ansi:[colors] is smart enough to disable itself when piped. So you can do things like:

$ php myscript.php | less
$ php myscript.php > output_file.txt

And you can be sure no ANSI codes will mangle your output. Perfect for logging to file for example, or using less to paginate.
