Php colored console output

How to enable color for PHP CLI?

Enabling color for PHP CLI can be useful for improving the readability of the output on the command line. Here is a step-by-step guide on how to enable color for PHP CLI:

1. First, make sure that the PHP version you are using supports color output. You can check this by running the following command:

`php -r “echo ‘Color support: ‘.(int)function_exists(‘sapi_windows_vt100_support’);”`

If the output is `Color support: 1`, then your PHP version supports color output. If the output is `Color support: 0`, then you need to upgrade your PHP version.

1. Next, you need to install the Symfony Console component. This component provides an easy-to-use API for building command-line applications in PHP, including color output. You can install it using Composer:

`composer require symfony/console`

1. Once you have installed the Symfony Console component, you can start using it to enable color output in your PHP CLI scripts. Here is an example:

“`php
require DIR.’/vendor/autoload.php’;

use Symfony\Component\Console\Output\ConsoleOutput;
use Symfony\Component\Console\Formatter\OutputFormatterStyle;

// create a new ConsoleOutput object
$output = new ConsoleOutput();

// create a new OutputFormatterStyle object and customize the colors
$style = new OutputFormatterStyle(‘red’, ‘yellow’, array(‘bold’, ‘blink’));

// register the new style with the ConsoleOutput object
$output->getFormatter()->setStyle(‘fire’, $style);

// output some text in the new style
$output->writeln(‘Fire!’);
“`

In this example, we create a new `ConsoleOutput` object, which represents the output stream of the PHP CLI script. We then create a new `OutputFormatterStyle` object, which defines the colors for our custom style. We register the new style with the `ConsoleOutput` object, and then use it to output some text in the new style using the `writeln()` method.

1. You can also use the built-in colors provided by the Symfony Console component. Here is an example:

“`php
require DIR.’/vendor/autoload.php’;

use Symfony\Component\Console\Output\ConsoleOutput;
use Symfony\Component\Console\Formatter\OutputFormatterStyle;

// create a new ConsoleOutput object
$output = new ConsoleOutput();

// output some text in the default red color
$output->writeln(‘Hello, world!’);

// output some text in the default green color
$output->writeln(‘Goodbye, world!’);
“`

In this example, we use the built-in colors provided by the `ConsoleOutput` object. We can use the `fg` option to set the foreground color and the `bg` option to set the background color.

That’s it! With these steps, you can enable color output for your PHP CLI scripts and make them more readable and visually appealing.

How to Use Colors in Command-line PHP Output

Nothing spruces up command-line output the way colors do. Just like when you’re customizing your [Bash] prompt, you can use color codes in strings to colorize your output. Keep in mind, these colors will only work on the command-line and not in a browser. First let’s take a look at the syntax:

echo "\e[0;31;42mMerry Christmas!\e[0m\n"; 

The above command will echo out “Merry Christmas!” in a red font with a green background. The first part of the string, \e is the escape character and could alternatively be represented by \033 in octal or using the function call chr(27) if you want to close and reopen the string a bunch of times.

Next up is [0;31;42m , this is what sets the foreground color ( 0;31 ) and the background ( 42 ). This is all followed up by the text we’re colorizing. After that is another color declaration that will reset the color to the terminal’s default colors (usually grey text on a black background).

So now that we know how to colorize text, let’s take a look at all of the colors that are available. All in there are 16 different foregrounds and 8 backgrounds. Of the foregrounds, they are split between a normal colors and lighter alternate versions that actually end up being displayed differently depending on the terminal being used. Sometimes they are heavier text, sometimes alternative colors. The colors and codes are as follows:

Foreground Colors

Color	Code
Black	0;30
Dark Grey	1;30
Red	0;31
Light Red	1;31
Green	0;32
Light Green	1;32
Brown	0;33
Yellow	1;33
Blue	0;34
Light Blue	1;34
Magenta	0;35
Light Magenta	1;35
Cyan	0;36
Light Cyan	1;36
Light Grey	0;37
White	1;37

Background Colors

It’s worth noting that you actually don’t need to set both the foreground and the background color, if you wanted to you could simply set one or the other using the aforementioned codes. When defining both, you must specify the foreground color first and just separate the codes with a semi-colon.

composer require alecrabbit/php-console-colour

$themes = new Themes(); echo $themes->red('This text is red.') . PHP_EOL; echo $themes->underlinedBold('This text is underlined and bold.') . PHP_EOL;

Basically methods of this class just applying corresponding escape sequences to $text

// "\033[2;3mThis text is dark and italic.\033[0m" $colorized = $themes->darkItalic('This text is dark and italic.')

Note: not all methods could be listed.

/** * @method comment(string $text) * @method error(string $text) * @method info(string $text) * * @method yellow(string $text) * @method red(string $text) * @method green(string $text) * @method cyan(string $text) * @method magenta(string $text) * * @method italic(string $text) * @method bold(string $text) * @method dark(string $text) * @method darkItalic(string $text) * @method white(string $text) * @method whiteBold(string $text) * @method underlined(string $text) * @method underlinedBold(string $text) * @method underlinedItalic(string $text) */

Note: new methods will be added. Pull requests are welcomed.

Note: actual colors depend on your terminal color scheme
