The PHP port of the YUI CSS Compressor is a powerful tool designed to help web developers compress their CSS files effortlessly. In this guide, we will walk you through the installation requirements, usage instructions, troubleshooting tips, and how to ensure your CSS is optimally compressed.

1. Installation Requirements

To get started with the YUI CSS Compressor, follow these installation steps:

• Ensure you have PHP version 5.3.2 or newer installed on your system.
• Install Composer, which you can download from getcomposer.org.

2. How to Use the YUI CSS Compressor

The library offers three different ways to use it: PHP, CLI, and GUI. Below, we will explore the PHP method in detail.

2.1 Using PHP

To compress your CSS using PHP:

• First, load the Composer autoloader:

require .vendor/autoload.php;

• Use the CSSmin class:

use tubalmartin\CssMin\Minifier as CSSmin;

• Next, extract the CSS code you want to compress:

$input_css = file_get_contents('test.css');

• Create a new CSSmin object:

$compressor = new CSSmin;

• Configure your compressor settings:
• To keep sourcemap comments, use:

$compressor->keepSourceMapComment();

• To remove important comments, utilize:

$compressor->removeImportantComments();

• Set a line break position to split long lines:

$compressor->setLineBreakPosition(1000);

• Finally, compress your CSS:

$output_css = $compressor->run($input_css);

• Output the compressed CSS:

echo $output_css;

2.2 Using CLI

The binary file named ‘cssmin’ is available for command-line usage after installation. You can compress a CSS file directly from your command line:

• Output to the command line:

./vendor/bin/cssmin -i my-css-file.css

• Output to another file:

./vendor/bin/cssmin -i my-css-file.css -o my-css-file.min.css

2.3 Using GUI

The GUI offers a user-friendly interface for compression. Here’s how to set it up:

• Ensure your server runs PHP 5.3.2 or newer.
• Download the repository and upload it to your server.
• Run composer to install dependencies:

php composer.phar install

• Navigate to the GUI folder in your web browser.

3. Troubleshooting

If you encounter issues while using the YUI CSS Compressor, consider these troubleshooting steps:

• Verify if your PHP version meets the requirements.
