The sabberworm/php-css-parser is a PHP library that provides a comprehensive parsing solution for CSS files. It allows developers to read CSS files into a data structure that can be manipulated and output as optimized CSS. This makes it possible to work with CSS files programmatically, offering a high degree of control and flexibility.
To make use of the sabberworm/php-css-parser, you need to first install it via Composer using the command composer require sabberworm/php-css-parser. Once installed, you can create a new instance of the Parser and read a file using example code like the one below:
$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
$cssDocument = $parser->parse();
The resulting CSS document structure can then be manipulated prior to being output. There are settings to control character sets, enable strict parsing, and disable multibyte functions. Here's a code snippet showing how to manipulate the CSS.
$myId = "#my_id";
$parser = new \Sabberworm\CSS\Parser($css);
$cssDocument = $parser->parse();
foreach ($cssDocument->getAllDeclarationBlocks() as $block) {
foreach ($block->getSelectors() as $selector) {
$selector->setSelector($myId.' '.$selector->getSelector());
}
}
Finally, you can output the CSS by using the render() method:
print $cssDocument->render();
This can be formatted using an instance of type \Sabberworm\CSS\OutputFormat.
