Parse css and generate file with PHP-CSS-PARSE

Question

I'm trying to parse a CSS file with the Raphael Schweikert's lib Sabberworm\PHP-CSS-PARSE

But I'm blocked with object manipulations. What I'm trying to do is to convert this css file:

.header {
  background: #000;
}

.footer, .wrapper {
  background: #ebebeb;
}

In a PHP/JSON like format:

 '.header'  => "background: #000;",
 '.footer'  => "background: #ebebeb;",
 '.wrapper' => "background: #ebebeb;"

What i did:

<?php

require 'vendor/autoload.php';
$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('style.css'));
$oCssDocument = $oCssParser->parse();
$selectors=$oCssDocument->getAllRuleSets();
...

but how to loop after ? The structure of the object is not easy for a neewbe like me...

Answer 1

(This should be a comment, but with the code this is better readable).

I'm not familiar with PHP-CSS-PARSE, but I have one observation: I would assume

.footer .wrapper {
  background: #ebebeb;
}

would become '.footer .wrapper' => "background: #ebebeb;".

If you want

'.footer'  => "background: #ebebeb;",
'.wrapper' => "background: #ebebeb;"

then the CSS would have to be

.footer, .wrapper {
  background: #ebebeb;
}

(notice the comma) or have to have separate rules.

I was lazy yesterday...

<?php

require 'vendor/autoload.php';

$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('style.css'));
$oCssDocument = $oCssParser->parse();

foreach ($oCssDocument->getAllRuleSets() as $oRuleSet) {

    $sSelector = $oRuleSet->getSelectors();
    foreach ($sSelector as $currentSelector) {
            $sSelector = $currentSelector->getSelector();
            echo "\r\n\"$sSelector\" = \"";
            foreach( $oRuleSet->getRules() as $sRules) {
                echo "$sRules ";
            }
            echo "\"";
    }
}

wich renders

".header" = "background: #000; "
".footer" = "background: #ebebeb; "
".wrapper" = "background: #ebebeb; "
