Usage

• Exmple 1

!/usr/bin/php

$path = "./sample.css"; $original_data = @file_get_contents($path); $scss_optimizer = new sCSSOptimizer($original_data); $optimized_data = $scss_optimizer->getOptimized(); $compression_rate = $scss_optimizer->getCompressionRate(); //now you can save this optimized data to new css file. //or simply you can print that. print($optimized_data);

• Example 2

!/usr/bin/php

$css1 = file_get_contents("./sample1.css"); $css2 = file_get_contents("./sample2.css"); //if you want to compile 2 css files than don't optimize them separatly. //Instead you can do this in a very simple way. $css = $css1.$css2; //join them $scss_optimizer = new sCSSOptimizer($css); //and than parse them $compiled_css = $scss_optimizer->getOptimized();
