I'm looking to add this to my framework to optimise it further. I don't want to use a plugin and I want the code to be as light weight as possible. This is the code I have so far. This works if I only call "style.css" but if I call the other files it doesn't minify the files. I'm getting the same with the js file I have. It removes the white space but it doesn't fully minify the file. Hope someone can help. Thanks
<?php
$dev_master_root = dirname(dirname(dirname(dirname(dirname(__FILE__)))));
if ( file_exists( $dev_master_root.'/wp-load.php' ) ) {
require_once( $dev_master_root.'/wp-load.php' );
} elseif ( file_exists( $dev_master_root.'/wp-config.php' ) ) {
require_once( $dev_master_root.'/wp-config.php' );
}
/* Add your CSS files to this array (THESE ARE ONLY EXAMPLES) */
$cssFiles = array(
"../style.css",
"global.css",
"slicknav.css"
);
$buffer = "";
foreach ($cssFiles as $cssFile) {
$buffer .= file_get_contents($cssFile);
}
// Remove comments
$buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer);
// Remove space after colons
$buffer = str_replace(': ', ':', $buffer);
// Remove whitespace
$buffer = str_replace(array("
", "", "
", "\t", ' ', ' ', ' '), '', $buffer);
// Enable GZip encoding.
ob_start("ob_gzhandler");

// Set the correct MIME type, because Apache won't set it for us

// Write everything out
echo($buffer);

This is the output when only style.css is called using the minify file. i.e when I remove "global.css" and "slicknav.css"
h1,h2,h3,h4,h5,h6 {}p {}#dev-master-main-container {}#dev-master-header-container {background:#fff;}#dev-master-content-container {}#dev-master-footer-container {background:#000026;}#dev-master-footer-content {}@media screen and (max-width :1180px) {}@media screen and (max-width :960px) {}@media screen and (max-width :768px) {}@media screen and (max-width :524px) {}
So in the code above, this is only style.css but you can see all comments etc are being stripped. It's super light weight because all the foundation styles are called from global.css
I have just noticed the spaces in this code which I would also like to remove. I thought the string above would have done that...?
Let me know if you need any more info. Thanks again
