CSS merging with PHP

Question

I found this on a website,

css_loader.php

Answer 1

hey have you checked if your server appends a few lines to your code (for example an analytics code) . if so you must add a rule in .htaccess that stops the server for adding lines to your code. this can be done by adding this to .htaccess - "php_value auto_append_file none" without quotes of course . i hope this helps

Answer 2

I wrote this class for such needs, it can render the output and compress it, later i can add write a file of the end results, link here

Stoney has shown you your error .... now for a more improved version

        header('Content-type: text/css');
        ob_start("compress");
        function compress($buffer) {
            /* remove comments */
            $buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer);
            /* remove tabs, spaces, newlines, etc. */
            $buffer = str_replace(array("\r\n", "\r", "\n", "\t", '  ', '    ', '    '), '', $buffer);
            return $buffer;
        }

        /* your css files */
        include('main.css');
        include('menu.css');
        include('content.css');
        ob_end_flush();

Answer 4

You have an mistake in your code, here's the correct code:

<?php
// First of all send css header
header("Content-type: text/css");

// Array of css files
$css = array(
    'main.css',
    'menu.css',
    'content.css'
);

// Prevent a notice
$css_content = '';

// Loop the css Array
foreach ($css as $css_file) {
    // Load the content of the css file 
    $css_content .= file_get_contents($css_file);
}

// print the css content
echo $css_content;
?>

And I hope the files are in the same folder. Perhaps you should use __DIR__ or dirname(__FILE__) to get the relative path to your files.

<?php

// Array of css files
$css = array(
 'first.css',
 'second.css'
);

$mergeCSS = "";
// Loop the css Array
foreach ($cssas $css_file) {
    // Load the content of the css file 
    $mergeCSS.= file_get_contents($css_file);
}

// Remove comments also applicable in javascript
$mergeCSS= preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $mergeCSS);

// Remove space after colons
$mergeCSS= str_replace(': ', ':', $mergeCSS);

// Remove whitespace
$mergeCSS= str_replace(array("\n", "\t", '  ', '    ', '    '), '', $mergeCSS);

//Generate Etag
$genEtag = md5_file($_SERVER['SCRIPT_FILENAME']);

// call the browser that support gzip, deflate or none at all, if the browser doest      support compression this function will automatically return to FALSE
ob_start('ob_gzhandler');

// call the generated etag
header("Etag: ".$genEtag); 

// Same as the cache-control and this is optional
header("Pragma: public");

// Enable caching
header("Cache-Control: public ");

// Expire in one day
header('Expires: ' . gmdate('D, d M Y H:i:s', time() + 86400 ) . ' GMT');

// Set the correct MIME type, because Apache won't set it for us
header("Content-type: text/javascript");

// Set accept-encoding
header('Vary: Accept-Encoding');

// Write everything out
echo($mergeCSS);

?>

This code also compatible for merging javascript
