In order to reduce HTTP requests, we often need to merge and compress multiple JS and CSS files. Below is a record of the PHP source code that implements this function and the use of the open source project Minify on the Internet
1. For the code to merge and compress multiple JS and CSS files, please refer to
1. Quickly merge JS and CSS files with one command
2. PHP merges multiple JS and CSS files to reduce HTTP requests (prototype)
2. How to use Minify
1. Download the latest version of Minify from code.google.com/p/minify/ and unzip it. Copy the "min" folder and its contents to the DOCUMENT_ROOT directory (i.e. website and directory).
You can modify the folder name "min"
2. Configure the g parameter in "min/groupsConfig.php"
return array(
// 'js' => array('//js/file1.js', '//js/file2.js'),
// 'css' => ; array('//css/file1.css', '//css/file2.css'),
);
3. Just quote it in the web page as follows:
<script type="text/javascript" src="/min/g=js&20140519"></script>The number after
can be marked with the update date, and "min" corresponds to the name in step 1.
4. Performance optimization, please refer to code.google.com/p/minify/wiki/CookBook
Note:
1. You need to enable the rewrite_module module in httpd.conf
2. During the development process, you can turn on the debugging mode. After the development is completed, turn off the debugging mode. You can use the firebug of Firefox browser to view
