I hope it will be helpful to answer the doubts about "how to use JS and CSS optimization tools Minify". Next, please follow the editor to study!

Code for merging and compressing multiple JS and CSS files

HTML:

The copy code is as follows:

PHP:

The copy code is as follows:

/ / output JS

Header ("Content-type:Application/x-javascript; Charset: utf-8")

If (isset ($_ GET)) {

$files = explode (",", $_ GET ['get'])

$str =''

Foreach ($files as $key = > $val) {

$str. = file_get_contents ($_ GET ['path']. $val)

}

$str = str_replace ("\ t", "", $str); / / clear spaces

$str = str_replace ("\ r\ n", "", $str)

$str = str_replace ("\ n", "", $str)

/ / Delete single-line comments

$str = preg_replace ("/\ s * [a-zA-Z0-9 _\ x7f -\ xff] [a-zA-Z0-9 _\ x7f -\ xff] * /", ", $str)

/ / Delete multiline comments

$str = preg_replace ("/\ * [^\ /] *\ *\ / s", "", $str)

Echo $str

}

/ / output CSS

Header ("content-type:text/css; charset: utf-8")

If (isset ($_ GET)) {

$files = explode (",", $_ GET ['get'])

$fc =''

Foreach ($files as $key = > $val) {

$fc. = file_get_contents ($_ GET ['path']. $val. ".css")

}

$fc = str_replace ("\ t", "", $fc); / / clear spaces

$fc = str_replace ("\ r\ n", "", $fc)

$fc = str_replace ("\ n", "", $fc)

$fc = preg_replace ("/\ * [^\ /] *\ *\ / s", "", $fc)

Echo $fc

}

It's just a simple prototype, no encapsulation. In addition, the merged files remember to cooperate with the cache

II. How to use Minify

1. Download the latest version of Minify from code.google.com/p/minify/ and extract it, and copy the "min" folder together with its contents to the DOCUMENT_ROOT directory (that is, websites and directories).

You can change the folder name "min"

2. Configure the g parameter in "min/groupsConfig.php"

The copy code is as follows:

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:

The following numbers can be marked with the update date, and "min" corresponds to the name in step 1.

4. For 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 debug mode, and then turn off the debug mode after the development is completed. You can use the firebug of Firefox to view it.

The copy code is as follows:

$min_allowDebugFlag = true
