First, put all CSS in a directory, and then create an empty CSS file named css. php in this directory (except for the suffix ).
Then put the edge code in the PHP file:
| The code is as follows: |
Copy code |
<? Php
Header ('content-type: text/css ');
Ob_start ("compress ");
Function compress ($ buffer ){
$ Buffer = preg_replace ('! /* [^ *] ** + ([^/] [^ *] ** + )*/! ', '', $ Buffer );
$ Buffer = str_replace (array ("rn", "r", "n", "t", ''),'', $ buffer );
Return $ buffer;
}
/* Include('colorpicker.css ');
Include('jquery-ui.css ');
Include('style.css ');
Include('switchery.min.css ');*/
Foreach (glob ("*. css") as $ filename) include $ filename;
Ob_end_flush (); The code for introducing the CSS file is replaced with the PHP file, for example:
<Link rel = 'stylesheet 'id = 'style-css' href = '/css. Php' type = 'text/css' media = 'all'/>
|
Compress multiple css into one css
| The code is as follows: |
Copy code |
<? Php
/*
Compress multiple CSS files into one and cache for an hour. Use the same code for Javascript, but replace below "text/css" with "text/javascript" and of course make sure you include. js files instead of. css ones.
*/Www.111cn.net
Ob_start ("ob_gzhandler ");
Header ("Content-type: text/css; charset: UTF-8 ");
Header ("Expires:". gmdate ("D, d m y h: I: s", time () + 60*60). "GMT "); Include('somefile.css ');
Echo "nn ";
Include('anotherfile.css ');
Echo "nn "; Ob_flush (); |
The following describes the JavaScript and css functions that can be compressed.
| The code is as follows: |
Copy code |

The PHP file contains all the compressed CSS code, and all CSS files in the CSS directory can be automatically introduced without modifying the PHP file when creating the CSS file.
