 *

 */

function import_static($files, $path=NULL){

    //  Change the execution path of the current script 

    $old_dir = getcwd();

    $tmp_dir = (isset($path)) ? dirname($path): dirname(__FILE__);

    chdir($tmp_dir);

    //  Organize include files 

    if (!is_array($files)) {

        $tmp = array();

        $tmp[] = $files;

        $files = $tmp;

    }

    //  Send header information 

    if (isset($files[0])) {

        if (stripos($files[0], '.js') !== false) {

            $header_str = 'Content-Type:   text/javascript';

        } elseif (stripos($files[0], '.css') !== false) {

            $header_str = 'Content-Type:   text/css';

        }

        if (!ob_get_contents()) {

            header($header_str);

        }

    }

    //  Introducing an include file 

    foreach($files as $key=>$value) {

        require_once($value);

?>

Usage

"a.js" , "b.js" And "../c.js" Is to be merged JS File, merge it into a base.js.php , then base.js.php The code in: 

<?php

    import_static(array(

        'a.js',

        'b.js',

        '../c.js',

        '../moduleB/all.js.php'    //  Can also be referenced .php Documents 

    ), __FILE__);

?>

Use in the HTML page < script type="text/javascript" src="base.js.php" > < /script > Can be introduced.

Before the product goes online, batch files are used for processing, which mainly does two aspects of work
1. Output "*. js. php" to the "*. js" file and delete "*. js. php". Command line: php *. js. php & gt *.js
2. Replace the reference to "*. js. php" on the HTML page with "*. js". preg_replace ()

The PS: import_static function solves the problem of include () handling relative paths in PHP.
