            $header_str = &#39;Content-Type:   text/javascript&#39;;
        } elseif (stripos($files[0], &#39;.css&#39;) !== false) {

    foreach($files as $key=>$value) {
        require_once($value);
    }
    // 改回当前脚本的执行路径
    chdir($old_dir);
}
?>

How to use

The code is as follows:

"a.js"、"b.js"和"../c.js"是待合并的JS文件，将其合并为base.js.php，则base.js.php中的代码如下：
<?php
    import_static(array(
        &#39;a.js&#39;,
        &#39;b.js&#39;,
        &#39;../c.js&#39;,
        &#39;../moduleB/all.js.php&#39;    // 也可引用.php文件
    ), FILE);
?>

Use can be imported.

Before the product goes online, use batch process files to process, mainly doing two aspects of work
1. Output "*.js.php" to "*.js" file , and delete "*.js.php". Command line: php *.js.php > *.js
2. Replace the reference to "*.js.php" in the HTML page with "*.js". preg_replace()

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