HomeBackend DevelopmentPHP TutorialPHP合并静态文件详解_PHP

配置PHP.ini

更改配置项(必须)auto_prepend_file = "C:\xampp\htdocs\auto_prepend_file.php"

更改配置项(可选)allow_url_include = On

auto_prepend_file.php文件内容

代码如下:


/**
 * 引入static文件
 * @param {array|string} 相对路径
 * @param {string} 当前执行脚本所在的路径__FILE__
 *
 */
function import_static($files, $path=NULL){
    // 更改当前脚本的执行路径
    $old_dir = getcwd();
    $tmp_dir = (isset($path)) ? dirname($path): dirname(__FILE__);
    chdir($tmp_dir);
    // 整理包含文件
    if (!is_array($files)) {
        $tmp = array();
        $tmp[] = $files;
        $files = $tmp;
    }
    // 发送头信息
    if (isset($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);
        }
    }
    // 引入包含文件
    foreach($files as $key=>$value) {
        require_once($value);
    }
    // 改回当前脚本的执行路径
    chdir($old_dir);
}
?>

使用方法

代码如下:


"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:
    import_static(array(
        'a.js',
        'b.js',
        '../c.js',
        '../moduleB/all.js.php'    // 也可引用.php文件
    ), __FILE__);
?>

在HTML页面中使用即可引入。

产品上线前,使用批处理文件进行处理,主要做两方面的工作
1.将"*.js.php"输出到"*.js"文件,并删除"*.js.php"。命令行:php *.js.php > *.js
2.将HTML页面中对"*.js.php"的引用替换为"*.js"。preg_replace()

PS:import_static函数解决了PHP中include()处理相对路径的问题。

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
