HomeBackend DevelopmentPHP Tutorialapache - LAMP 用 php 的 zip 库,却说找不到 =。=

俺是一个很水的 web 程序猿,基本没写过什么项目。问题一看也很水,但是在网上找了很久,也没找到答案,希望大侠们别喷俺。

环境如下:

  • Archlinux 3.16.3
  • Apache 2.4.10
  • PHP 5.6.0

需求是通过页面选择,将其他地方的 zip 文件下载到服务端,然后解压输出到客户端。在编写过程中有个疑问,用 fwrite 写到 /tmp/xx.zip 的文件对服务端的普通用户不可见。索性用

<code>exec('ls /tmp/*.zip', $result);
print_r($result);
</code>

可以显示出来,而且通过 file_get_contents 之类的方法可以确保文件的确存在。

现在的问题是,在 php.ini 中已经确保开启了 zip 扩展,并在本地执行以下代码也可行:

<code>$zip = zip_open($target);

if($zip) {
    while($entry = zip_read($zip)) {
        echo zip_entry_name($entry) . ': ' .
            zip_entry_filesize($entry) . '/' .
            zip_entry_compressedsize($entry) . ', by' .
            zip_entry_compressionmethod($entry) . "\n";
    }
    zip_close($zip);
}
</code>

注意,是本地执行,即 php file.php,但是放到 Apache 目录中,通过浏览器访问就不行了。错误提示:PHP Fatal error: Call to undefined function zip_open()

本地执行没问题,用 URL 访问说函数不存在,说明 cli 环境和 Apache 用的不是一个 PHP。

找到 cli 环境的 PHP 位置,看是否和 mod_php 位置一致,如果一致,请:

重启 Apache。

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.
