在 Windows 中安装 pthread 时遇到问题

Question

PHP 版本： 7.4.5

我正在运行 PHP 的线程安全版本，因为在执行 php -i|findstr "Thread" 之后我得到：

Thread Safety => enabled
Thread API => Windows Threads

我从https://windows.php.net/downloads/pecl/releases/pthreads/3.1.6/ 下载了最新版本的 pthreads (3.1.6)（我尝试了 32 位和 64 位版本）。

我将pthreadVC2.dll 文件放在我的php\ 目录中，将php_pthreads.dll 文件放在我的php\ext\ 目录中，并将extension=php_pthreads.dll 行添加到我的php.ini 文件中

然后通过命令行运行任何 php 命令后（在我的例子中，php -v）我在尝试 32 位版本时在控制台中得到以下信息：

PHP Warning:  PHP Startup: Unable to load dynamic library 'php_pthreads.dll' (tried: C:\xampp\php\ext\php_pthreads.dll (%1 is not a valid Win32 application.), C:\xampp\php\ext\php_php_pthreads.dll.dll (The specified module could not be found.)) in Unknown on line 0

Warning: PHP Startup: Unable to load dynamic library 'php_pthreads.dll' (tried: C:\xampp\php\ext\php_pthreads.dll (%1 is not a valid Win32 application.), C:\xampp\php\ext\php_php_pthreads.dll.dll (The specified module could not be found.)) in Unknown on line 0

尝试 64 位版本时出现此错误：

PHP Warning:  PHP Startup: Unable to load dynamic library 'php_pthreads.dll' (tried: C:\xampp\php\ext\php_pthreads.dll (The specified procedure could not be found.), C:\xampp\php\ext\php_php_pthreads.dll.dll (The specified module could not be found.)) in Unknown on line 0

有什么想法吗？

如果有人遇到这种情况，解决这个问题的方法是修复我的php.ini 文件中的extension_dir 设置，以便实际从同一目录中的ext 文件夹中提取。该行已被注释掉，所以我认为它的默认设置是尝试从 C:\php\ext 获取扩展名。
