php - 尝试设置 XAMPP (Windows) 以并行支持两个 PHP 版本

问题描述

我在包含 PHP 8 的 Windows 10 (xampp-windows-x64-8.0.10-0-VS16) 上成功运行 XAMPP。现在我需要处理一些尚未准备好 PHP 8 的旧项目。找到几篇文章解释了如何设置环境以支持两个版本的 PHP。我按照Is there way to use two PHP versions in XAMPP? ，特别是在标题为“当您可以通过单个 xampp 安装同时使用多个 PHP 版本时为什么在 PHP 版本之间切换？”的答案中，选项 1仅对特定目录使用 PHP 7.4

我无法让它工作。这是我到目前为止所做的：

  1. 从php.net下载 PHP 7.4 (VC15 x64 Non Thread Safe (2021-Sep-21 16:58:34)) ，并将 zip 解压到“xampp”目录下的新目录“php74”，即d:\xamp \php74。
  2. 在 *php74" 中创建文件php.ini，并对其进行修改。
  3. 按照说明编辑了http-xampp.conf文件。

通过此设置（请参阅下面的配置文件），PHP 8 就绪的网站（仍然）正确显示在 brwoser 中。

访问localhost/photos-local-dev/时，我可以看到 Apache 正在尝试为该网站运行 PHP 7.4，因为之前的错误消息...Call to undefined function get_magic_quotes_gpc()...不再显示。因此httpd-xampp.conf中的新指令处于活动状态。

然而，浏览器没有将index.php传递给 PHP 7.4，而是简单地将index.php文件显示为（几乎）纯文本文件（不要看换行符；出于可读性原因，我重新格式化了一点）：

0 && $page['start']>=count($page['items'])) { page_not_found('', duplicate_index_url(array('start'=>0))); } 
trigger_notify('loc_begin_index');//---------------------------------------------- change of image display order 
if (isset($_GET['image_order'])) { if ( (int)$_GET['image_order'] > 0){pwg_set_session_var('image_order', 
(int)$_GET['image_order']); } else {pwg_unset_session_var('image_order'); } redirect( duplicate_index_url( array(),//
nothing to redefine array('start') // changing display order goes back to section first page ) ); } if(isset(
$_GET['display'])) { $page['meta_robots']['noindex']=1; if (array_key_exists($_GET['display'],
ImageStdParams::get_defined_type_map())) {pwg_set_session_var('index_deriv', $_GET['display']); } } 
//-------------------------------------------------------------- initialization // navigation bar $page[
'navigation_bar'] = array(); if (count($page['items']) > $page['nb_image_page']) { $page['navigation_bar'] = 
create_navigation_bar( duplicate_index_url(array(), array('start')), count($page['items']),

在尝试查找问题时，我偶然发现了httpd-xampp.conf中的以下几行：

<IfModule env_module>
    SetEnv MIBDIRS "D:/xampp/php/extras/mibs"
    SetEnv MYSQL_HOME "\\xampp\\mysql\\bin"
    SetEnv OPENSSL_CONF "D:/xampp/apache/bin/openssl.cnf"
    SetEnv PHP_PEAR_SYSCONF_DIR "\\xampp\\php"
    SetEnv PHPRC "\\xampp\\php"
    SetEnv TMP "\\xampp\\tmp"
</IfModule>

#
# PHP-Module setup
#
LoadFile "D:/xampp/php/php8ts.dll"
LoadFile "D:/xampp/php/libpq.dll"
LoadFile "D:/xampp/php/libsqlite3.dll"
LoadModule php_module "D:/xampp/php/php8apache2_4.dll"

如果我停用LoadFile和LoadModule行，然后尝试再次显示 PHP 8 就绪的网站，则浏览器会将index.php显示为文本，如上所示。这证实了这些负载是必不可少的。那么，我可以添加指向 PHP 7.4 模块的相应指令吗？Apache如何区分？但是，唉，模块php7ts.dll，php7apach2_4.dll甚至不存在于 PHP74 目录中？这些必须是 xampp 提供的 PHP 附加组件，因为在官方 zip 文件中找不到它们。

有人真的让这个工作吗？对上述堆栈溢出问答的一些评论似乎表明了这一点。

那么，我错过了什么？

这是httpd-xamp.conf：
