問題：使用Apache2.4配置php7.0.6和php7.2.1，php7.0.6可以啟動，而php7.2.1無法啟動。 httpd.conf配置參數如下： <IfDefine php7.0.6> LoadModule php7_module "C:/php7.0.6/php7apache2_4.dll" PHPIniDir "C:/php7.0.6" </IfDefine> <IfDefine php7.2.1> LoadModule php7_module "C:/php7.2.1/php7apache2_4.dll" PHPIniDir "C:/php7.2.1" </IfDefine> <IfModule mime_module> TypesConfig conf/mime.types AddType application/x-httpd-php .php .inc </IfModule> CMD執行安裝服務命令的結果如下： C:\Apache24\bin>httpd.exe -k install -n "Apache2.4_PHP7.2.1" -D php7.2.1 Installing the 'Apache2.4_PHP7.2.1' service The 'Apache2.4_PHP7.2.1' service is successfully installed. Testing httpd.conf.... Errors reported here must be corrected before the service can be started. CMD測試安裝好像也是OK的： C:\Apache24\bin>httpd.exe -n "Apache2.4_PHP7.2.1" -t Syntax OK 但是創建的Apache2.4_PHP7.2.1服務無法啟動，error.log文件內有如下的錯誤記錄： [Tue Jan 09 10:51:37.960749 2018] [core:warn] [pid 12396:tid 604] AH00098: pid file C:/Apache24/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run? PHP擴展的extension全部都是注釋狀態的，PHP.ini文件是初始狀態的，只修改了extension_dir。
