  2. Navigate to the file in your browser and confirm the current php version before the update.
  3. Download and extract the current version of PHP from here and extract it to C:\PHP\VerNo.\
  4. In the new directory locate php.ini-production, copy and rename it php.ini in the same location.
  5. Open the current php.ini in (path is visable here: IIS>Fast CGI Settings) > Copy the bottom portion begining with: [WebPIChanges] to end > add it to the botom of the php.ini file created in step two.
  6. Download WinCache Extension from here or here and extract it to C:\PHP\VerNo.\ext\
  7. Open a text editor and update the version number in the script below (7.3.4) then run it in CMD

%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/fastCgi /[fullPath='C:\PHP\7.3.4\php-cgi.exe'].instanceMaxRequests:10000
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/fastCgi /+"[fullPath='C:\PHP\7.3.4\php-cgi.exe'].environmentVariables.[name='PHP_FCGI_MAX_REQUESTS',value='10000']"

Verify the update is complete by refreshing the about.php from step two & checking all the sites. To role back to the previous version you can restore the path in the script above and run it.
