PHP handlers are Apache modules that contain libraries for the Apache web server to use when running PHP code. Apache's PHP handlers are configured in the /etc/apache2/conf.d/php.conf configuration file. cPanel & WHM come with six PHP handlers. Apache handles PHP requests differently based on the files and implementation of each handler.

  1. CGI

  2. DSO

  3. FastCGI Process Manager (FPM)

  4. FCGI daemon (FCGId)

  5. LSAPI

Step 1. Login into the server using SSH.

Step 2. Run the following command as per your requirement.

To list current handler:

To list all available PHP handlers on the server

To change the current PHP handler to “DSO”

# /usr/local/cpanel/bin/rebuild_phpconf 4 dso none 1

To change the current PHP handler to “SuPHP”

# /usr/local/cpanel/bin/rebuild_phpconf 5 none suphp 1

To change the current PHP handler to CGI
