max_input_time: Set this time to limit the amount of time a script can parse input data like POST, GET and file uploads.
max_input_vars: You can limit how much input variables are allowed per request to prevent DDoS attack.
memory_limit: With this field, you can limit how much memory a script can use. This limitation makes sure that poorly written scripts do not eat up all the available memory of a server. It should be larger than post_max_size
post_max_size: This sets a maximum amount of post data allowed. It also affects file uploading so it should be larger than upload_max_filesize.
session.gc_maxlifetime: The maximum amount of time while the session data can live and after that, it will be gotten rid of as “garbage”
upload_max_filesize: The maximum size of a file allowed for upload on the website.
zlib.output_compression: This option compresses the webpages when the server receives “Accept-Encoding: gzip” or “deflate” header command.

Changing PHP version Using Cloudlinux “Select PHP Version” or “PHP Selector” from cPanel
You can also change the PHP version for your websites using the “Select PHP Version” from cPanel. The benefit of using the “Select PHP Version” option over the “Multiphp Manager” is that here you can also select which PHP extensions you want to enable or disable for your websites. You can easily enable or disable PHP extensions from the “Extensions” tab inside “Select PHP Version”. But the disadvantage is that you can not select an individual PHP version for all of your domain or subdomains using the “Select PHP Version” option. The PHP version that you select here will apply to all the websites that you have selected to use with this tool. Here is how to set it:
- After logging into the cPanel, go to the “Select PHP version”
- Select the PHP version that you want to set for your websites.
- On the bottom of the page, you will see a list of your domains and subdomains in that cPanel. If those domains or subdomains are not already using “PHP Selector”, then click on the “Use PHP Selector” button beside the domain or subdomain name.
That’s it! Your website is now using the PHP version that you have selected using the PHP Selector or “Select PHP Version” option.
Please keep in mind that, if your website PHP version has been defined by “Multiphp Manager” and it is using a default PHP version (Displayed on Step 4 of using MultiPHP manager), then you will not be set it to use “PHP Selector”. In that case, you will need to change the PHP version from MultiPHP Manager to some other version then the “System PHP Version” and after that, you can use that domain with “PHP Selector”.
