You can modify your PHP limits and settings from MultiPHP INI Editor in cPanel. You can go there by logging in to cPanel and going to MultiPHP INI Editor from the software section.
Select the website location that you want to modify.
display_errors: Enable this if you want to display the error messages to the end-user. By default, it is disabled.
max_execution_time: With this, you can set how much time a script can run before it is terminated. The time is set in seconds.
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.
You can change those values to set them according to your needs.
