Hi Emylin Manuela,
Thanks for contacting Syncfusion Support.
You cannot change Register_argc_argv after being registered, i.e. Register_argc_argv cannot be changed after initial load using ini_set() method as they have already been registered. To change, you need to copy your php.ini file in the hosting site. The PHP configuration is usually dependent on the hosting provider; so you need to make the changes in the hosting environment.
Refer to following documentations:
