如何在php文件中更改php.ini设置

Question

i am installing vtiger6 in clients server. I don't have access to php.ini file. I have tried to change some php.ini setting throught my index.php file some settings works fine

ini_set('max_execution_time', 600);
ini_set('log_errors','off');

but i am not able to setup the following

ini_set('error_reporting','E_WARNING ^ E_NOTICE ^ E_DEPRECATED');
ini_set('allow_call_time_pass_reference','1');

and also i need to change the following too i don't know whether this is right or not

ini_set('max_file_uploads',300);
ini_set('memory_limit','240M');
ini_set('max_input_time ',600);

any help will be greatly appreciated.

Answer 1

The reason why error_reporting did not is, you set it's value to the following string. 'E_WARNING ^ E_NOTICE ^ E_DEPRECATED'. But it should not be a string. E_* values are PHP constants and should be used outside quotes like:

ini_set('error_reporting',E_WARNING ^ E_NOTICE ^ E_DEPRECATED);

Also you are using binary XOR (^) between these constants, which is unusual. Suggested value for production environments it is suggested to use E_ALL alone, for debugging. If you want all errors except E_DEPRECATED, you can use E_ALL & ~E_DEPRECATED

Some PHP settings cannot be changed with ini_set. You can check PHP documentation for which variables allow setting on file level. For example, max_file_uploads is only changable from php.ini (documentation)
