Urgent help "php setttings by phpcode" in_set

[phprock]

I dont have access to php.ini file but as i far i know can change some settings through ini_set function.

How can i change these php settings from php code.

expose_php=Off
display_errors=Off
upload_max_filesize=12MB

I have tried to increase the upload file size limit by add this in my script but no luck.

ini_set("upload_max_filesize","8M");

depending on what php version you are using you wont be able to change upload_max_filesize. expose_php can only be modified in php.ini and display errors takes a long argument, not a string.

see www.php.net/manual/en/ini.php for more
