how can i disable safe mode for php on web server?

Question

I am using wkhtmltopdf for making a pdf of a page. My code executes the shell to run a command using this wkhtmltopdf library. Everything works fine in my wamp server but when the code runs on my web-server it does not work and gives the following error:

Warning: shell_exec() has been disabled for security reasons in /home/pssptech/public_html/.../cert.php on line 272

I think that the php is running on safe mode on the server that's why the shell execution is disabled. But the main problem is I am unable to find the php.ini file on my remote web-server.
Can you tell me where can I find the config file so that I can disable the safe mode?
Thanks in advance.

Edit your php.ini and set the variable safe_mode to off.

safe_mode = Off

To find php.ini in linux run

find / -name php.ini -print

Can you please tell me from where can I run this command on my remote web-server? – Bushra Shahid Nov 01 '12 at 10:56
You should run this command in terminal. What kind of access do you have in your server? – Hex Nov 01 '12 at 11:00
The server is a shared one so I only have ftp access. – Bushra Shahid Nov 01 '12 at 11:03
Can you try to add "php_value safe_mode off" in your .htaccess and check if it helps? – Hex Nov 01 '12 at 11:15
I just tried it and it gave me "Internal Server Error" (error code:500) – Bushra Shahid Nov 01 '12 at 11:29

@user1767434 then you'll need to ask your host to change it for you, and if they won't, then you'll need to change to a different host. – DerfK Nov 01 '12 at 13:05

In current version of PHP (7.1.8), there is no more `safe_mode` option. There is only `sql.safe_mode`. Is this the same? – 71GA Aug 08 '17 at 16:48
