Exec function solution

Exec function exec (& quot;/usr/bin/mysqldump-H' 210. 14.65.107 '-uroot-ppsswdAM | gzip & gt;/var/www/html/s/dase. SQL .gz & quot;); this code is used in the linu exec function.
Exec ("/usr/bin/mysqldump-h '2017. 14.65.107 '-uroot-ppsswd AM | gzip>/var/www/html/s/dase. SQL .gz ");

On the linux server, I directly connected the server to execute this php code using php/var/www/html/s/2. php.

However, in windows, I use a url request to execute this php script without any results. I don't know what the class is?


------ Solution --------------------
No permissions or insufficient permissions
------ Solution --------------------
Permission issues: the user executing php on the terminal is different from the user executing url access, so the permissions are different.
You must grant the server user the permission to run the command.
