shall i enable this php function escapeshellarg() in .htaccess . This php function is in the disable list in php.ini of the server for some security reasons.
So please suggest that how shall i enable it from the .htaccess file. or give me alternative solutions.
You can't override disable_functions in a .htaccess file as this setting is PHP_INI_SYSTEM only.
You could write your own flavour of escapeshellarg() but if this is disabled, exec() and system() are probably too, so this is a bit pointless.
You probably are on a shared server and would need to go either VPS or Dedicated to set your very own PHP configuration.
