How do I find my $sendmail variable?

[jovigirl]

This might be a weird question, but I have no idea on how to find my $sendmail variable for PHP from my web host. Where can this information be found? I am just learning PHP. Sorry if it's a dumb question. Thanks!

You could always look at the output from phpinfo(), that will tell you what the sendmail setting is in the php.ini.
