variable in an email

mail() function that is

[coolo]

So, say I want to send an automatic email using php. And say I want the content of the email to be personal. I would need a variable (say the person's name) in the message of the email. Would this work?

example:
$name = "Roger";
$message = "Dear $name, thanks for signing up.";

Assuming you put the $message variable in the right spot in the mail function would the email message display the value of the variable?

$name = "Roger";
$message = "Dear ".$name.", thanks for signing up.";

mail("[e-mail]","Subject","$message","From: [e-mail]");
