How to concatenate a variable

[reddymade]

I would like to show the "friend_name" variable value after the "Hey!" which is $subject.

Should i use ampersand to concatenate.

$cont_arr = array(
"friend_name" => $name,
"friends_count" => $friends_count,
"location" => $location,
);

$subject = "Hey!";

SendMail($email, $my_email, $subject, $cont_arr, "referral_mail");

Thank you very much for the information.

$subject = "Hey!" . $cont_arr['friend_name'];

Concatenation is done in one of two ways. Either with a dot (as demonstrated above) or with a comma. The most common is the dot (so as to not confuse you with function elements).

You could also add or append strings to variables using the .= syntax:

$subject = "Hey!";
$subject .= $cont_arr['friend_name'];
