PHPMailer() isn't working - help?

I am trying to send outgoing emails from my PHP app. Here is the error I get:

“Fatal error: Class ‘PHPMailer’ not found in /usr/share/nginx/templates/webapp.php”

And here is my PHP code for sending the mail, with the require commented out:

//require ( ‘class.phpmailer.php’); $mail = new PHPMailer();
$mail->IsSMTP(); // telling the class to use SMTP $mail->Host = “mail.yourdomain.com”; // SMTP server $mail->SMTPDebug = 0; // enables SMTP debug information (for testing) $mail->SMTPAuth = true; // enable SMTP authentication $mail->SMTPSecure = “tls”; // sets the prefix to the servier $mail->Host = “smtp.gmail.com”; // sets GMAIL as the SMTP server $mail->Port = 587; // set the SMTP port for the GMAIL server <etc…> $mail -> isHTML(true); // ALLOWS HTML EMAIL FORMATTING $mail-> Subject = $emailsubject ; $mail -> Body = $emailbody ; if ($mail->Send() == false ) { die($mail->ErrInfo) ; }

When I include the ‘require’ statement, I get the following error:

Warning: require(class.phpmailer.php): failed to open stream: No such file or directory in /usr/share/nginx/templates/webapp.php

Help? Thanks!!
