Hi guys! I have this php in my hosting: <html> <head><title>Test email via php</title></head> <body> <?php ini_set('display_errors',1); require_once "Mail.php"; $from = "Sender <[email protected]>"; $to = "Recipient <[email protected]>"; $subject = "This is a test email sent via php"; $body = "This is a test email"; $port = "25"; $host = "mail.informacionabc.org.gt"; $username = "[email protected]"; $password = "projabcpassword123"; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); ?> </body> </html> explorer displays : Warning: require_once(Mail.php): failed to open stream: No such file or directory in E:\web\projabc\smtp\index.php on line 6 Fatal error: require_once(): Failed opening required 'Mail.php' (include_path='.;C:\php\pear') in E:\web\projabc\smtp\index.php on line 6 Should I write some additional path in the require_once command? Or maybe I should copy some pear directory in the project folder? Thank you very much !
