@gizmola, Yes, seems I need to learn about both namespaces and more about classes. I'm an old school layman and really not up to speed. Thanks for the advice. ... I have resolved my issue by just simply not using a function but I understand that I've missed a lot. I mean, for heaven's sake, I'm still on a Macromedia Dreamweaver... ;-). So VsCode, and a lot of reading and tutorials it will be when I have time. Consider the issue closed. Thank you all.

Closing in on the problem. This works: <?php // Start the session // session_start(); include 'testfunctions.php'; ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; // Include PHPMailer autoloader or include necessary PHP files require_once 'PHPMailer/src/PHPMailer.php'; require_once 'PHPMailer/src/SMTP.php'; require_once 'PHPMailer/src/Exception.php'; // Create a new PHPMailer instance $mail = new PHPMailer(true); // Enable exceptions try { // SMTP configuration $mail->isSMTP(); $mail->Host = 'mail.qss.mgo.mybluehost.me'; // Your SMTP server host $mail->SMTPAuth = true; $mail->Username = 'xxxxx'; // Your SMTP username $mail->Password = 'xxxxx'; // Your SMTP password $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption $mail->Port = 587; // TCP port to connect to // Sender and recipient addresses $mail->setFrom('xxx.com', 'Your Name'); // Sender's email address and name $mail->addAddress('xxx.com', 'Recipient Name'); // Recipient's email address and name // Email content $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'Test Email'; $mail->Body = 'This is a test email sent using PHPMailer'; // Send the email if ($mail->send()) { echo 'Email sent successfully!'; } else { echo 'Error: Email not sent.'; } } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } echo "1<br>"; // $dummy=func(); echo "2<br>"; exit; ?> This does not!: <?php // Start the session // session_start(); include 'testfunctions.php'; ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); function func() { // the whole thing unchaged inide a function use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; // Include PHPMailer autoloader or include necessary PHP files require_once 'PHPMailer/src/PHPMailer.php'; require_once 'PHPMailer/src/SMTP.php'; require_once 'PHPMailer/src/Exception.php'; // Create a new PHPMailer instance $mail = new PHPMailer(true); // Enable exceptions try { // SMTP configuration $mail->isSMTP(); $mail->Host = 'mail.qss.mgo.mybluehost.me'; // Your SMTP server host $mail->SMTPAuth = true; $mail->Username = 'xxxxx'; // Your SMTP username $mail->Password = 'xxxxx'; // Your SMTP password $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption $mail->Port = 587; // TCP port to connect to // Sender and recipient addresses $mail->setFrom('xxx.com', 'Your Name'); // Sender's email address and name $mail->addAddress('xxx.com', 'Recipient Name'); // Recipient's email address and name // Email content $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'Test Email'; $mail->Body = 'This is a test email sent using PHPMailer'; // Send the email if ($mail->send()) { echo 'Email sent successfully!'; } else { echo 'Error: Email not sent.'; } } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } } // End of function echo "1<br>"; $dummy=func(); // calling the function echo "2<br>"; exit; ?> Just throws a 500 Error Any Ideas?

Ok, does not work either... will recap and reformulate the problem more simply: I have a WORKING script: phpmailer.php, see the first code posted in this thread. I am enclosing the whole script in a function: func() { the whole script unchaged goes here } then I am calling the function: <?php // Start the session session_start(); ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); require 'testfunctions.php'; echo "1<br>"; $dummy=func(); echo "2<br>"; exit; ?> and I get this error: Parse error: syntax error, unexpected token "use" in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php on line 3 It does not work if I change "use" to require_once. Then I get this error: Fatal error: Uncaught Error: Undefined constant "PHPMailer\PHPMailer\PHPMailer" in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php:3 Stack trace: #0 /home2/qssmgomy/public_html/parque-carolina.com/Y/test.php(12): func() #1 {main} thrown in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php on line 3 Please help

Maybe I misunderstood. Will try putting the use statements back into the function and then changing use to require_once... Will report soon. Out for coffee just now.

I am sorry but that does not work. It is quite confusing. You mention the "use statement not being sufficient (its in the calling script) but then in the code you supplied you changed the require into require_once in the function. Still I tested both variations. None worked. Error if I change the require statement to require_once in the function script as you did in the code you supplied: Fatal error: Uncaught Error: Class "PHPMailer" not found in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php:15 Stack trace: #0 /home2/qssmgomy/public_html/parque-carolina.com/Y/test.php(15): func() #1 {main} thrown in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php on line 15 and if I Change the use stetement in the calling script as I assume you intended: Fatal error: Uncaught Error: Undefined constant "PHPMailer\PHPMailer\PHPMailer" in /home2/qssmgomy/public_html/parque-carolina.com/Y/test.php:8 Stack trace: #0 {main} thrown in /home2/qssmgomy/public_html/parque-carolina.com/Y/test.php on line 8 So neither works...

I am trying to use PHPMailer as a function. I mean I want to call the PHPMailer script "off the shelf and working" see code phpmailer.php from another script by just simply putting the whole script phpmailer.php into a function func($somearray) { ... } and then call and use it when I need it. But I cant get it to work. phpmailer.php, the working script is here: <?php ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; // Include PHPMailer autoloader or include necessary PHP files require 'PHPMailer/src/PHPMailer.php'; require 'PHPMailer/src/SMTP.php'; require 'PHPMailer/src/Exception.php'; // Create a new PHPMailer instance $mail = new PHPMailer(true); // Enable exceptions try { // SMTP configuration $mail->isSMTP(); $mail->Host = 'mail.qss.mgo.mybluehost.me'; // Your SMTP server host $mail->SMTPAuth = true; $mail->Username = 'xxxxx'; // Your SMTP username $mail->Password = 'xxxxx'; // Your SMTP password $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption $mail->Port = 587; // TCP port to connect to // Sender and recipient addresses $mail->setFrom('xxxxx', 'Your Name'); // Sender's email address and name $mail->addAddress('xxxxx', 'Recipient Name'); // Recipient's email address and name // Email content $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'Test Email'; $mail->Body = 'This is a test email sent using PHPMailer'; // Send the email if ($mail->send()) { echo 'Email sent successfully!'; } else { echo 'Error: Email not sent.'; } } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } ?> First issue was that the code section: use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; makes trouble when inside the function. So I put it into my calling script at the top. So my calling script is test.php: <?php // Start the session session_start(); ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; require 'testfunctions.php'; echo "1<br>"; $dummy=func(); echo "2<br>"; exit; ?> and the rest is in testfunctions.php: <?php function func() { ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); // 3 lines taken from here... // Include PHPMailer autoloader or include necessary PHP files require 'PHPMailer/src/PHPMailer.php'; require 'PHPMailer/src/SMTP.php'; require 'PHPMailer/src/Exception.php'; // Create a new PHPMailer instance $mail = new PHPMailer(true); // Enable exceptions try { // SMTP configuration $mail->isSMTP(); $mail->Host = 'mail.qss.mgo.mybluehost.me'; // Your SMTP server host $mail->SMTPAuth = true; $mail->Username = 'xxxxx'; // Your SMTP username $mail->Password = 'xxxxx'; // Your SMTP password $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption $mail->Port = 587; // TCP port to connect to // Sender and recipient addresses $mail->setFrom('xxxxx', 'Your Name'); // Sender's email address and name $mail->addAddress('xxxxx', 'Recipient Name'); // Recipient's email address and name // Email content $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'Test Email'; $mail->Body = 'This is a test email sent using PHPMailer'; // Send the email if ($mail->send()) { echo 'Email sent successfully!'; } else { echo 'Error: Email not sent.'; } } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } } ?> so now I am getting a (not found) message after my 1 is printed to screen... 1 Fatal error: Uncaught Error: Class "PHPMailer" not found in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php:15 Stack trace: #0 /home2/qssmgomy/public_html/parque-carolina.com/Y/test.php(15): func() #1 {main} thrown in /home2/qssmgomy/public_html/parque-carolina.com/Y/testfunctions.php on line 15 Of course the two files testfunctions.php and test.php are right next to one another in the same folder as the working file phpmailer.php. Any help greatly appreciated.
