PHP Parse error: syntax error, unexpected token "use"

[DrWilliamHobbs]

Hi - i got these error in the php_error_log:

PHP Parse error: syntax error, unexpected token "use" in /opt/lampp/htdocs/....

The site isnt loading properly and i used only your snippet:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
    

require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';

I use xampp on linux to test something with php version 8.2.12

A syntax error on that means that you're not using PHP 8.2, but something very old that doesn't support namespaces, which were introduced in PHP 5.3. I suggest you write a script containing <?php phpinfo(); to double check your version.

[DrWilliamHobbs]

Ive double checked it: Same as before....

PHP Version 8.2.12 Build Date Nov 25 2023 08:05:53

This isn't something specific to PHPMailer. Try seeing if PHP gives you an error if you ask it to run this:

<?php
use abc\xyz;

That's a simple use statement creating an alias for a non-existent class, but it should do nothing at all if you try to run it. If you run it on an old version of PHP, you should get the same error.

[DrWilliamHobbs]

There is nothing and No errors.

OK, so now add the original lines back in, one at a time, until the problem starts happening.

My guess...

Switch the order of the "require" and "use" lines.
In your code you are using a namespace which is not available yet (since the loading of the files will happen AFTER the declaration.
I expect if you load the files before the "use", it should work (if the files are loaded properly)

require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

[Synchro]

No, that won't help. Use statements are just local aliases, the require statements have no effect on them. They only come into play when you instantiate a class.

theres is no change

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

same...

Two questions:

1. Are you using <?php at the start of your PHP file, incase unsafe / shorthand tags (<?) are not allowed
2. In case you are not providing the full code file, are you sure you are not using "use" inside a class declaration? Like:

class Foo { 
use PHPMailer\PHPMailer\PHPMailer;
}

it should be

use PHPMailer\PHPMailer\PHPMailer;
class Foo {
...
}

Maybe its good to provide you full file, since it seems to be a overall syntax error

Two questions:

1. Are you using `<?php` at the start of your PHP file, incase unsafe / shorthand tags (`<?`) are not allowed

2. In case you are not providing the full code file, are you sure you are **not** using "`use`" inside a class declaration? Like:

class Foo { 
use PHPMailer\PHPMailer\PHPMailer;
}

it should be

use PHPMailer\PHPMailer\PHPMailer;
class Foo {
...
}

I'll check it on tuesday, because my files are in the office ^^

So, what's the verdict?

Hello,
I have the same problem: PHP Parse error: syntax error, unexpected token "use"
The code I try to use is:

<? function cleaninput($input) { $input = trim($input); $input = stripslashes($input); $input = htmlspecialchars($input); return $input;} if (isset($_POST['name']) && isset($_POST['email'])) { if (isset($_POST['name'])) { $felado = cleaninput( $_POST['name'] ); } else { $felado = ''; }; if (isset($_POST['email'])) { $faemail = cleaninput( $_POST['email'] ); } else { $faemail = ''; }; if (isset($_POST['subject'])) { $targy = cleaninput( $_POST['subject'] ); } else { $targy = ''; }; if (isset($_POST['message'])) { $uzenet = cleaninput( $_POST['message'] ); } else { $uzenet = ''; }; require 'inc/Exception.php'; require 'inc/PHPMailer.php'; use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception; $mail = new PHPMailer(true); try { $mail->setLanguage('hu', 'inc/language/'); $mail->setFrom('[email protected]', $felado); $mail->addAddress('[email protected]', 'Someone'); $mail->addReplyTo($faemail, $felado); $mail->isHTML(true); $mail->Subject = 'Üzenet a weboldalról'; $mail->Body = 'Tárgy: <strong>' . $targy . '</strong><br/>Üzenet:<br/>' . $uzenet; $mail->AltBody = $uzenet; $mail->send(); $vissza = '<div id="form-message-success" class="mb-4">Üzenetét továbbítottuk.</div>'; } catch (Exception $e) { $vissza = "<div id='form-message-warning' class='mb-4'>Az üzenet küldése sikertelen. Hibaüzenet: {$mail->ErrorInfo}</div>"; }; }; header("Location: https://somedomain.hu/"); exit;

And what happens when you put the "use" and "require" lines on the top of your file, so as the first lines?

<?php
require ...
use...

It seems this works.
Thank you!

You're welcome!
That was what I was saying all along!
"Use" is handled compile-time, not run-time.
I guess TS has the same problem
