How to fix a PHPMailer __autoload() error?

Question

I use phpMailer for the processing of mail sent from the website. This morning I suddenly got the following message:

Fatal error: __autoload() is no longer supported, use spl_autoload_register() instead in C:\xampp\htdocs\webapp\PHPMailerAutoload.php on line 45

I have PHP 8.0.0 running on the server

if (version_compare(PHP_VERSION, '5.1.2', '>=')) {
    //SPL autoloading was introduced in PHP 5.1.2
    if (version_compare(PHP_VERSION, '5.3.0', '>=')) {
        spl_autoload_register('PHPMailerAutoload', true, true);
    } else {
        spl_autoload_register('PHPMailerAutoload');
    }
} else {
    /**
     * Fall back to traditional autoload for old PHP versions
     * @param string $classname The name of the class to load
     */
    function __autoload($classname)
    {
        PHPMailerAutoload($classname);
    }
}

Did you check all your code would work with PHP8 before upgrading? — RiggsFolly, Dec 17 '20 at 18:29

This is An Edited AutoLoad File in: PHPMailer\PHPMailerAutoload.php

function PHPMailerAutoload($classname)
{
    //Can't use __DIR__ as it's only in PHP 5.3+
    $filename = dirname(__FILE__).DIRECTORY_SEPARATOR.'class.'.strtolower($classname).'.php';
    if (is_readable($filename)) {
        require $filename;
    }
}

if (version_compare(PHP_VERSION, '5.1.2', '>=')) {
    //SPL autoloading was introduced in PHP 5.1.2
    if (version_compare(PHP_VERSION, '5.3.0', '>=')) {
        spl_autoload_register('PHPMailerAutoload', true, true);
    } else {
        spl_autoload_register('PHPMailerAutoload');
    }
} else {
    /**
     * Fall back to traditional autoload for old PHP versions
     * @param string $classname The name of the class to load
     */
    spl_autoload_register($classname);
    
}

Changes are done here: spl_autoload_register($classname);

Thanks

You're using a very old version of PHPMailer – that code has not been in PHPMailer for 3 years. PHP 8.0 is officially supported as of PHPMailer 6.2.0, and make sure you read the upgrade guide.

Your issue will be resolved by changing function __autoload($classname) to function spl_autoload_register($classname) which has no adverse affect on the output.
