PHP Deprecated Function – How to Solve Deprecated: __autoload() Issue

magento-1.9PHP

Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in C:\wamp64\www\magepro\app\code\core\Mage\Core\functions.php on line

My php version : 7.1.29

Can you please try to change __autoload function to spl_autoload_register after clear cache and remove var directory

/app/code/core/Mage/Core/functions.php on line 60

Let me know issue resolved with it or not ?

I think I fixed the issue by updating Magento to 1.8.0.1 and editing

app/code/core/Mage/Catalog/Block/Navigation.php line 254

from

$childrenCount = $children->count();

$childrenCount = count($children);

I can access the main page without any error message now!

each() function is deprecated in php 7.2 so change this function to foreach()

Change

while (list($name, $value) = each($options)) {
    $this->setOption($name, $value);
}

foreach ($options as $name => $value) {
    $this->setOption($name, $value);
}
