In order to reproduce this issue use a table rate in your test environment then follow the checkout steps to the end. Starting with PHP 8.1 to 8.3 you will get this error in the OM log file. ``` Deprecated functionality: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/app/code/core/Mage/Shipping/Model/Resource/Carrier/Tablerate.php on line 131 ``` My approach is using strlen($variable ?? '') but it could be strlen((string) $variabile) too. I am open to opinions.

| while (strlen($postcode ?? '') > 1) { | |
| $postcode = (string)$request->getDestPostcode(); | |

It's more efficient as it's outside the loop.

good catch @addison74, I like @kiatng version, it looks neater to me because it doesn't get executed inside the loop
