Magento 2.4.4 with php 8.1 issue

Question

I have version 8.1.3 of PHP and I am getting the following error message on Magento 2.4.4:

    Exception #0 (Exception): Deprecated Functionality: strtotime(): Passing null to parameter #1 ($datetime) 
of type string is deprecated in /data/web/magento2/lib/internal/Magento/Framework/Stdlib/DateTime/Timezone.php on line 259

on the homepage, category pages etc. Have you faced this issue before ? Do you have any suggestions how to fix it ?

Thank you

Answer 1

I think you are missing both these things

• PHP fpm all extensions
• Composer version

You can also rename the vendor and update the composer.

Answer 2

Sorry i can't understand why this issue getting in core modules but i was facing same issue like PHP Deprecated: explode():. So i have found temporary solution for it.

Below is that us my issue solution.

$comp_uids = explode(',', $result['comp_uids'] ?? '');

And i am not sure about you issue but try below solution once time.

return strtotime($date) ?? '';
