While we update wordpress version 6.4 getting php error

[ravimakwana68]

Hello, today we tried to update WordPress version 6.4 in PHP 7.4.33 version and got PHP error. The current WordPress version is not stable.

error details is: PHP Fatal error: Uncaught Error: Call to undefined function str_contains() in /public_html/wp-includes/load.php

Hi there, welcome to WordPress Trac! Thanks for the report.

This was previously brought up in #59113, but could not be reproduced yet. WordPress has a polyfill for str_contains() in wp-includes/compat.php, and it should be loaded during the initialization process.

1. Could you provide the steps to reproduce the issue on a clean install?
2. Could you confirm that your wp-settings.php file has compat.php on line 34​?

Hey @ravimakwana68, I couldn't replicate it as well. Not sure, but will adding a check like "wp_installing()" in the compat.php for the polyfill help in any case @SergeyBiryukov?

Cannot reproduce either. Seems this is an one-off error that may have been caused by a failed or partial update. There doesn't seem to be a possibility for the polyfill to be missing as compat.php (where the polifills are) is always required before everything else including load.php. See: https://core.trac.wordpress.org/browser/trunk/src/wp-settings.php#L33.

Closing as invalid. Please feel free to reopen with more info on how to reliably reproduce this.
