PHP 7.1 Warning: A non-numeric value encountered in \wordpress\wp-includes\SimplePie\Parse\Date.php on line 694

[aquakitty]

When using the function get_permalink() for the RSS feed, I am getting this error.

I fixed it by casting match[] for now.

<?php
$second = round($match[6] + $match[7] / pow(10, strlen($match[7])));

Modified line:

<?php
$second = round((int)$match[6] + (int)$match[7] / pow(10, strlen($match[7])));

Hello @aquakitty, welcome to WordPress Trac!

Thanks for your report. SimplePie is a third-party library and core isn't using the latest one (see #36669). The warning has already been fixed in ​https://github.com/simplepie/simplepie/commit/1111dab1baced14aaf05509c41ee416c3fc6a961.

Duplicate of #36669.

Great, thank you I tried finding this but I guess I need some work on my search skills.

This problem is STILL there in Wordpress 5.1.1

I manually edited the line, but upon last automatic update the line reverted back to what it was.

Server: Ubuntu 18.04
PHP: 7.2
Nginx: 1.14.0

nginx server log is full of :
PHP message: PHP Warning: A non-numeric value encountered in /var/www/idyl.io/html/wp-includes/SimplePie/Parse/Date.php on line 694

As of 30.04.2020, this error is still happening.

[30-Apr-2020 04:13:09 UTC] PHP Warning: A non-numeric value encountered in /..../..../public_html/wp-includes/SimplePie/Parse/Date.php on line 694

I've added the fix from above comment:
$second = round((int)$match[6] + (int)$match[7] / pow(10, strlen($match[7])));

and commented out the original:
$second = round($match[6] + $match[7] / pow(10, strlen($match[7])));

Thanks.

This error is still happening there too. Upgrading from php7.0 to php7.3 produced the following warning :
