On PHP 8.1: TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in _filter_url()

Please review.

Thank you for the patch. I was having the same issue after a php 8.1 upgrade, but for me it was causing an error during cron runs. After applying this patch, cron ran without error.

Thanks for reporting and working on this.

This patch will fix the error itself, but it would not fix the root cause of the problem. I suppose that this is a duplicate of: 🐛 [D7] preg_split in _filter_url breaks for long html tags Needs work (the parent D10 issue is already fixed: 🐛 preg_split in _filter_url breaks for long html tags Fixed ). However, until that issue is fixed, you can use the patch from this issue as a quick-fix, if you experience the problem, but I doubt that it will be committed to D7 core in this shape. We should rather focus on fixing the real issue here: 🐛 [D7] preg_split in _filter_url breaks for long html tags Needs work .

Arrived here searching for this error.

We experienced this error on admin/content
Drupal 7.97
PHP 8.0.30

Aplying the patch fixed the error.
