Does PHP 7 causing issues with older WordPress website?

Hi developers out there,

I need to know that, Does php 7 cauing any problems with WordPress websites? If so, then share what are the major issues you have found when you migrating your old WP website with new PHP 7.

Are those issues really makes you trouble or Is there some more issues that's been list out here.

Share your thoughts, waiting to hear from you all.

As with any new version of PHP (or with anything for that matter), the possibility
of problems arising is very possible, especially since with each release comes a few
depreciated functions. The best thing to do would be to install a copy of your blog
on a server with AND without php7 to see if it causes problems for you, your WP
install and the plugins you have implemented.

In my experience, when newer versions of PHP are released and implemented, any
problems that arise are s usually from the plugins more so than WP itself.

That said, if YOU are having problems with your copy of WP, it's also best to check
out all of your plugins as the problem will most likely stem from a plugin rather than
WP itself. Troubleshoot by deactivating ALL your plugins and then activating them
one at a time. If no problems arise, you're good to go. As soon as a problem arises,
you'll know exactly what it causing it.
