vBulletin 4 & PHP 7 - drastic speed improvement!

@Alan_SP
My blog works fine from here, weird.
Here's the post with the upgrade instructions: http://pastie.org/pastes/10622659/te...xtqlc7ktv3mwxg

Thanks for the info, I just tested it with FireFox, it seems you're blocking my browser (Opera). Probably same as was with Ozzmodz.

Hello all,

first of all thank you for the blog post. We're about to migrate our web services to PHP 7 as well and vB forum is one of them. I've done the modification as mentioned unfortunately i am facing an issue when posting a new thread/post. It will end up in blank post.

New thread with some text


This is how it looks like after submit


Firebug confirms that no text at all in the body


I've tested it with all plugins disabled via "define('DISABLE_HOOKS', true);" and with the default template as well. Still facing the issue.

We're running following setup in our test environment:
vBulletin 4.2.2 Patch Level 5
PHP Version 7.0.8
Web server: fpm-fcgi

I've also found following warnings in error.log ... not sure if related or just another things to be fixed.

(Btw, two of the fixes in that blog are not actually correct).

• includes/class_hook.php (to fix constructor error)
• vb/exception/parser.php (to fix redefinition of argument error)

Also I had to change the datastore class in config.php back to vB_Datastore_Filecache since there's no PHP 7 version for APC/XCache or Memcached. You don't need it anymore anyway since OPCache has been introduced and it's extremely fast.

Another thing to keep in mind is that PHP 7 deprecates the mysql_* functions. In case you have any plugins or custom scripts installed which makes use of that then it will not work.

You should send these to vB team so we can use PHP7 on forums earilier

I want to upgrade to PHP7 for my hosting but I could not because my vB forum is not compatible with PHP7 so I have to leave it.

I'll probably write a follow up blog for more changes/fixes for PHP 7.
Although you state that some of the fixes are not "correct", my forum has been running just fine for about 8 months now on PHP 7.

Did you even bother to read the link I posted ?

Actually, I said two, not some

One you would never notice unless you somehow triggered exceptions, even then it would probably just display wrong information.
The other would, I think, break something (custom tags ?) I'm not actually anywhere I can look at code atm.

If they were the only changes you made, you are hiding a ton load of warnings.

The PHP 7 test version has been available for anyone who requests it for almost two months now, posted here, vb.com, and even TAZ - only three people have shown any interest. The Alpha's next month will basically be that code.

I love vB 4.2.5 Beta 1 and together with PHP7 it runs perfectly.

Are you running it with PHP7.1 or PHP 7.0.*?
PHP 7.1 should speed it up by a tiny bit more.

I have the beta as well and would love to upgrade but I think I would have to go through older plug ins and I know my Photopost gallery would have issues as well.

I may do it though at some point.
