Error after upgrading to php 7.3: "Deprecated: Function create_function() "

[verticality]

Hello coders!
After upgrading my version of php from 7.1 to 7.3 my forum started to display this lines of code at the header of the forum, destroying all the design.
¿Does someone can give me a hand to find how to fix it?

What version of SMF are you on? Those errors should be suppressed if you are on latest SMF 2.0.x

[Sir Osis of Liver]

<sigh>  Officially, 2.0.17 supports php 7.2/7.3, but it contains deprecated code and will log a lot of errors.  There's a mod that fixes 7.2, haven't tried it, don't know if it works for 7.3 -

Yes it works fine for PHP 7.3.

[Sir Osis of Liver]

Thanks, Chen.  If I ever get around to updating my prod forums (still running 2.0.15 in php 7.1) I'll give it a try.

[Arantor]

Oh god we're not still arguing over the definition of 'supports', are we?

For the record, I agree with the team that 'supports' is fine here since the errors are warnings that 'you're using a thing that will go away in the future'. If your definition of 'supports' was as narrow as it is here, you should never have upgraded to SMF 1.1 or used PHP 5 ever since there are suppressions of errors of a similar vein for PHP 5 strict standards that couldn't be changed without breaking PHP 4 support which was necessary for a very long time.

Also, when this is removed in PHP 8, it becomes a pretty short replacement function that just works. It's only now while it's noisy that it's a problem.

Hi guys.
Still my problem hasn't been solved.
I'm running SMF 2.0.17  with PHP 7.1


I can't understand the origin of the problem in order to fix it.

[vbgamer45]

We can do a workaround and hide the errors if you wish by changing the error reporting setting i believe in index.php might be one other file though as well.

[SpacePhoenix]

If you've got xdebug installed, the "scream flag" might be turned on which causes the error suppression operator (the @ operator), to be ignored.

The "scream extension" can also have the same affect

[Sir Osis of Liver]

Shouldn't be seeing those errors in 7.1.

[shawnb61]

2.0.17 suppresses the errors.  Thru php 7.3, they should not even be logged.  There is something going on in some of these environments where the error suppression is - well, suppressed...

I think SpacePhoenix is on to something...

[Sir Osis of Liver]

This is the downside of using deprecated code in a current release.  Some hosts are up to php 7.4, with no option to downgrade.

[verticality]

I can change to whatever version of PHP I'd like, including 7.4.
But changing the version doesn't fix the error.

Feels like the last upgrade mess someting permanently.

[Chen Zhen]

Did you try the suggested SMF utility?

[verticality]

After trying everything mentioned above I solved the problem.

I used the fix mentioned above but it has errors and couldn't be implemented.

So what I did was to reinstall the forum following this guide
https://wiki.simplemachines.org/smf/How_to_upload_a_fresh_set_of_files

Then, and only then I could apply the fix properly.
Note: before the fix the problem persisted.

After that I reinstalled the mods and themes. Now everything runs smooth.

Thanks for the help guys!
I hope this experience can help someone else.

[Chen Zhen]

The utility performs many edits to SMF source files mostly concerning BBCode.
If you previously manually edited the particular code it looks for or if an outdated mod edited the particular code it looks for, it will show parsing errors.
Most up do date mods will use hooks to add things such as BBCode so it should rarely be an issue.

I'm glad you were able to figure it out and that your forum is now working without logging PHP deprecated errors.
