Summary0026063: Glue after String Array is being Deprecated

The Join() function will soon be strict on the order of its parameters (PHP 7.4), so any mismatches there will need to be changed. So far, I've only found an instance of the wrong Join() order: on line 653 of "core/layout_api.php"; but there may be others.

TagsNo tags attached.

Thanks @RealityRipple for entering the issue.

The Join() function will soon be strict on the order of its parameters (PHP 7.4)

The same applies to implode() as join() is just an alias for implode()

so any mismatches there will need to be changed

Not sure if it's needed or just good to have for the moment.
@RealityRipple did you try if it doesn't work?

According the PHP Wiki it should work, but emit a deprecation warning
So PHP 8.0 should be the first version where it must be changed.

For historical reasons, the implode() function supports passing the $glue and $pieces parameters in reverse order from the documented order of arguments. This is inconsistent and makes the argument handling non-standard (for example, strict types are not respected). This also affects the alias join().

Proposal: Emit a deprecation warning when calling implode($pieces, $glue) or join($pieces, $glue). Calling the function with just an array continues to be allowed: implode($pieces) does not generate a deprecation warning. 

So far, I've only found an instance of the wrong Join()

I had a very short look, but there are some more.
There are also some wrong calls of implode()

At present, I can't get Mantis to run correctly on 7.4b1 - I get repeated Internal Server Errors on bug and admin pages. However, I believe you're correct in that this issue only triggers a warning in 7.4. That's why this is under code cleanup and not an actual error.

Edit: Sorry, I said alpha, but it's beta. Unimportant, but just in case anyone else tries to run Mantis on b1, it'd be best to have some confirmation that there's some teething issues.

At present, I can't get Mantis to run correctly on 7.4a1

IMO not worth to invest time in going on to try it, as there is 7.4.0beta4 available

I'm aware and waiting for my webserver's host to update their 7.4 version. That's why I haven't gone through and tried to find all the causes of the ISEs and report them as bugs. As far as I know, though, this particular issue does not contribute to the failures I run into. Just a warning in the ol' error log.
