PHP 7

[Peper 10]

Many many updates required for PHP7.2

So far so good - testing everything and eliminating bugs

I had not seen that error before, but a little Googling and reading showed that it's popping up for others with other software.  Normally, PHP errors can be found with Google and see how others solve it.  My thought was that it was a string that needed to be cast, but i wasn't certain.  Most of the OSC code cast variables years ago, but addons don't have it.  Anyway, we both learned today and that's always a good thing.

Try this.  Did a little searching on StackOverflow and learned a little more.  Had to add the Hash class so I could experiment.  This yeilds an output now.

  function tep_random_name()
  {
    $letters = 'abcdefghijklmnopqrstuvwxyz';
    $dirname = '.';
    $length = floor(Hash::getRandomInt(16, 20));
    for ($i = 1; $i <= $length; $i++) {
      $q = floor(Hash::getRandomInt(1, 26));
      $dirname .= $letters[(int)$q];
    }
    return $dirname;
  }

It only works when there's no z in the output.  I ran into this on another piece of Harald's code I was playing with.  I found a workaround, but it's not a good one and I'm not sure why it even works.  Putting a -1 after $q stops errors.

  function tep_random_name()
  {
    $letters = 'abcdefghijklmnopqrstuvwxyz';
    $dirname = '.';
    $length = floor(Hash::getRandomInt(16, 20));
    for ($i = 1; $i <= $length; $i++) {
      $q = floor(Hash::getRandomInt(1, 26));
      $dirname .= $letters[(int)$q-1];
    }
    return $dirname;
  }

Why not use the PHP builtin has functions?

 

[♥John W 117]

I was just talking about the hash functions used, but I don't really have an argument for it.  http://www.php.net/Hash

I just put the function into a test page and the errors went away after the (int) addition, but I was just testing the output of the function.  I did get the string offset errors at first.

There are various functions around (e.g., tempnam, or possibly tmpfile) for creating unique temporary file names. It might be cleaner to use one of them. Also, when generating names, you have two problems:

1. I don't see anything to prevent duplicates (unlikely, but still possible).
2. Depending on who can see these names, some might be offensive. An easy way out of this to to drop the vowels and use only the 20 consonants.

Hi,

I had the same problem with my site after upgrading the server to php 7.  After upgraded from php7 all is good.

Have a nice day!

(At the risk of reviving an old thread, with a (perhaps) off-topic question ... )

Is there a problem with coding a shop to run under PHP 7.2, and actually running in under PHP 5.6?

The reason I ask is that I have several shop on my host's server. As I update each shop, I want to bring each up to be PHP 7.2 ready (even though my host currently only offers up to PHP 7.0), but leave all the shops at PHP 5.6 until all are upgraded. Will and PHP 7.2 specific code cause a problem under PHP 5.6?

TIA

@ArtcoInc generally speaking, it shouldn't be a problem. There is syntax on 7-7.2 that isn't supported on 5.6 but you're probably not going to be using any of it in your new version... spaceships <=>, null coalescing ($action = $_GET['action'] ?? 'default'), anonymous classes, constant arrays and a bunch of other things that don't spring straight to mind.

The only bit of code I can think of that doesn't work across versions is something to do with error-handling on evals but you probably haven't got any of that anyway. The evaluation order in statements is the other way round (eg. when working out what $$class->$method($param[$$key]) means but that should have been fixed by putting in curly braces to make it expllicit in the statement.

The approach would be - get a set of code running without issue on 7 and then turn the version back down to 5.6 for a test.

Just updated my server to run PHP 7.3. Running live site now using it

No significant issues at all - just a Deprecated warning in PHPmailer which was easily fixed.

Various benchmarks suggest about a 10% speed improvement.

PP should give warnings around php 7+.
No release covered that.

I am using v2.3.4.

I guess I could replace the "boxes" with div based code but it would not change the hierarchy of the classes that caused the error.
