I"ve stumbled upon this issue today when upgrading a phpBB-based trang web from PHP5 to lớn PHP7. I came up with three different workarounds that can be used for different scenarios, the second one being the only viable one for mine since I had template-based regexp stored within the filesystem/db instead of static ones, which I couldn"t easily alter.

Basically, I went from this:

$input = preg_replace($search, $replace, $input);to something like this:

$input = preg_replace($search, function($m) use ($replace) { $rep = $replace; for ($i = 1; $iNeedless khổng lồ say, this is nothing more than a quick-and-dirty workaround, only "viable" for those who cannot easily refactor their code with the updated preg_replace_callback function without having lớn use any potentially unsecure eval() call: for this very reason it should only be used if the developer has full control over the replacement strings/rules và is able to lớn properly test/debug them. That said, in my specific scenario, I was able to lớn effectively use that in order khổng lồ get the job done.

IMPORTANT: the str_replace and/or the eval() could break some replacement rules unless they are "properly" defined taking the above code into account.

For further info regarding this issue và other alternative workarounds you can also read this post on my blog.
