#16811 — htmlentities($dirs2[$i] not working

Hi 

A customers internet provider updated to the latest PHP version a week ago which caused quite some problems

one is tha htmlentities($dirs2[$i] does not longer work - it simply returns an empty string in case it contains ä ö or ü

Any idea why?

Because that is what the docs have specified for it to do when it encounters
illegal code unit sequences ?

As a first try I plugged "PHP 7 htmlentities"* into google, and the very
first result looked promising:
http://php.net/manual/en/function.htmlentities.php

*I used the generic PHP 7 ,  as you forgot to mention which sub version of
it exactly you're using/having problems with,  nor which version your client
upgraded from, which could be important too.

A bit down that page I found ENT_SUBSTITUTE, which mentions:

[quote]
Replace invalid code unit sequences .... with a Unicode Replacement
Character  INSTEAD OF RETURNING AN EMPTY STRING.
[/quote]

Also, this is, as the document shows, the behaviour as far back as PHP 4.

And by the way, I know very little about PHP, let alone about specific
versions.   My google-fu seems to be in working order though. :-)

Regards,
Rudy Wieser

Yes, indeed.  The OP most likely faces the problem outlined in
<http://php.net/manual/en/migration54.incompatible.php#115441>.  The
solution is simple: just explicitly set the $encoding parameter to the
desired enconding, or as of PHP 5.6.0, to set the ini directive
default_charset to the desired value.
