I will fix it (in german manual).
English version doesn't need to be changed.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

The german descriptions of this similar functions again 
could be more precise.

Here is my suggestion:
strchr - alias von strstr
stripos - Sucht erstes Vorkommen eines Strings, liefert 
Position, unabh?ngig von Gro?- und Kleinschreibung
stristr - wie strstr, aber unabh?ngig von Gro?- und 
Kleinschreibung
strpbrk - Sucht erstes Vorkommen eines Zeichens von 
mehreren, liefert Reststring
strpos - Sucht erstes Vorkommen eines Strings, liefert 
Position
strrchr - Sucht letztes Vorkommen eines Zeichens, liefert 
Reststring
strripos - Sucht letztes Vorkommen eines Strings, liefert 
Position, unabh?ngig von Gro?- und Kleinschreibung
strrpos - Sucht letztes Vorkommen eines Strings, liefert 
Position
strstr - Sucht erstes Vorkommen eines Strings, liefert 
Reststring

With kind regards,

All German descriptions were already in sync with the English descriptions. IMHO adding additional descriptions make only sense if also the English descriptions would be changed.

I've reworded the description of stristr() with a more common term.

You are right: when the english descriptions would be changed it would 
be better.

I think its good, when the description tells what the function returns.
Then its not necessary to click one page deeper to the long description.

Warum auf eine gute kurze Beschreibung verzichten? ;-)

The German translation is only a translation, not a new written manual version. So yes, some function's return is simple to explain but also there are lots of functions with more complicated return values.

We try to keep the manual as consistently as possible. Because of that all functions have the standard result type in its signature on the head of their pages and also they have a documentation section with explained return types. 

So the question why not to write the complete result options in the function summary is easily answered: It is not possible to do that in all cases but in most cases the return value is implicitely described in the short description. (e.g. strpos - Find position of first occurrence of a string, that means an integer value of the first occurrence of the search string is returned by default.)

I am not asking for all options.
I am asking for a consistent short description text
that is no longer than the text now but more precise.

Maybe you are not familiar with german.

These functions are used often. So it would be nice when the short text 
gives the return value of the function.

Let me explain it:
strstr ? Find first occurrence of a string
First occurrence means the position. But in fact it delivers the part of 
the string haystack from the occurrence up to the end.

R?diger, both sammywg and I are native German speakers.

The manual needs to find a comprise between a short and a precise description. In addition, the translations need to stay in sync with the English manual.

If you want to propose changes to the short descriptions, please open bug reports for the English manual. Changes made there will be synced to all translations, including the German one, i.e. all versions of the manual could benefit from your suggestions then.
