Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

n	unsigned short (always 16 bit, big endian byte order)

OMG, i saw your message and I was angry ! but i check and in French it is written "entier court sign?"
so it means "signed short"
It means that there is a doc error.

We usually state translation bugs as bogus but I hope French translation team close this soon.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
