At my server , the host provide some alternative PHP.ini configs .
The only one that has the Extension Zip (which I need) is described as :
zip_cgi.fix_pathinfo
Advanced settings for experienced users with: cgi.fix_pathinfo = 1 and
Extension Zip Enabled
I am using the website primarily for wordpress , but I would like to know what are the possible effects (or meaning) of this .
from : http://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo
Provides real PATH_INFO/ PATH_TRANSLATED support for CGI. PHP’s
previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and
to not grok what PATH_INFO is. For more information on PATH_INFO, see
the CGI specs. Setting this to 1 will cause PHP CGI to fix its paths
to conform to the spec. A setting of zero causes PHP to behave as
before. It is turned on by default. You should fix your scripts to use
SCRIPT_FILENAME rather than PATH_TRANSLATED.
searching for google provided only blurry results for me ,as well as directly asking the host (the call center girls do not really understand , and the tech guys are not responsive ..)
It seems that the ZIP extension expects the URL to be passed along as a PATH_INFO variable. CGI and FastCGI implementations of PHP do not have PATH_INFO available, so when trying to pass the URI along, PHP fails. One way around that is to set cgi.fix_pathinfo to true.
