I've just added a new service to e-gineer to help in the search for
domain names.  It checks domain availability, trademarks, definitions,
synonyms and similar words.  Check it out at:

Can I use Javascript to submit two forms simultaneously from the same
page?
How can I run two cgi scripts with a single form submission?

browsers only submit a form at a time, either by request of the user or
programmatically.  So you can't use Javascript to submit two forms
simultaneously.

What you may want to do is to submit a form to a page which code submit
the form data to those other two CGI addresses.  You may find here an
HTTP PHP class that you may use to POST as much forms as you like:

    http://phpclasses.UpperDesign.com/browse.html?package=3

You could just have the first CGI submit to the second CGI? That would
be a lot simpler. I don't even know if it's possible to submit to
multiple CGI's.  I don't think it is, but if the CGI's return a 204 No
Content status, it may be possible.

Can I check Unix system passwords from PHP?

Martin Koistinen

Do you really want PHP to authenticate your users based on their system
passwords?  This is probably not a good idea.

Have you considered a simple database of web users or at least Apache's
AUTH DB?

By authenticating your users with their system passwords, you are 
asking them to send their passwords in cleartext over the internet 
each time they log in.  You are also creating more accounts which 
ultimately increases the likelyhood of a break-in.

What is ldconfig used for?

ldconfig is used to generate a hints file that is used by ld.so to
locate and link to shared object libraries at run-time.  When you
compile a program and link it with shared object libraries, the
libraries are not included in the executable program,  just references
to the global data and functions as well as the name of the shared
object file that contains them.  When you run the program, the ld.so
file that is in your executable has a list of shared object libraries
that it was linked with.  ld.so is responsible for finishing the
link operation by resolving these references at run-time to the
shared object libraries.  If the shared object libraries are not
already loaded into memory, they are loaded now.  If they are already
in memory, they don't need loading.  ld.so then resolves variable
and function references by updating the Global Offset Table for
global variables and the Procedure Linkage Table for functions.
It gets the information for updating these tables from the shared
object libraries.  It finds the shared object libraries by looking
in the hints file.  The hints file is built by ldconfig.

What happens if the user leaves a form field which is part of an array
empty?

Manuel Lemos

If the field is empty, an entry with an empty string will be added to
the array.
