Any reason why in_array is returning TRUE when one has a 0 value on
the array ?
That's weird, 5.2.6 does the same thing. There's actually a comment
about this on the in_array manual page from james dot ellis at gmail
dot com...
Be aware of oddities when dealing with 0 (zero) values in an array...
This script:
It seems in non strict mode, the 0 value in the array is evaluating
to
boolean FALSE and in_array returns TRUE. Use strict mode to work
around this peculiarity.
This only seems to occur when there is an integer 0 in the array. A
string '0' will return FALSE for the first test above (at least in
5.2.6).
So use strict mode and this problem will go away. Oh, and please read
the manual before asking a question in future.

What about using the === and !== comparisons to compare and make sure
that 0 is not giving a false false.
That's effectively what using strict mode does. RTFM please.

[PHP] Displaying information from table graphically
I have a PHP application that accesses data from MySQL. There is table called "rooms", and table called "beds". There is another table called "patients". Patients are being placed into beds, and beds are in the rooms. PHP application currently displays all information in textual mode via regular HTML tags. But I would like to have that information displayed in graphical mode instead of textual mode. Is there a way to display this information from the database graphically. Graphic would represent a room, and it would contain beds inside. You would be able to see visually which beds are occupied and which are free by looking at the graphics. User of the system wants pictures instead of text displayed via HTML tables as a list of entries. Anyone knows anything like this?

RE: [PHP] Model Web Site
hi... for what it's worth. the best approach might be to find a few sites that have the functionality/layout you like. there are probably a few of them that you'll run across that meet what you have in mind. use these as your basic guides. add additional features that you'd like. you now have (roughly speaking) the requirements/functions that you want your final site to have. from here, you can figure out which "scripts" you want to apply, and what you're still going to have to provide. keep in mind that you can't simply throw scripts together, but you can use them to get a sense of the underlying logic. you can also use them to see how to develop your look/feel of your site. looking at various scripts also gives you a chance to think about how you want to implement your security/setup, as well as the underlying database schema.. you can find plenty of apps/scripts on freshmeat.net/sourceforge.net as well. have fun! -Original Message- From: Stephen [mailto:[EMAIL PROTECTED] Sent: Thursday, November 20, 2008 2:17 PM To: PHP-General Subject: [PHP] Model Web Site My prime hobby is photography and the next is web site building.

User of the system wants pictures instead of text displayed via HTML tables as a list of entries. There's a couple of ways you can do this with differing qualities. 1) Use GD or ImageMagick to composite images together to represent the room. This would allow you to create the best looking images. You can either store images for rooms with 1, 2, 3, 4, ..., n beds and overlay markers to indicate occupied beds, or you could composite the whole thing. 2) Slice images up such that you can build a room using positioned divs. This would be a lot easier but you'd be limited in what type of textures and looks you can give the rooms. On the other hand this could turn out to be more flexible as you could arrange it to allow rooms of any dimensions with any number of beds. Personally I'd opt for 2 based on the KISS principle, but you could potentially run into browser compatibility issues depending on your target platforms. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks,

general idea:
in mysql you have marked beds with 0 not occupied and 1 occupied.
then you have two images: bed_occupied_0.gif and bed_occupied_1.gif and,
depending on record from mysql different image should be shown.
same with number of beds in room.
for example. there is 4 beds maximum per room.
you have 5
images no_of_beds_0.gif (actually, this is a transparent 1x1 gif)
images no_of_beds_1.gif
images no_of_beds_2.gif
images no_of_beds_3.gif
images no_of_beds_4.gif
$query = mysql_qurey("select no_of_beds from beds where room=123";
$result = mysql_fetch_assoc($query);
echo "border=0 />";
something like that.

IPv6 support was added in 2001. You didn't say what version of PHP you are having this problem with, so it's hard to say why yours doesn't have support for it. Perhaps it was configured with --disable-ipv6 for some reason, or compiled on a system without the necessary libraries installed (which would be somewhat surprising).
