[PHP-DB] Creating a pdf document
Hello, I was wondering if I could save the result of a query in a pdf document. I looked for any functions that might help, but I got confused because I could not see how/where exactly to insert the necessary .dll's. I'd like to do this (saving the output of a query) by using mysql installed on a Irix machine, and PHP4. If this is not possible, could I create a pdf document or a word document from a query from either Access database or mysql on a win2k system, PHP4.1? Any references that might help?

Yes.

[PHP-DB] displaying images
Hello, I'm storing image URLs in a varchar text field for items in my database. The problem is not all the items in the database have images, so when i do a query that displays multiple results some have images and some have the nasty red Xs. Is there a way do some kind of IF statement. If the image url is there, display image if not display No picture available or something like that?

Zach, We're going back and forth on this and getting no where...

Do you mean last entered, or do you mean the row with the field containing the highest value in the column - for example. Some people are used to the idea that there is also some 'phantom' rowId that counts/labels each row. In other file systems this might have been the case, but the physically last record in an RDBMS table-file may not conform to either of the "last" definitions mentioned above.

Re: [PHP-DB] # of Records in Table
The last record should be whatever the last record is in the table. For example, if there are 1000 records in the table which COUNT(*) will tell me, how can I get the password for record 1000. The only thing I can do that would probably work is two query statements, one selecting COUNT(*) and the other selecting "password". What I don't like about this method is that I would have to retrieve all of the passwords into an array, which I would assume would be slow on larger tables. Ideally, I thought their would be a way to do this operation in one select statement. Any thoughts?

It does not. However, I could easily add this in if you have a suggestion that would work. Ideally, I thought their would be a way to do this operation in one select statement. Any thoughts?

[PHP-DB] defines and mysql
i've just found that php 4.1.1 on my linux box is having issues with defines
and mysql:
i have two defines,
define("DB", mysql_connect($host,$user,$pass));
define("DB2", mysql_connect($host2,$user2,$pass2));
what i'm finding is that when i open the second connection with a define my
page takes forever to load. it was not like this in previous versions of
php. when i use variables for DB and DB2 it works fine.
is this in php on purpose? or is this a bug? has anyone else encountered
problems like this?
d.

Re: [PHP-DB] Resource Id #2
Good, I'm glad it worked!!!
I see a lot of people using mysql_fetch_array().
Which is fine...But I'm more into Object Oriented programming...and
that's why I always use mysql_fetch_object()
Good luck!!!
