Retrieve Data From Database And Count The Number Of Times The Data Occurs?

I have a couple of tables in MySQL that I'm working with that do not have any relation. They do have a column of similar data (Postal Codes / Zip Codes). What I have to do with these tables is compare the postal codes from one table compare them to the postal codes from the first table and count them.

For Example. Table A has a postal code of T0A and T0B (I use only the first three characters in the postal code as this is all I need to compare against) Table B has 13 rows where the postal code matches T0A and 3 rows where the postal code matches T0B.

So the outcome would look like:

T0A = 13
T0B = 3

HOWEVER, then I need to take these and separate them by city, so since both T0A and T0B could be one city I would need to take those and add them together and get something like.

Edmonton = 16

I've been doing this with for loops and arrays. So I'm reading the data from table A into one array and the data from table b into another array. Then I compare the postal codes from table B to the postal codes in table A using nested for loops in order to count the number of occurrences of the postal codes and then I store them in another array. This is all fine and dandy however separate the counts into their correct cities and I'm sitting here thinking there must be an easier way to do this.

Structure - Table A

jos_postalzip_redirect | CREATE TABLE `jos_postalzip_redirect` (
`id` int(11) NOT NULL auto_increment,
`country_code` varchar(2) NOT NULL,
`prov_state_code` varchar(2) NOT NULL,
`city` varchar(60) NOT NULL,
`postal_zip` varchar(6) NOT NULL,
`email_address` varchar(60) default NULL,

Nested While Loop - Retrieve A List Of Data From A Database

I want to retrieve a list of data from a database. The MySQL query involves an inner join on a one-to-many relationship between two tables. The query involves authorities, and authcourses (courses that are run by the authorities). So, a table of results might look like this:

course 1, description, date, authority 1
course 2, description, date, authority 1
course 3, description, date, authority 1
course 4, description, date, authority 2
course 5, description, date, authority 3
course 6, description, date, authority 3
...
etc. etc.

I want to display the results more like this:

[Code]....

I'm stumbling around blind here at the moment. I guess I want each authority to be an array $authorities[], which contains the relevant course data. Er... yeah that's as far as I've gotten. I'll need all this to work with a while loop, so that my html can be generated dynamically. Every kind of code or pseudo-code I try and write just makes my brain dribble out of my nose a little.

Call Function That Is In A Different File From A Javascript Function To Retrieve Data From Database?

How do you call a PHP function that is in a different file from a JavaScript function?I have a JavaScript function that recieves a variable from an onClick function. The variable is an id that I will use to retrieve data from MySQL database. The variable is then passed on to a PHP function that will access the database to get the data and return back to my JS function for display, but it does not seem to be working. How can I get it to work? I am using CodeIgniter PHP.

Here is my code:

JavaScript in a different file called divUpdate.php

<script type="text/javascript"
src="http:[url]....
<script type="text/javascript">[code]....

Then, in the controller home.php I have a function that the JavaScript uses to pass the id that will then be used by the model to retrieve the data from the database

function get_venue_description($venueID){
echo $this->venue_model->retrieveData($venueID);
}

For some reason the code in the JavaScript divUpdater.php doesn't work. It looks correct but doesn't work.
