I am currently getting data from a database using PHP and echoing the data out using:
$data[0]
This displays a full list of account numbers, I am wanting to put a href around this so that when I click on each one of the account numbers it runs another MYSQL query which breaks down to more information based on the account number that has been clicked.
How can this be done?
The href could point to another script which evaluates the $_GET parameters and builds a query from it, like in
12345
and
<?php // details.php
...
mysql_query( "select * from mydata where id=$_GET['id']" );
This is just a pointer, and the example is prone to SQL injection etc.

I would like to know how I can create a list of top donors, in which the user who donates the most is in the first position of the list.
In order to donate, you must be logged in
How can I do something like that using php and mysql?
This is only how much i understand your question.
First you need to create table for donors which the storage of their data, and 2nd is to make table for donate which holds the donator.
Then to sort the donator by donated the most, just use COUNT sql query to get the highest donate number.

In order to find websites with potential sql injections, it is possible to use google dorks like "inurl:.php?id="
From the results that google will give, does it mean all the websites listed use sql database (mysql, oracle or any other)?
As it is a backend call, we can't exactly say, that it related to a Database as well. The reason is that while captured based on $_GET['id'], the returning value can be decided only upon the backend, solely based on PHP. So SQL connection is not essentially needed in that purpose.

Basically you need to get the data, manipulate it and send it to the HTML page. Once you get the data in HTML you can present it any kind of look-n-feel as per your needs.
You can not expect exact answers for such questions - so I suggest you to be more specific with QUESTION and make sure that you also share the source code that you tried so far.

The problem is that I must catch situation when some variable (and I don't know it's name, that is I don't know where this value first arises) matches some record in database. The way I think it could be done is to run after each statement an external code against array of local and remote variables. In that external code would be a simple foreach loop and db query, the script would then output line number where given situation happened.
Is this possible with xdebug ?
There is a function for that, http://php.net/manual/en/function.register-tick-function.php more documentation on ticks is http://www.php.net/manual/en/control-structures.declare.php here.

return(array($clientName,$salesPer,$prospectVal,$projID));
The projectID is dynamically added in database for each entry, now how can i return the ID. As i have not set any variable in PHP to map the database field.
Can anyone guide me on this.
If you're asking how to get back the ProjectID after it has been inserted into the database and automatically assigned, I suggest using something like the following:
$projID = mysql_insert_id();
immediately after running the insert statement.
