PHP changes X and Y axis of mysql database results - php

Question

I'm looking for a little help with the best way to get results to display the way I want from as few as possible database queries.
I would like to use one of my queries results columns as new unique columns for another table and merge like data.
For example
I run this query..
SELECT pd.production_date,pd.production_time,pd.production_net,
p.part_number, w.worker_name
FROM production as pd
INNER JOIN parts as p
ON pd.product_id = p.part_id
INNER JOIN locations as l
ON pd.location_id = l.location_id
INNER JOIN workers as w
ON pd.worker_id = w.worker_id
WHERE pd.production_date BETWEEN '$from' AND '$to'
AND p.part_number='$part_number'
ORDER BY pd.production_date
And I will get results like this:
production_date--production_time--production_net--worker_name
2013-01-10--390--96--MMahe
2013-01-10--400--101--RMaloney
2013-01-11--460--96--JBurris
2013-01-11--210--43--MMahe
2013-01-14--285--48--LTaylor
2013-01-16--60--8--MRocquemore
2013-01-16--460--90--TUsher
2013-01-17--450--85--MRocquemore
2013-01-17--460--84--TUsher
2013-01-18--450--73--MRocquemore
2013-01-18--460--93--TUsher
2013-01-18--240--24--JBurris
I then would like to display these results on a webpage like this:
Operators|01-10-2013|01-11-2013|01-14-2013|01-16-2013|01-17-2013|01-18-2013
MMahe|96|43|x|x|x|x
RMaloney|101|x|x|x|x|x
JBurris|x|96|x|x|x|24
LTaylor|x|x|48|x|x|x
MRocquemore|x|x|x|8|85|73
TUsher|x|x|x|90|84|93
My thought was first I need to filter my days to unique values then spit them out as the columns, which I have accomplished with this
$query=mysql_query($sql);
$days = array();
$results.='<div><table border="0"><th>Operator</th>';
while($row=mysql_fetch_array($query)) {
array_push($days,$row['production_date']);
}
$days=array_unique($days);
$column_count=count($days);
$n=0;
//create the columns (days) by looping through unique days
foreach($days as $value) {
$results.='<th>'.$value.'</th>';
}//end foreach
But now I don't see a way forward of listing values in the appropriate cells.
Do you have experience with doing this sort of data manipulation or can point me to a good example?
