Help with processing an array

[awrigh4]

I have an array that looks like this - I've used vegetables for clarity 😉

Food Type------Food--------Eaten

Vegetable-------Carrots-------1
Vegetable-------Peas----------null
Vegetable-------Broccoli-------1
Fish-------------Cod----------null
Fish-------------Tuna---------1
Meat------------Steak--------1

I would like to process the array to arrive at the following output

There are 3 Vegetable types and you have eaten 2
There are 2 Fish types and you have eaten 1
There are 1 Meat types and you have eaten 1

I am totally stuck and have got nowhere for over a week now. Is there anyone who can help with the PHP code needed to process this array?

I would start with a multi-dimensional array like this:

<?php
// multi-dimensional array
$food = array(
			  // veggies
			  'vegetables'=>array('carrots','peas','broccoli'),
			  // fish
			  'fish'=>array('cod','tuna'),
			  // meat
			  'meat'=>array('steak')
			  );


// I like to eat steak!
echo 'I like to eat ' . $food['meat'][0] . '!';
?>

And go from there. If you have already tried this, then post your actual code...

Thanks Rodney

I have followed your suggestion (I think) and created a multidimentional array as follows

$region_list1_result = mysql_query($region_list1_sql);
while ($region_list_row = mysql_fetch_array($region_list1_result,MYSQL_NUM)) {
$tempvalues =array('article' => $region_list_row[2], 'read' => $region_list_row[3]);
$temparray = array('region' => $region_list_row[0], 'values' => $tempvalues);
$region_list_result = array_merge($region_list_result,$temparray);
}

$region_list2_result = mysql_query($region_list2_sql);
while ($region_list_row = mysql_fetch_array($region_list2_result,MYSQL_NUM)) {
$tempvalues =array('article' => $region_list_row[2], 'read' => $region_list_row[3]);
$temparray = array('region' => $region_list_row[0], 'values' => $tempvalues);
$region_list_result = array_merge($region_list_result,$temparray);

So now I have this array called $region_list_result that should be a list of regions and against each region is a list of articles each with a flag showing whether the article has been read or not.

I am still having trouble extracting and traversing this array (I guess that's why I was avoiding multidimentionals),

The output I would like is something like this.

For REGION1 you have 3 ARTICLES of which you have READ 3
For REGION2 you have 4 ARTICLES of which you have READ 1

From the following array (I'm not sure about the syntax for representing a multid array so hope this makes sense.)

[REGION1,[ARTICLE1,1]]
[REGION1,[ARTICLE2,NULL]]
[REGION1,[ARTICLE3,1]]
[REGION1,[ARTICLE4,1]]
[REGION2,[ARTICLE1,1]]
[REGION2,[ARTICLE2,NULL]]
[REGION2,[ARTICLE5,NULL]]
[REGION2,[ARTICLE6,NULL]]

Are you able to help futher ?

I believe someone here could help. However, it would be to your benefit if you posted all the relevent* parts of your code, and wrap it within [ PHP]... code here ...[ /PHP] bb-code tags (just below the color selection menu) to make it easier to read.
