Help with Array

[mpar612]

I have an array that is populated with two different types of information. One type is itemId => value and the other type is itemTemp => value. There many values in the array, but they alternate. The values alternate and are contained like so:

itemId=> value1
itemTemp => value2
itemId=> value1
itemTemp => value2
itemId=> value1
itemTemp => value2

How do I print these out in a way that can delineate between the different types of data?

For example, how can I print like this:

<tr>
   <td>
      itemId
   </td>
   <td>
      value1
   </td>
</tr>
<tr>
   <td>
      itemId
   </td>
   <td>
      value2
   </td>
</tr>

And repeat that table structure until all items in the array have been used.

Thanks in advance!

Are you not using itemTemp? If not and the itemId key will remain the same for all the values you would like to echo on screen. You could use this method.

$items = array(); //the array containing your items
foreach($items AS $k => $v){
	if($k == 'itemId'){
		echo '
		<tr>
			<td>'.$k.'</td>
			<td>'.$v[0].'</td>
		</tr>';
	}
}

Well, probably the better way would have been to build it as a 2-dimension array, e.g.:

$items = array();
$items[] = array('itemId' => 'value1', 'itemTemp' => 'value2');
$items[] = array('itemId' => 'value3', 'itemTemp' => 'value4');
// etc....

Then it would be a simple matter to use a foreach loop:

foreach($items as $arr)
{
   echo "<tr><td>".$arr['itemId']."</td><td>".$arr['itemTemp']."</tr>\n";
}

Thank you both for your responses. I have been working with both of your ideas. I have the following form. This pulls all items for a database and prints the following code for each item:

<tr>
<td height=\"21\" valign=\"top\"><b>
<input name = \"$itemId\" value=\"$value\" size=\"3\" /></td>
<td><font face=\"Times New Roman\" color=\"#990000\">$itemName </td>";

if($temperature == "Y") {
	echo "<td><select name=\"$itemId - temperature\">
		  <option value=\"NA\">-- Select --</option>
		  <option value=\"BR\">Blood-Rare</option>
		  <option value=\"MR\">Medium-Rare</option>
		  <option value=\"M\">Medium</option>
		  <option value=\"MW\">Medium-Well</option>
		  <option value=\"WD\">Well Done</option>
		</select></td>";
} else {
	echo "<td>N/A<input type=\"hidden\" name=\"$itemId - temperature\" value=\"N/A\" /></td>";
}

echo "<td><b>$$total</b></td>
	</tr>";

$arr[] = $total;
}

Originally, I used the following code to populate an array and session variable so the values can be used on a different page:

if(!empty($_POST)) {
	foreach($_POST as $key => $value) {
		if($key != "_submit_check" && $key != "button"  && $key != "0" && $key != "") {
		      if(!empty($value)){
			  $arr[$key] = $value;
			}
		}
	}	
}

$_SESSION['order'] = $arr;

Is it possible to create a 2 dimensional array as you described, Nog Dog? I tried adding something like $arr2[$key] = $value, but it didn't work.

Any thoughts would be greatly appreciated. I am new to using arrays in this way.

Thanks!
