PHP: Implode Comma Separated in min() function

Question

I'm trying to implement the min() function in my PHP code. The min value should be retried like this:

$ar=array($data[Price]);
echo min($ar);

The problem is that when I echo out $data[Price] I get my prices without commas nor spaces, so it becomes something like this:

$ar=array($data[Price]);
echo min(373945);

But it should be:

echo min(37, 39, 45);

to get 37.

Is there any way to get comma separated values with implode?

My var_dump result of $data[Price]:

NULL 37.00NULL 39.00NULL 45.00

Can you add a `var_dump($data[Price])`, so we can see what the actual data you're working with is? — andrewsi, Aug 15 '13 at 17:06
Then first its `$data[Price]` which needs to be formatted accordingly, Rest of the things will resolve auto — Hanky Panky, Aug 15 '13 at 17:06
@user2635574 - you don't need the `array`, I think. Just pass `$data['Price']` into `min()` as it is. — andrewsi, Aug 15 '13 at 17:13

@user2635574 - put `var_dump($data['Price'])` on the line before you call `min()`. What is the output? — andrewsi, Aug 15 '13 at 17:18
string(5) "34.00" 34.00string(5) "37.00" 37.00 this if my query gets 2 results. I also use while (loop)! — user2635574, Aug 15 '13 at 17:28
@user2635574 - so. You're running this code in a loop? That should have been in your initial question. — andrewsi, Aug 15 '13 at 17:29
If you only want the lowest price why dont you just fetch the lowest price from your database in the first place? — Gordon, Aug 15 '13 at 17:32

Here's a short sample:

$array = array('lastname', 'email', 'phone');
foreach($array as &$value){
   $value = "'$value'";
}
$comma_separated = implode(",", $array);

I'm not quite sure what $data[Price] contains. If this is the value you get using var_dump, as you say:

NULL 37.00NULL 39.00NULL 45.00

You could do this:

$price = explode('NULL ', $data[Price]);
echo min($price);
