Question

I have a foreach() method where a message for an email is concocted:

foreach($this->fields as $key => $field)
            $msg .= "$key :  $field \n";

My problem is that I need to create a mysql_query() to insert the field values into my database and I don’t know how I can retrieve that data to actually insert into the database.

How can I get it?

Let me know what other code I need to provide if you need any more.

You can’t create a dynamically named variable inside a foreach loop. What you can do, though, is create an array of keys with $field as the value:

$keys = array(); $i = 0;
foreach($this->fields as $key => $field){ 
   $keys[$i] = $field; $i++;
}

However, this is kind of roundabout, because you can just get the same behavior by getting it like this:

$this->fields[$key] // will return $field

I hope I understood your question correctly through your comments.
