Hi all

I need some help to understand a code. The code is like this

$result = mysql_query($sSQL) or die("err: " . mysql_error().$sSQL);
     if($row = mysql_fetch_array($result))
                         {
       foreach($row as $key =>$value){ $$key=$value;}
     }


I don't get the code from the foreach loop.

I assume that you mean the meaning of "$$key = $value".
This is a variable variable[1]
This means if you have a key in your array named "dino" then you assign $dino the value of $value for the current row.

so: $key = 'dino', $value = 'saur'
=> $$key = $value => $$key = 'saur' => $dino = 'saur'

Hope this was somewhat helpful and understandable.
