[PHP] Need help to understand a code

[Ashickur Rahman Noor]

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.
