As you know, while loops will execute as long as a condition is true. The first one says while you can assign $row from mysql_fetch_assoc it can continue. When an array reaches its end you will not be able to assign it, making the while loop end. Mysql_fetch_assoc returns an array, so you can apply foreach to $row.

The syntax of foreach is
foreach($arr as $key => $value)

So the following code represents the values.

PHP Code:


			
$arr["key1"]  = 7; //$key=key1 $value = 7
$arr["key2"] = 15; //$key=key2 $value = 15
$arr["ABC"] = 23; //$key=ABC $value = 23
