Question

While working with PHP ,handling connection’s with Database (MySQL)

$result = mysql_query('select * from products');
$row = mysql_fetch_array($result);

And yesterday founded out that array $row had Duplicate data within.

First you have Data’s selected from database arranged in Indexes like : $row[0] = ID; than you also could find $row['ID'] = ID.

So is this only a feature of the Framework ,which copies data Virtually or are these Data’s stored twice in array .

Answer 1

Straight from the manual:

mysql_fetch_array — Fetch a result row as an associative array, a
numeric array, or both

The prototype of the function says that

array mysql_fetch_array ( resource $result [, int $result_type = MYSQL_BOTH ] )

meaning that it returns both arrays by default – that is – duplicating the info
