Question

My code is:

$query = "SELECT a.hash, a.full, a.partial, a.servers, a.lastupd, b.full, b.partial, b.servers, b.lastupd FROM table1 AS a, table2 AS b WHERE a.hash='".$hashcode."' AND a.hash=b.hash;";
$result = mysql_query($query);

then I perform a

print_r(mysql_fetch_array($result));

And I get this weird output:

Array
(
    [0] => blah
    [hash] => blah
    [1] => 1,1,1
    [full] => 0,1
    [2] => 1,2,1
    [partial] => 4,2
    [3] => srv1,srv2,srv3
    [servers] => srv2,srv3
    [4] => 0000-00-00 00:00:00
    [lastupd] => 0000-00-00 00:00:00
    [5] => 0,1
    [6] => 4,2
    [7] => srv2,srv3
    [8] => 0000-00-00 00:00:00
)

Why there’s data repetition for b table and doesn’t create an associative array with keys a.* and b.*?

Note: the timestamps set to 0 are correct

Answer 1

Because mysql_fetch_array returns both associative and numeric array. Use mysql_fetch_assoc, if you only need associative array.

(By the way, mysql is deprecated, read about using mysqli or PDO)
