RTFM:
mysql_fetch_array():
1. Returns a single row from the result, use a while loop to get all =
result.
2. Returns a both numerically and associative array by default. Either u=
se =
the constants MYSQL_NUM or MYSQL_ASSOC, or the function mysql_fetch_row(=
) =
or mysql_fetch_assoc() respectively if this isn't desired behaviour.
$result =3D mysql_query($sql);
$set =3D array();
while($row =3D mysql_fetch_assoc()) $set[] =3D $row;
print_r($set);
