Using your script and postgres, with PGSQL_ASSOC in fetch_array:
fetch_assoc(): 1.62810707092 seconds [18880 rows](1066665580.0.52192900 :
1066665578.89)
fetch_array(): 1.54432892799 seconds [18880 rows](1066665582.0.06938900 :
1066665580.53)
second time:
fetch_assoc(): 1.45861208439 seconds [18880 rows](1066666481.0.87854800 :
1066666480.42)
fetch_array(): 1.46833896637 seconds [18880 rows](1066666483.0.34997600 :
1066666481.88)
Maybe fetch_assoc() is not so much faster than fetch_array()...
:) yes I have also 18880 rows
The code:
include('../include/db.php');
$sql = "select * from items";
list($l,$r) = split(" ",microtime());
$start = $l + $r;
$r = pg_query($db, $sql);
$num = pg_num_rows($r);
while( $row = pg_fetch_assoc($r) ) {
// echo "";
}
list($l, $r) = explode(" ",microtime());
$diff = ((float)$l + (float)$r) - (float)$start;
echo "<hr/>fetch_assoc(): $diff seconds [$num rows]($r.$l :
$start)<hr/>";
list($l,$r) = explode(" ",microtime());
$start = ((float)$l + (float)$r);
$r = pg_query($db, $sql);
$num = pg_num_rows($r);
while( $row = pg_fetch_array($r, NULL, PGSQL_ASSOC) ) {
// echo "";
}
list($l, $r) = explode(" ",microtime());
$diff = ((float)$l + (float)$r) - (float)$start;
echo "<hr/>fetch_array(): $diff seconds [$num rows]($r.$l :
$start)<hr/>";
