Fetch Value in reverse order using while loop - php

Question

I have a code which retrieves the values from data base.but i want to fetch this values in reverse order.See this example
While($row=mysql_fetch_assoc($rs)){
echo $row['id']."<br>";//gives 1 and 2 and so on
echo $row['val']."<br>";// gives abc and def and so on
}
But i want
2
def
1
abc
How could i do this .i don't wanna use the Query for this like use of ORDER BY.so can i control this at PHP End??

Answer 1

while($row = mysql_fetch_array($rs)){
$data[] = $row;
}
$data = array_reverse($data,true);
while($data){
}
Haven't tested it though
I tested it in this site and it works. Here's the snippet I used:
$data = array(1 => array("foo" => "bar"), 2 => true);
$data = array_reverse($data,true);
print_r($data);
Edit:
Using your edited answer, I got this:
$data = array(1 => array(1, "abc"), 2 => array(2, "def"));
$data = array_reverse($data,true);
foreach($data as $d){
echo "id>".$d[0]." | val>".$d[1]."<br />";
}

Answer 2

Store your data in an array (in your while-loop). After that, you can use array_reverse to reverse item order.

Answer 3

You can also use a cursor that iterates through your result set -moving backwards and forwards - using something like PDO - and probably similar variations for each other type of connection:
cursor_orientation
For a PDOStatement object representing a scrollable cursor, this value determines which row will be returned to the caller. This value must be one of the PDO::FETCH_ORI_* constants, defaulting to PDO::FETCH_ORI_NEXT. To request a scrollable cursor for your PDOStatement object, you must set the PDO::ATTR_CURSOR attribute to PDO::CURSOR_SCROLL when you prepare the SQL statement with PDO::prepare().
But using an array_reverse might be simpler. Having said that, ordering the data in the query would be simpler again (and probably much more efficient).

Answer 4

$result = $mysqli->query($query);
for($i = $result->num_rows - 1; $i>0; $i--){
$result->field_seek($i);
$finfo = $result->fetch_field();
echo $finfo->id;
echo $finfo->val;
}
