For example I have the code
$query="Select * from table order by id";
$res1=mysqli_query($link,$query);
while($row=mysqli_fetch_array($res1)) {
echo $row['Id'];
}
echo '<br>';
$query="Select * from table order by user";
$res1=mysqli_query($link,$query);
while($row=mysqli_fetch_array($res1)) {
echo $row['Id'];
}
It is possible to do this without second query and without use of array and foreach
, to change orders of row in resul1
from first query to get order like in second query.
You can easily order by several fields at one time:
$query = "SELECT * FROM table ORDER BY id, user ";
$res1 = mysqli_query($link,$query);
....
you can achieve this by passing a php variable in the mysql query.
$query="Select * from table order by $order";
and set $order as you want.
$query = "SELECT * FROM table ORDER BY id, user ";
This will order your data first by id and then user.
You can change order of results in PHP.
