Mysql error echoing the variable -


i have mysql query below - 

    $id_order_last="15";     $id_order[]=array();     $sql1="select * `ps_orders` `id_order`>      $id_order_last  order `id_order`";     echo $sql1;     $result1= mysql_query($sql1);     $cnt=1;     while ($row = mysql_fetch_array($result1))     {         /*$id_order[$i]=$row['$id_order'];*/         echo $row['$id_order']."<br />";         $cnt++;         echo $cnt."<br />"; }

as can see have $id_order_last set 15 displaying value 15 when echoed. check sql echoed , display 

select * `ps_orders` `id_order`> 15 order `id_order`

so in sql, run in phpmyadmin , tuples returns correct value. show result means 17 , 18 in database. means query correct!

then echoed 2 , 3 cnt++ value while $row['$id_order'] still empty <br /> shown space.

though tried loop print whole things still not showing up?

$i=1; for($i;$i<=$cnt;$i++) {     echo $id_order_last."<br />";     echo $id_order[$i]."<br />";     $id_order_last=$id_order[$i]; } 

use echo $row['id_order'] in place of echo $row['$id_order']  remove $.
