setup your checkbox something like this:
<input type="checkbox" name="delete[]" value="<?=$row[0]? />
php will treat this as an array

The closing php tag and quote of the value attribute was missing:
<input type="checkbox" name="delete[]" value="<?= $row[0] ?>" />

| Actually I want to know how to access the variable
after defining it.
Like :
$query="delete from feedback where id=$delete[$i]";
$deleteresult=mysql_query($query) or
die("Unable to delete");
But here I am not getting any value in
"$delete[$i]"-(here $i is 0,1,2,3)
So what to do to access it ?
I cant access the value even by $_POST['$delete[$i]']
Can any of you suggest me the sollution ?

| Well, IMHO you shouldn't do in-string variables as you never know if
it will work. In this case, it won't YOu should do something like
this:
$query='delete from feedback where id='.$delete[$i];
Single quotes tell PHP not to look for variables in the string. A
period concatenates. There's actually a better solution, too:
$query='delete from feedback where
id="'.mysql_real_escape_string($delete[$i]).'"';
