How to add various operations in this change? you can add operations in the while loop, and add operations in the foreach loop.

Reply to discussion (solution)

When I output an entry, isn't it enough?

How to do it? I just learned, while

While ($ arr = mysql_fetch_array ($ res) {?>"> Edit"> Delete

How can I add an output?

Have you added the above?

That is wrong. The program uses the foreach loop instead of the while loop.

Foreach ($ arr as $ value ){
Echo"";
Echo"";
}
?>

Foreach ($ arr as $ value ){
Echo"";
Echo"";
}
?>
The one above is wrong.
If your assoc only has ID, add $ value directly. Otherwise, you should know how to do it.

 
 "; Foreach ($ arr as $ k => $ v) {if (isset ($ arr2 [$ k]) & is_array ($ arr2 [$ k]) {echo"
$ K $ v & nbsp edit and delete "; for_category ($ arr2 [$ k], $ arr2); echo"
";} Else {echo"
$ K $ v modify and delete popular groups ddd & nbsp
";}} Echo"";} For_category ($ tree [0], $ tree);?>
 "; Foreach ($ arr as $ k => $ v) {if (isset ($ arr2 [$ k]) & is_array ($ arr2 [$ k]) {echo"
$ K $ v & nbsp edit and delete "; for_category ($ arr2 [$ k], $ arr2); echo"
";} Else {echo"
$ K $ v modify and delete popular groups ddd & nbsp
";}} Echo"";} For_category ($ tree [0], $ tree);?>

// The real effect is as follows: create an infinite classification and use recursive calling.

Cannot join links between them.

Echo"

$ K $ v modify and delete popular groups ddd & nbsp

";
Double quotation marks must be escaped!
Echo"

$ K $ v modify and delete popular groups ddd & nbsp
