Return a loop in function php

Question

Is it possible to return a loop? not the result but the loop it self. I want to create a function in php. For example like this.

function myloop($sql){
$quer

No, but you could do

function loopdate($sql,$code)
{
 $query=mysql_query($sql)
 while (mysql_fetch_assoc($query))
 {
  eval($code);
 }
}

However - eval is rediculously dangerous its really really discouraged.

function loopdate($sql,$function)
{
 $query=mysql_query($sql)
 while ($data=mysql_fetch_assoc($query))
 {
  $function($data);
 }
}

would be better.

myfunc($data)
{
 foreach ($data as $key->$value)
 {
  print "".$key."".$value."\n";
 }
}

So you can call

loopdate("select * from mytable","myfunc");
