storing a while loop in a variable

[supermanjnk]

Is it possible to store a while loop in a variable?

for instance

$while = while ($this = $that) {
echo "test";
}

Not the loop itself, but you can use the loop to collect its "output":

while($this==$that) {

$result++;

$loop .= $result.",";

}

echo $loop;

You can also assign the data to an array for later manipulation:

$loop = array();

while($this==$that) {
$result++;
$loop[] = $result.",";
}

echo $loop[0];

or maybe you can tell what do you expect the while loop to return and sombody will tell you another way of getting that result.....

supermanjnk, are you trying to set up a page with a bunch of data-dependent while loops, and then grab the appropriate one for use in a more generic page? Like using a stored procedure in SQL?

I think SS gave you your answer in the first post, but if the answer to his last question is "yes", then in fact, you can store a while loop in a variable.

$while_loop = ' 
   while ($this == $that)  
   { 
     echo "test" ; 
   } ' ;  
eval($while_loop); 

Note that you probably want to use the comparison op (==) and not the assignment op (=) in your while loop.

Yea I will actually be using
$this = mysql_fetch_object($that)
