Thanks for your response.

for ( $i = 1; $iparent_cost$i";
$tcc = "this->child_cost$i";
$cst = "cost$i";
if ( $this->;parent_cost1 > $this->child_cost1 ) {
$$cst = $$tpc;
}
else {
$$cst = $$tcc;
}
echo " cost: ".$cst;
}

I am at a loss as how to display the contents of $cst

for ($i=1; $i<$x; $i++) {
// put your loop code here
}

Where $x is the top limit. Of course you can modify these clauses to have something counting down instead of up etc. If that doesn't answer your question I'll need to know a bit more about what you're trying to do.

first of all thanks for nice site.

my question is, if it is possible access class variables with this method

i tried:

for($i=1; $i variable;

}

i don't get anything echoed
another this is, if the method you will post also can be used for class functions

THANKS for you answer

Yes you can. If you take the second code sample above but instead of giving $temp the value of "name".$i you would use "temp".$i and then assign $$temp the value of "name".$i or whatever you wanted to assign to it.

Then after the loop you'd have $temp1, $temp2 etc.

eg.


for ($i=1; $i < $num_fields; $i++) {
$temp = "temp".$i;
$$temp = "name".$i;
}


And then $temp1 equals name1, $temp2 equals name2 etc.

Is it possible to give '$temp' also a number?

So that you have:

$temp1 = "name".$i;
$temp2 = "name".$i;
$temp3 = "name".$i;
$temp4 = "name".$i;
…

I would like to use those variables also after the loop.
