Variable within a variable

[micmac]

Hi guys,
I have the following code:

$old_num = 1;
while ($old_num <= $total_pos){
    echo "$last_name$old_num<br>";

$old_num++;
}

Now, lets assume that $total_pos = 6 and that $last_name is a value from the mySQL database.
My question is how can i get $last_name to be $last_name1, $last_name2 etc when echoed?

Cheers,
micmac

You'd need to use a for loop.

lets say you have

$row = mysql_fetch_array($query)

Then you'd use a for loop that looked like this to loop through the results

for ($i=0; $i <= $total_pos; $i++){
    echo $last_name[$i] . "<br>";
}

I started with 0 instead of 1 like you did because the first array key is 0, not 1.

That should do the trick also..
-OR-
echo "<br>$last_name" . $old_num;
