arrays !!!! not simple variables!
Reply:Try making an array instead of 100 variables. Something like this:





$a[]='blue';


$a[]='red';


$a[]='black';





for ($i=0; $i %26lt; count($a); $i++)


{


echo '%26lt;td%26gt;' .$a[$i] . '%26lt;/td%26gt;';


}
Reply:Instead of 100 variables, use one array with 100 elements. Then you can reference a[0]..a[99]. Check your manuals / reference material or search the net on how to declare and use arrays.
