a cool way to use eval is to convert strings into variable names.
this is a subsitute for using arrays.
look at this code:
<?php
for($a=1; $a<=5; $a++){
eval("variable".$a."=".$a.";");
}
?>
this will create variables called variable1, variable2, and so on, that are equal to 1, 2, and so
on.
i recently used this to help a friend make a Flash game that sent variables like that to PHP.
