Thank for your reply BUT the solution you proposed me does NOT apply, because eval() is for evaluating strings as if they were codes, moreover the somescript.php would have to be readapted : please note that the script takes the arguments via argc (commandline arguments). Eval() is not suitable for running external (and may be big) script file which takes in input the arguments via $HTTP_SERVER_VARS['argv']; otherwise I would have used include() !! The problem is open: the behaviour that I stated below is very strange... could not understand why...
