Why don't you try to check for if it is integer. You will get the function
to check the variable (is_integer not sure) in manual.

Subject:  cant get if logic correct..

Hi
i have a piece of code that gets info from a comma delimited file,
then gets each value that is to be insterted into the database ....

The variabls must only contain numbers and must not be null ..
but the  logic i have is iether not working or there are some hidden
characters creeping in because it is processing the data ... how can i
do this better ?


for($i=2;$i<$arrsize;$i++){
		  $parts=explode(",",$lines[$i]);
                                  $stnr=$parts[0];
		  $subj=$parts[1];
		  $mark=$parts[4];
		if (($stnr>"") and ($subj>"") and ($mark>"")){
                                   //do alot of something lol
                                   }
                               }
