Re: [PHP] cant get if logic correct..
is_integer probably wouldn't work, since you're dealing with strings here.
Your best friend here would probably be 'is_numeric' which would return true
on both the string '1' as the integer 1 true. As well as 1.1 and '1.1'. The
only one solution I could think if would be:
preg_match('/^\d+$/', $stnr);

Ain't it always the small things like this that consume too much time?

RE: [PHP] cant get if logic correct..
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: [PHP] 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
}
}
