RE: [PHP] unexpected array_diff output

Hello there !
I am trying to fill and then compare two arrays: one

I check both with a print_r to be sure that both are correctly filled
(which seems to be the case). But then, when I try to compare
them with
a array_diff , the result is incoherent (at least to me...). I have
tried several variant, but I don't understand what's wrong. Sure you
guys can tell me where is my mistake.
Here is the code:
?
// creates first array (from a _POST[''] )
foreach ($_POST['input_auteur'] AS $aut_ligne) {
$part_ligne = explode(,,$aut_ligne);
$arr1[] = (string) $part_ligne['2'];
}
echo Array from POST :;
print_r ($arr1);
I don't have any great insight into what appear to be your odd array_diff()
results, but try using var_dump() instead of print_r() -- it will give you
more information about *exactly* what values are stored in the arrays, and
it may just be that you'll spot an odd discrepancy.
Cheers!

Thanks, Mike ! That was the correct answer. In one of the array there
was always a space in front of the digit (ex: 2). The comparison
was then corrupted because of this. I never used var_dump() before, but
it is far more precise. Thanks for the hint!
Thanks to you too, Thorsten for your kind help.
Best regards,
Fred
