problem w/ variables

[obennis]

I have this weird problem with my variables.

this is a snippet of my code:

$chkfile = $_POST['chkfile'];
print $chkfile; // it prints "file.ext"
if(preg_match ("/(\w+).(\w+)/i",$chkfile, $matches))
print "there is a match";
else

print "no match";

the output for this program is "no match"

this is a weird problem because it can be fixed like this:

$chkfile = "file.ext"

if(preg_match ("/(\w+).(\w+)/i",$chkfile, $matches))
print "there is a match";
else

print "no match";

the output for this program is "there is a match"

it seems like my $_POST is working fine since in the first prgram
when I print the variable $chkfile it prints 'file.ext', but if I tend to use that variable ($chkfile) in a function whether it is preg_match or whatever it loses its content

Are you sure that the $_POST[] does not have any other hidden/ non-printable characters in it.

You can check this by using a loop like

for ($x = 0; $x < strlen($_POST[]); $x++) {
     echo ord($_POST[][$x]) . "<br>";
}

Seems a little strange, but who knows.
