[SOLVED] fread not working right

[anolan13]

Hi everyone,

 

I'm trying to make a fairly simple login system based off of a couple bits of code and its not working right, hope you can help...

 

So the page before I make a session after the person registers successfully with logname which is just the name he logged in with, I also write a text file with the contents being that same logname. Here's my code on the protected page.

 

$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
session_start();
if (@$_SESSION['logname'] != $theData)
{
header("Location: http://mywebsite.com/login.html");
exit();
}

 

If I echo command $theData I see what it's contents are. If I type in $theData as the persons logname  directly it works correctly and allows the rest of the page to run. But for some reason it won't accept this block of code, it keeps kicking me back to mywebsite.com/login.html.

 

I'm very confused, please help!

 

Thanks

Try adding this line just before your "if" statement:

 

print "Logname: " . urlencode($_SESSION['logname']) . ", thedata: " . urlencode($theData); exit(0);

 

Do they match exactly?

results

 

Logname: 5, thedata: 5%0A

 

So where did it get 5%0A???????? How come when I echo its exact? What to do?

That's a "newline" character.  It shows up in echo as an actual new line, so that's why you don't see it.  The easiest way to deal with it is to use trim() on your data from fread().  trim() will remove spaces, newlines and some other invisible stuff from the start and end.
