I am trying to use php to verify my html form a file.txt in witch i have a login , password. the problem in my php code that even when the variables are equal i get false when i compare them.The only exception is when i compare the first login and pasword i get true for both.
Here is my code to clarify my problem. so my html form calls this php page code.
<?php
echo " begin <br/>";
$name=$_GET['username'];
$password=$_GET['password'];
echo "$name <br/>";
echo "$password <br/>";
$f = fopen("file.txt", "r");
$res="0";
while(!feof($f))
{ echo "begin while <br/> ";
$p3=fgetc($f );
while($p3!="|" && !feof($f) )
{
$user1=$user1.$p3;
$p3=fgetc($f);
}
$p1=fgetc($f);
while($p1!="|" && !feof($f))
{ $pass=$pass.$p1;
$p1=fgetc($f);
}
$p2=fgetc($f);
while($p2!="|" && !feof($f))
{
$q=$q.$p2;
$p2=fgetc($f);
}
var_dump($user1 == $name);
var_dump($password == $pass);
echo "<br/> $user1 <br/>";
echo "$pass <br/>";
echo "compare <br/>";
echo "$name <br/>";
echo "$password <br/>";
if( $name == $user1 && $password == $pass )
{ echo "succeeded <br/>";
echo "droit: $q <br/>";
echo "$res <br/>";
$res="1";
echo "$res <br/>";
break 2;
}
unset($p3);
unset($p1);
unset($p2);
unset($user1);
unset($pass);
unset($q);
}
fclose($f);
if($res == "1")
{ echo "ok <br/>";}
else
{ echo " error <br/>";}
echo " fin <br/>"
?>
