I am reading a set of strings in from a file, which are separated by
newlines. When I compare the variable to the string it returns that
the string is not equal, even though by appearance it is. I am sure
that there are some non displayable characters in there, but don't
know how to fix this.
Here is some sample code
The other file is just a form and I know it's working fine.
<?php
$file = fopen("pass.txt", "r") or exit("Unable to open file");
$auth = filter_var($_POST["auth"], FILTER_SANITIZE_STRING);
while (!feof($file)) {
$current_Line = fgetss($file);
filter_var($current_Line, FILTER_SANITIZE_STRING)
if (strcmp($current_LIne, $auth) == 0) {
setcookie("auth", "true", time()+3600);
echo Success;
}
}
echo Done;
?>
<html/>
As you can probably see, I'm struggling.

I did some text processing on mail files. Sometimes the text is utf-8
which is encoded differently inside variables. You can either strip the
8th bit off each byte, which filter_var() is doing. Try var_dump() on
the string to see what's actually in there.

Try:
$current_Line = trim(fgetss($file));

I appreciate everyone's help. The problem was an extra space at the
end of the string so trim should work too. This is the resulting code
and it works, for anyone that tries this in the future.
<?php
$options = array ('flags' =>
FILTER_FLAG_STRIP_LOW ,FILTER_FLAG_STRIP_HIGH);
$file = fopen("pass.txt", "r") or exit("Unable to open file");
$auth = filter_var($_POST["auth"], FILTER_SANITIZE_STRING, $options);
while (!feof($file)) {
$current_Line = fgets($file);
$current_Line = filter_var($current_Line, FILTER_SANITIZE_STRING,
$options);
if (strcmp($current_Line, $auth) == 0) {
setcookie("the", "true", time()+3600);
}
}
echo Done;
?>
