How: Compare entered PW to a PW data file
Uggh!!!!
I may be going about this all wrong.
My goal is to write a password protection script.
I’m a newbie to PHP, so be gentile.
I’ve written the file successfully,
now I’m trying to read from the file, however, I’m not sure how to compare the entered username (UN) & password (PW) with the UN/PW in the data file.
I can get the data to display with the following script, however,
I’m feeling kinda lost, disoriented, and a little green around the gills.
Can anyone help, or should I just drink the Koolaid?

<?php
function ReadFromFile () {
$TheFile = “wmdata.txt”;
$Open = fopen ($TheFile, “r”);
if ($Open) {
print (“Data currently listed in the data file:<P>n”);
$Data = file ($TheFile);
for ($n = 0; $n < count($Data); $n++) {
$GetLine = explode(“t”, $Data[$n]);
print (“$GetLine[0]<BR>n$GetLine[1]<P>n”);
}
fclose ($Open);
print (“<HR><P>n”);
} else {
print (“Unable to read from data.txt!<BR>n”);
}
}
?>

<?php
function check_login($name, $password)
{
$TheFile = "wmdata.txt";
$Data = file($TheFile) or die("Unable to read user data file.");
foreach($Data as $line)
{
$GetLine = explode("t", rtrim($line));
if($GetLine[0] == $name and $GetLine[1] == $password)
{
return(TRUE); # found it
}
}
return(FALSE);
}
### sample use, assumes login form has fields "login" and "password":
if(check_login($_POST['login'], $_POST['password']))
{
# valid login, so procede as desired
}
else
{
# invalid login, so display error message or other error handling process
}
?>
[/code]
