Function Help

[tberger]

I am stuck.

I have a login form where a person will enter the email and password for their account. The data is being stored in a registereduser.txt file. Each item is seperated with a colon. The data is written in to the file

fwrite ($fp, "$email:$pw:$fname:$lname\n");

This is working fine.

What I am trying to create is a function that will take what they enter on the login page and check the information in the txt file to confirm the login information. My initial problem was that it never found a match even when there was some. So I checked to see if it was reading the file and it is. Now I am getting an error at the foreach() function I am using and then it does not find a match and the code ends. Here is the result I am getting:

[e-mail]:test:Tracy:seebe [e-mail]:test:Jane😃oe [e-mail]:test:TJ:Kay
Warning: Invalid argument supplied for foreach() in /staff/seebetra/homepage/ciss225/library.pinc on line 14
Sorry, you didn't match!

Here is the function:

<?php
function getLogin($username, $pass)
{
$username = trim($POST['email_address']);
$pass = trim($POST['password']);

$file = "/staff/seebetra/homepage/ciss225/registered_users.txt";
$fp = fopen($file, 'r');
$lines = fread($fp, filesize($file));
echo $lines;

foreach($lines as $line)
{
list($email_address, $password, $first_name, $last_name) = explode(":", trim($line));
$logged = FALSE;
echo $email_address;
echo $password;
echo first_name;
echo $last_name;

if($username == $email_address && $pass == $password)
{
echo "Hello ".$first_name." ".$last_name."!";
$logged = TRUE;
break;
}
}
if(!$logged)
echo "Sorry, you didn't match!";

fclose($fp);
}
?>

Any insight to get me through this would be very much appreciated!

fread does not return an array, and as such you cannot use foreach on it's results. You may need to [man]explode[/man] your lines by the separators to get the results into an array,

Ok - that makes sense. I just don't understand how to write the explode code when referencing a file - the examples I see all work off a string list.

I tried the following code

$lines = explode(":", $fp);

and now get the following when I try to process the login

ArrayResource id #4first_nameSorry, you didn't match!

Any suggestions?

I think tberger is referring to something like this:

$data = file_get_contents($file);
$lines = explode("\n", $data);
foreach ($lines as $line) {
	list($email_address, $password, $first_name, $last_name) = explode(":", trim($line));
	//...
}
