Flat File Login

[tarun]

<?php
$user  =  $_POST["u"];
$pass  =  $_POST["p"];
$db = file("db.txt");

foreach($db as $key => $val) {
$data[$key] = explode("|-|", $val);
}

for($k = 0; $k < sizeof($db); $k++) { 
$u = $data[$k][0];
$p = $data[$k][1];

if ( $u == "$user" ) {
if ( $p == "$pass" ) {
echo 'You Are Now Logged In As: '.$u.'';
}
else {
echo 'Username And Password Do Not Match';
}

}

}
?>

 

Theres Still More To Add When Your Logged In Such As Sessions

But At The Moment I Can't Even Log In

I Get My Error "Username And Password Do Not Match"

You're "if" is incorrect, try:

<?php
if ( $u == $user && $p == $pass)
    echo 'You Are Now Logged In As: '.$u;
else
    echo 'Username And Password Do Not Match';
?>

 

BTW, what is the format of your input file? There may be an easier way of doing this.

By Input File Do You Mean The db.txt File

It Looks Similar To This

user1|-|pass1
user2|-|pass2

 

 

And With This "NEW" Code I Get:

Username And Password Do Not MatchUsername And Password Do Not Match

 

It Comes Out Twice Because There Are Two Columns Of Data (eg. Col1:user1 Col2:pass1)

Ok. Go back to your original "if" statement. I believe the problem is that you're not trimming off the newline character from the end of the input lines before you do the compare. Change:

<?php
foreach($db as $key => $val) {
$data[$key] = explode("|-|", $val);
}?>

to

<?php
for ($i=0;$i<count($db);$i++)
$data[] = explode("|-|", trim($db[$i]);
?>

 

Here is my version of your code that I tested to make sure it worked:

<?php
$user  =  $_POST["u"];
$pass  =  $_POST["p"];
$data = array();
$db = file("db.txt");

for ($i=0;$i<count($db);$i++)
$data[] = explode("|-|", trim($db[$i]));

for($k = 0; $k < count($data); $k++) { 
if ( $data[$k][0] == $user )
	if ( $data[$k][1] == $pass )
		echo 'You Are Now Logged In As: '.$user;
	else
		echo 'Username And Password Do Not Match';
}
?>
