Basic PHP login system - help!

[The Frederick]

I'm making a basic login system, where you register and it writes your username and password to a .dat text file. For the love of me, I can't make it write the info and then move to the next line for the next registration. Here's my code:

 

<?php

 

$file1 = fopen("users.dat", "r+");

 

if ($file1) {

 

$found = 0;

$id = 1;

 

while (!feof($file1)){

$row = fgets ($file1, 1024);

$parts = preg_split ("/::/", $row);

 

if ($parts[0] == $_POST){

$found = 1;

}

} //end for

 

if ($found == 1){

echo "Email address already registed. Please try another another email address";

}

else{

 

$file2 = fopen("userid.dat", "r");

$id = fgets ($file2, 1024);

$id += 11;

fclose ($file2);

 

$file2 = fopen("userid.dat", "w");

fwrite($file2, $id);

fclose ($file2);

 

echo "New account created.";

$newaccount = $_POST."::".$id."::".$_POST[newpassword]."\n";

fwrite($file1, $newaccount);

}

 

fclose ($file1);

 

} // end of if statement

 

?>

 

That "\n" seems to be completely useless. Any ideas?
