can someone help me with php file i/o

[errigour]

I am using fputs to print some lines to a file but It doesn't include the end of line
character at the end of the string so the strings are all written to the top line.
how can I add eol to the end of a string printed to a file.
also how can I read each line of a file by using eol to end the string I want read.

fputs() simply prints the string to the file. If the string does not have a newline in it, no newline will be written to the file. So there are two solutions:

1) Add a newline to the end of the string that you are printing
2) Explicitly print a newline to the file after the string:

fputs($fp, "\n");

Reading a line from a file is done by using the fgets() function:
PHP: fgets - Manual

Can you please post the code?

I'd suggest using the pre-defined constant PHP_EOL instead of '\n' as it is definitely more readable to my eye. If you are developing on Windows and deploying on Linux (or visa versa) then it's pretty much essential.

While you guys are here is there a more resourceful way too use the fputs that is already being used?
I was wondering if I could do

fputs($handle, $_POST["username"]."\n");

Heres a copy of the code

<?php
session_start();
if ($_SESSION['id_num'] <= 0)
{
    $_SESSION['id_num'] = rand();
}

if (!$_POST["username"])
{
    echo "<p style=\"color:red;font-weight:bold;margin-left:95px\">";
    echo "* A username is required</p>";
    include("account creation.html");exit;
}
else
{
/*
    $username         = $_POST["username"];
    $password         = $_POST["password"];
    $passwordvar      = $_POST["passwordvar"];
    $firstname        = $_POST["firstname"];
    $middlename       = $_POST["middlename"];
    $lastname         = $_POST["lastname"];
    $streetaddress    = $_POST["streetaddress"];
    $aptnumber        = $_POST["aptnumber"];
    $streetaddresstwo = $_POST["streetaddresstwo"];
    $city             = $_POST["city"];
    $state            = $_POST["state"];
    $zipcode          = $_POST["zipcode"];         */

    if ($_POST["password"] != $_POST["passwordvar"])
    {
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
        echo "Password's are not the same</p>";
        include("account creation.html");exit;
    }
    else
    {

        $syslog = fopen(",/system", "a");
        if(file_exists("database/".$_POST["username"]))
        {
            echo "<p style=\"color:red;font-weight:bold;margin-left:95px\">";
            echo "The username you entered already exists</p>";
            include("account creation.html");exit;
        }
        else
        {
            if (!$handle = fopen("database/".$_POST["username"], "w+"))
            {
                fputs($syslog, "Unable to open database/".$_POST["username"]);
                echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
                echo "Password's are not the same</p>";exit;
            }
            else
            {
                if($_POST["username"]){fputs($handle, $_POST["username"]);}
                if($_POST["password"]){fputs($handle, $_POST["password"]);}
                if($_POST["passwordvar"]){fputs($handle, $_POST["passwordvar"]);}
                if($_POST["firstname"]){fputs($handle, $_POST["middlename"]);}

                if($_POST["zipcode"]){fputs($handle, $_POST["zipcode"]);}
                fclose($handle);
            }
        }       fclose($syslog);
        include("redirect.php");
        echo "<p style=\"color:red;font-weight:bold;margin-left;95px\">";
