My MySQL server site is down so I couldn't make a highscores database in MySQL, which would be a lot easier. I am not that good at PHP since I just started learning the day before yesterday so just please help me.

 

I've been trying to create a PHP highscores database w/o the use of MySQL. It currently has 3 scripts to it, a create.php with parameters data and pass, a add.php with parameters data, pass, name, and score, and a display.php with parameter data. I have some trouble displaying the scores in a list from .dat files you create. It used to work. I also have some trouble adding new names tagged with their scores. Please help!

 

 

Below are the 3 scripts:

 

display.php
<html>
<body>

<?php
if (!isset($_REQUEST["data"]))
exit("Invalid highscores data name!");
if (file_exists($_REQUEST["data"].".dat"))
$file = fopen($_REQUEST["data"].".dat","r") or exit("Unable to load highscores!");
else
exit("Highscores data doesn't exist!");

if (file_exists($_REQUEST["data"].".dat2"))
$file2 = fopen($_REQUEST["data"].".dat2","r") or exit("Unable to load highscores!");
else
exit("Highscores data doesn't exist!");

$place=0;
$pss=fgets($file);
echo $pss;

while((!feof($file)) && (!feof($file2)))
  {
  $place++;
  $name=fgets($file);
  echo $name;
  $score=fgets($file2);
  echo $score;
  if(($score!="") and ($name!=""))
echo $place."-".$name." ".$score."<br>";
  }
  
fclose($file);
fclose($file2);
?>

</body>
</html>

 

create.php (This works fine)
<html>
<body>

<?php
if (!isset($_REQUEST["data"]))
exit("Invalid highscores data name!");
if (!isset($_REQUEST["pass"]))
exit("Invalid highscores data password!");

if (!file_exists($_REQUEST["data"].".dat"))
$file=fopen($_REQUEST["data"].".dat","x") or exit("Unable to create highscores data!");
else
exit("Highscores data already exists!");

if (!file_exists($_REQUEST["data"].".dat2"))
$file2=fopen($_REQUEST["data"].".dat2","x") or exit("Unable to create highscores data!");
else
exit("Highscores data already exists!");

fwrite($file,$_REQUEST["pass"]);

fclose($file);
fclose($file2);

echo "Highscores data with name, ".$_REQUEST["data"].", and password, ".$_REQUEST["pass"].", created successfully!"
?>

</body>
</html>

 

add.php
<html>
<body>

<?php
if (!isset($_REQUEST["data"]))
exit("Invalid highscores data name!");
if (!isset($_REQUEST["pass"]))
exit("Invalid highscores data password!");
if (!isset($_REQUEST["name"]))
exit("Invalid entry name!");
if (!isset($_REQUEST["score"]))
exit("Invalid entry score!");

if (file_exists($_REQUEST["data"].".dat"))
$file = fopen($_REQUEST["data"].".dat","r") or exit("Unable to load highscores!");
else
exit("Highscores data doesn't exist!");

if (file_exists($_REQUEST["data"].".dat2"))
$file2 = fopen($_REQUEST["data"].".dat2","r") or exit("Unable to load highscores!");
else
exit("Highscores data doesn't exist!");

if($_REQUEST["pass"]!=fgets($file))
{
fclose($file);
fclose($file2);
exit("Incorrect password for highscores data, ".$_REQUEST["data"]."!");
}

$place=0;

while((!feof($file)) && (!feof($file2)))
  {
  $place++;
  $scr=fgets($file2);
  if($scr<$_REQUEST["score"])
break;
  }
  
fclose($file);
fclose($file2);

$file = fopen($_REQUEST["data"].".dat","r+");
$file2 = fopen($_REQUEST["data"].".dat2","r+");

$read = file($_REQUEST["data"].".dat");
$read["Set"]=$_REQUEST["name"];
fwrite($file,$read[0]."
");
for($s=1;$s<place;$s++)
{
fwrite($file,$read[$s+1]);
}
fwrite($file,$read["Set"]."
");
for($s=place+1;$s<=count($read)-1;$s++)
{
fwrite($file,$read[$s+1]);
}
fclose($file);

$read = file($_REQUEST["data"].".dat2");
$read["Set"]=$_REQUEST["score"];
for($s=0;$s<place-1;$s++)
{
fwrite($file2,$read[$s]);
}
fwrite($file2,$read["Set"]."
");
for($s=place;$s<=count($read)-2;$s++)
{
fwrite($file2,$read[$s]);
}
fclose($file2);

include("display.php")
?>

</body>
</html>

 

If you have any better way to make this, PLEASE tell me, thank you!

your sql server is down so you opt to make a flatfile solution instead of fixing the server?

 

Yea, but I can't fix the server since I don't have access to it. It is down for maintenance. So, uhh, can you solve the bug? I've been trying to fix it for hours already...

So...you just started learning php 2 days ago, and yet managed to master it enough to come up with all that?  And what about that "It used to work" statement?  Since you just started php 2 days ago, did it used to work, what, yesterday?

Like a couple hours ago, somehow, it was working, but that was b4 I created the other 2 scripts, then I edited it a little, and it went kaploosh... Plus, PHP isn't that hard, and I didn't master it, my creations don't work...

 

EDIT: @Maq

The bug is in the scripts, I've been using another server for executing my php files, so please, just help me fix the scripts.

if (!file_exists($REQUEST["data"]))
  exit("Highscores table, ".$REQUEST["data"]." doesn't exist!")

 

Please help me fix this, it says some error in the if part.
