PHP-Script deletes lines in .dat file
Question
I'm struggling with the following problem since 9 hours and can't find the solution. I'm using a very old script from here ( http://www.teralaser.net/invitephp/ ) to build an invitation-script. I already did all the styling within the past week and it looks great, now. the script stores the single datasets in a .dat file. Now I realized, that it always keeps just the first 125 lines of the database and deletes the rest. That's a hug he problem, as it is for an invitation with nearly 1000 persons. After some hours I found out (better I guess), that it's the following line, which destroys it:
case "adminadd":
if (isset($_POST["pwd"])) $pwd = $_POST["pwd"];
else $pwd="";
$pwdchk = 1;
if (isset($_GET["pwd2"])) $pwdchk = strcasecmp(md5( date("z") . $admin_password),$_GET["pwd2"]);
if (strcasecmp($pwd,$admin_password) != 0 && $pwdchk != 0) {
echo "<HTML><HEAD><META HTTP-EQUIV='REFRESH' CONTENT='1; URL=$PHP_SELF?do=admin'></HEAD><BODY bgcolor='#ffffff'><CENTER><H2>Falsches Passwort!</H2>Bitte warten...</CENTER></BODY><HTML>";
exit;
}

$r = $record[$i];
$row = explode("|~~|",$r);
$chkmail = $row[2];
if ($row[4] == "Gastgeber") $hostemail = $row[2];
for($j = $i+1; $j < $jmlrec; $j++) {

I'm looking forward for some ideas. I'll love to invite you for a coffee... ;) I can also send the whole script, if someone is interested.
Best!

EDIT: I'm still totally lost in the code, so I want to share the other parts of the code with you and maybe someone finds the problem. ;) Thanks!

It would appear that updated entries are marked by prepending them with ! . This loop appears to only be saving the updates, not every record.
Perhaps there was a typo - fopen with mode "w" will truncate the data file at 0 bytes before writing, if only the updated records are to be written, shouldn't that be mode "a" to append them to the existing file?
It is likely there is also a limit on how large a data file is allowed to grow, make sure you have set it large enough to allow 1000 records.
