Php flat file - data NOT being written?

Hi all,

I don't know why the data isn't getting written to my flatfile database but its not! Any help would be superb.
Thank you

The edit page looks like this:

<?php
$listings=file("bookings.txt");
$no_of_bookings=sizeof($listings);

for($i=0; $i<$no_of_bookings; $i++)
{
$details=explode("\t",$listings[$i]);
echo "<input type=\"text\" name=\"booking[$i][]\" value=\"$details[0]\">";
echo "<input type=\"text\" name=\"booking[$i][]\" value=\"$details[1]\">";
echo "<input type=\"text\" name=\"booking[$i][]\" value=\"$details[2]\">";
echo "<input type=\"text\" name=\"booking[$i][]\" value=\"$details[3]\">";
echo "<br>";
}
?>

Code (markup):

The save page looks like this:

<?php
$bookings="";
foreach($_POST["booking"] as $booking)
{
$bookingLine=implode("\t",$booking);
$bookings.=$bookingLine."\n";
}
$fh=fopen("bookings.txt","w+");
if(fwrite($fh,$bookings))
{
echo "Changes Saved successfully...";
}
else
{
echo "Failed to save changes...";
}
fclose($fh);
?>

<a href="switch.php">Click here for Admin Area</a>

Code (markup):

All that is appearing is Click here for Admin Area - nothing else....... please fix this as its something small?
Thank you all,

Found the issue - the save page was saved in unicode. I changed it back to ansi. Maybe this will help someone else out in the future.
