Looping variable returned as ""

[Anon]

This is my script...

<?php

include ("config.php");

$fh=fopen($newsidpage, "r");
$newsid=fread($fh, filesize ($newsidpage));
fclose($fh);

if ($repeat == "") {
$repeat=$newsid;
} else {
$repeat=$repeat;
}

$fi=fopen("$hlpg", "w");
fwrite($fi, "");
fclose($fi);

for ($i = 1; $i <= $repeat; $i++) {

$fh=fopen($hlpg, "r");
$hlinfo=fread($fh, filesize ($hlpg));
fclose($fh);

include ("$path$databasedir$newsid.txt");

$fi=fopen($hlpg, "w");
fwrite($fi, "<a href='view.php?nid=$newsid'>$subject</a> - $description<br>$hlinfo");
fclose($fi);

$newsid=$newsid-1;

}

?>

But, as the loop goes round, $hlinfo is always given as "" to the begining of the loop every time, even though the file contains information.

So. Even though the file $hlpg has information inside it written by the previous loop,

$fh=fopen($hlpg, "r");
$hlinfo=fread($fh, filesize ($hlpg));
fclose($fh);

always returns as "" (the file is cleared before the loop)

I just dont understand where im going wrong!

Try echoing filesize($hlpg), could be that the operating system is returning you a 0 (Windows especially can try to do things asynchronously and might not have finished writing the file before the next iteration).

All that opening, reading, and writing doesn't seem necessary anyway. Why not just build up the string inside the loop and write it once after the loop terminates?
