PHP 5.4.4-TS-VC9 on Windows XP SP3 NTFS non-system drive with 18GB free.
I dare not try to replicate this. As such, I cannot firmly place the blame on
PHP.
I have peppered a PHP application with a call to a function which appends-only
to a logfile the parameters passed to it. Each pass of the application creates
many MB of content.
It is conceivable that I ran out of hard drive space.
When that which what I was working on seemed to be acting very weird, I
rebooted the computer only to see thousands of lines scroll by from Windows
repairing the file system.
I discovered logfile contents in many dozens of files. The timestamp and
filesize of the damaged files were not changed. Only the contents replaced with
slices of the logfile.
Again, I'm not going to try to 'intentionally' replicate this, so I ask:
Has PHP's interface with the NTFS file sub-system ever been reported to
splatter a file across the contents of a drive?

Is the PHP-interpreter even possible to create something like this? As far
as I know PHP utilizes the common OS-syscalls to interact with the
filesystem, so it doesn't interact with the harddrive directly, but online
with the FS-driver. Did you shutdown the system cleanly, when you
recognized this behaviour? If not, it would explain, that the windows
assumes the filesystem must be repaired. I can imagine, that this "repair
process" associated the broken data with the wrong file-entries in the
fs-table, which could be an explanation for the behaviour you described.

Sebastian

Not to my knowledge. It actually sounds to me like a code issue.
Are you using file_put_contents() with the parameters in reverse
order, by chance?
If you can show the write portion of the code in your iteration,
as well as a sample of the naming convention, it may offer more clues.
In any case, either disk space or inode exhaustion is likely the
reason things borked-up for you.

$dbgMsg = "a diagnostic string maybe 5K in length";
$dbg_fp = fopen(ROOT_DIR.DS."dbg_log.txt", "a"); // Derives a full path
fwrite($dbg_fp, $dbgMsg);
fclose($dbg_fp);

Yes, a clean reboot. Not a reset-switch restart, nor a power-cycle restart.

This is the most suspicious looking thing.

Ya think?
I'm still trying to figure out what the OP wants us to do? Has he tried
anything?
From the sounds of it ( I didn't bother to un-zip his file) it appears
that he just wants to create a model template and fill in the center
(the 'article'?) appropriately depending upon the user's request. Post
the texts to a db, simplify his web design and add an identifying id
value to each link. Voila?
