#6736 — problem in creating Zip file

Hi All
i m trying to create a Zip file of 1 folder which contains 2 folders and 33 files but the resulted zip file only contains 21 file and 1 folder.And when i open the files of zip folder it says files r corrupted.

Here is my code:
Plz help me to find out what is wrong there...

<?php

include("variable.php");

ini_set("max_execution_time", 18000);


// create object

$zip = new ZipArchive();

// open archive

if ($zip->open($outputfoldername . ".zip", ZIPARCHIVE::CREATE) !== TRUE) {
die ("Could not open archive");
}

// initialize an iterator
// pass it the directory to be processed

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($outputfoldername . "/"));

// iterate over the directory
// add each file found to the archive

foreach ($iterator as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}

// close and save archive

$zip->close();
echo "Archive created successfully.";
?>

Thanks
Regards Supriya

Had you considered that this may not be enough time?

I suppose 5 h should be pretty much enough for creating a ZIP file. But
indeed changing the max_execution_time might fail (e.g. when PHP runs in
safe mode). However, if the script outputs "Archive created
successfully.", the execution time can't be the problem.

Are you sure you CAN change the max execution time?  Many shared hosting 
environments don't allow it.

My mistake -- I thought it specified milliseconds, not seconds. I stand corrected.

try with max_execution_time with some lower value, 5 Hr is too much.

This will not help you, and as Jerry pointed out you may not be allowed to 
change the value.

Sure, the issue may be that the execution of the script needs more time, but 
you totally have forgot that there is a timeout in your browser, and when your 
browser times out, then the script will stop running on the server too and you 
end up with an unfinished job.

if you make some output here, then you will extend the life for your 
connection, unless one iteration takes too long time.

If you can, make a cron job of this instead (not many web hotels does offer 
customers to run cron jobs), the job reads from a database table which jobs it 
has to do, it takes the oldest one in the list each time it's run (set it to 
run every 5 or 10 minutes) and marks it to be worked on, so that no other 
instance will try to do the same time if it takes longer than the time you set 
between two jobs, and when the process is finished, mark the job as finished 
(this gives you the possibility to check for jobs which fails, specially if 
you also set the time when the job changed state).

Then in the web ui you just have a way to put jobs into the queue.

You get a lot more stable system this way.

Is the problem solved?

It could be an access restriction problem, be aware that your script runs with the
web server account.
