serious problem need help.

[Bob Bedford]

Hi all,
I'm having troubles with my hosting and for a few reasons I can't change.

So here is my problem: I receive XML files with images included in the file.
I've to parse the file, save datas in a database and save images after
resizing them. The whole process takes sometimes more than 10 seconds (the
limit of the scripts) so I've errors.

It's there any way to have an other process that do the image processing
(like an automatic "post" wich send the images) ? How ? Exec isnt' allowed
on the server.

Please help....

then you should to set new time limit for script execution

Obviously you guess I can't do it !!! I can't modify anything in the server
settings.

Some hosts let you change the timeout using ini_set, does yours?

If not could you split the processing over two scripts?

In the first script parse the xml file, update database, copy the image
to a temporary file and use $_SESSION to store the temp filename. Then
redirect to the second script using header('Locatio n:') and let the 2nd
script finish off the resizing & database updates

This way you have a whole twenty seconds to play with.

he can't, thats it. Maybe he has a shared hosting service.
Bob, I heared of a method how the script calles itself if the execution-time
reaches a limit. Maybe that could be helpfull. I saw it in a script, but i
don't remember its name, it was about mysql, mysqldump or something like
that.

No, id doesn't allow using ini_set. (it would be too simple).

That's the way I'm looking for.

It's there any way in PHP to execute (without using location as it changes
page) a new page ? I don't have access to exec()...
My idea is to manage the recording in the database then every time I've new
images, send them to a new script. The main process will do easely in 10
seconds then every process will redim and save the images (time consuming)
and it may also do it in 10 seconds.

Problem: I don't know how to do so (launch an other script without exec)
passing the files (like a normal post or get will do).

Do you have access to CRON? If so, you could parse the xml upon
retrieval and store the paths to the images to be redimensioned in a
table queue. You could then have a cron script run once a minute or
(as often as necessary) to try and clear out the queue.

Another alternative to CRON, would be to create a script that checks if
anything needs to be done every time a page is clicked upon. It can be
as simple as adding a function call or include() to the pages you want
to act as the trigger. It's more of an advantage when you get heavier
traffic on a website, but it's a possibility. I think the best place to
add a trigger, would be to the footer (if you use one) which would be
appended to every page, and trigger last thing, so it wouldn't
interfere with the page generation for the user.

You can curl or sockets to post data to another script

http://uk.php.net/manual/en/ref.curl.php

http://uk.php.net/manual/en/function.fsockopen.php.

The 1st script may timeout waiting for the response, I dont think this
will affect the execution of the 2nd script, as long as the 2nd script
starts before the 1st timeouts. A best guess not a guarantee..

Bob,

You don't "launch another page with exec()". Rather, you redirect to
the new page with header('Locatio n: pagename').

Just be sure you don't create any output before this. And you can save
the data you're working on in the session (or pass it as GET parameters).

Yup, perhaps flush(), and maybe on more traffic (allthough, on more traffic
an other hoster might be more helpfull), create a possibility it's fired:

if(rand(0,99) == 1){
//run script
}

Thanks for your reply, I'll have a look at this solution.

I wanted to avoid to redirect as I've to pass by all records I've already
done every time I call the script again and this will be very long.

I've got an other answer it has been said to "refresh" the page. Will first
look at fsockopen then at this solution. Maybe I'll do both.

Thanks.
