system() and exec() hangs up php

[krisen]

Hi.

I use system() with imagemagick (convert) to resize images.

If i loop through some images and first run the system("convert ....") to resize, then a query to insert the image in the database,

Something like:

for (every image..)
{
system("convert ...");
mysql_query("INSERT ...");
}

The problem is that NO php-page can be accessed while this is going on. Php hangs up completely until all images are done.

If the current page hangs up, thats OK, thats actually needed since I need the correct file to be ready before inserting it in the database. But I still want users to be able to browse other parts of the site while images are being resized.

How could I solve this? Any other methods than imagemagick?

Thanks.

If you're using sessions then the session data will be locked while the page is processing. Try calling session_write_close just before starting the time consuming stuff. You can start the session again afterwards if need be.
