Question

I have to process more images with big amount, (10 mb/image)

How do I determine the execution time to process all of the images in queue?

• Determine the time base from the data that we have.

• Set the time limit.

• Run process.

And what do the execution time depend on? (Server, internet speed, type of data…?)

@All:
i have changed my way to do my issue, send 1reqeust/1image,

so with 40 images, we will be have 40 request. no need to care about excution time 😀

Thanks

You can test your setup with the code

// first image
$start = time();
// ... work on image ...
$elapsed = time() - $start;

if (ini_get('max_execution_time') > $elapsed * $imageCount)
    trigger_warning("may be not able to finish in time", E_USER_WARNING);

Please note two things: in the CLI-version of PHP, the max_execution_time is hardcoded to 0 / inifinity (according to this comment). Also, you may reset the timer by calling set_time_limit() again like so:

foreach ($imagelist as $image) {
    // ... do image work ....

    // reset timer to 30
    set_time_limit(30);
}

That way, you can let your script run forever or at least until you’re finished with your image processing. You must enable the appropriate overwrite rules in the apache-configuration to allow this via AllowOverride All
