display data with ajax or what?

[chunk]

i have a script which asks for a URL and when submitted it executes for 10 to 30 minutes. And save the data into .txt file also echo the data on web page

But the result is displayed when execution of the script is finished.

I want to know how can i get data displayed line by line whenever there is new echo in the script result

How are you doing it now? Also, do you have a server-side script scraping the pages or are you expecting your ajax call to do it? If you're using ajax to call another server, you're probably going to run into CORS issues.

I suspect the call currently isn't AJAX and is just simply PHP running....
switching it to an AJAX call though is likely going to be a major undertaking, and going to require some fundamental changes in the architecture which will affect the processing process.

You'd have a basic page that's going to display to the user and make the initial AJAX call... that AJAX call then invokes a web service... but it's still going to pause and wait for that service to finish before the AJAX call will return... so if the process still takes 20 minutes, it will wait 20 minutes before it can return and update the display.

So what you'll need to do is some how cache the results from the process, then make multiple AJAX calls to get the cached results and displaying that until there are no more results to get. Now how to do that... shrug... don't know... depends on what you're doing and how you're doing it. It might mean the status is written to a database and you read the results from there, or it might mean something completely different.

Bottom line, you'll need two methods to invoke... the first kicks off the process in the first place... the second would be to get the results.
