Buffered data is not sent to the upper layers unless the buffers are full or PHP code execution is finished. As soon as you ask the browser to fetch the web page, you will see that the browser is indicating that it has started to receive content. You can try different multipliers to get a more solid grip on these concepts. There are, however, some caveats that you should be aware of.

It will even work without the for loop. Ajax requests are a nice and elegant way of getting data without reloading the full page.

Your Answer

We associate a callback with an Ajax request and that callback gets executed once all content is received. This means that we cannot stream content in Ajax requests. Progress events are used to tell the user how much data we have uploaded, and we can also get downloaded data in chunks. An Ajax request is initiated to fetch data from response. Whenever a new chunk arrives, we output it in an alert. Now put the following code in response. This content gets sent to the upper layers with the flushes.

Now go ahead and click on Test Ajax Streaming.

When the entire Ajax request is successfully completed, you will see the complete output in the console. We have just implemented streaming in Ajax requests and we can easily update our interface accordingly, giving end-users an outstanding experience. Note: there are some browser incompatibilities. Test the above code in both Chrome and Firefox.

Firefox will behave exactly as demonstrated in terms of output, but Chrome will display an empty alert first, and then continue as expected. Keep this edge case in mind when implementing streaming!

Conclusion Streaming is an awesome way of sending content to the user in order to simulate speed. Since we have sent the status code in advance along with headers, cookies etc.

Sending small chunks of data is inefficient as networks prefer a small number of chunks with bigger responses instead of a high number of chunks with smaller responses. In order to send content in chunks, we have to choose the chunk size carefully.

The problem was that if we have say a doc file and if we link that file directly then some browser may attempt to download it, or some will just show it! So, what we will learn today is how to stream a file using PHP, instead of direct linking and force the browser to download it with a custom name defined by us!

Details about the conversion are stored in the debug log. According to the above information, we can easily see that the default size of the PHP buffer under most configurations is bytes 4KB which means PHP buffers can hold data up to 4KB.

Tag the conversion with a custom value. Can you try those classes: Thank you. Returns int - The number of credits.
