The test code is as follows:

 abc___'.$i;ob_flush();flush();sleep(1);}ob_end_flush();?> 

In theory, it should be one second, right? However, the test result is only 5 seconds later.
I checked on the Internet the following example: "Some web server programs, especially the web server programs under Win32, will still cache the script output before sending the results to the browser, until the program ends. "I am a 64-bit windows local xampp integrated environment.

This method of occupying user bandwidth without reason is boring.
The effect of delayed output should be implemented using js in the browser

Your code will never see the expected results in IE, because IE needs to wait until the buffer is full to explain the received data.

Yes, No. I don't know much about this function. I am using chrome for testing.
In fact, I want to achieve this: for example, I write a script to batch process some files.
But that process may be very long. if it is used by others, no one else knows whether it is being executed or stuck.
Therefore, if the execution of each loop is successful, an xxxx statement is output successfully;

The most similar is the display of data tables created when we install open source software.
However, what I write is displayed only after all the data tables are created.

My idea is not "latency", but "instant" display of my completed operations. I don't know what tips the moderator has.

Same question! I also have a program that runs for several hours. I can only check the data in the database to check whether the program runs normally.
My current practice is only for simple monitoring. For example, add a memcache write operation to the program and write a page to read the data.

I'm back. try again.

 ';ob_flush();flush(); sleep(1);}?>

These two days, this problem is quite a lot.
This method can be tested in various browsers, but some children's shoes said that this method can be used to write garbage into the cache area. you can try PHP to throw an exception and try again when you are free to study it.

I tried it and it was OK. Where is the secret?

Is it because of this? Echo str_pad (', 4096 );
The second setting time limit can be omitted. this program will certainly not run for more than 30 seconds.
Throw an exception. try-catch can also be used in this way. now, let me think about it! You are a good person!

Well, I started to consider using php_cli for this program. because of the many program steps, I thought it was unfriendly, but I still chose the page. However, the running time was too long and it became cumbersome to open the page, use cli. come on.

Today, I tried to use chrome for testing again, or wait until the computation is complete and output the data at one time.
