This article mainly introduces the invalid php flush and the real-time output method of php under IIS7. Friends who need it can refer to it

In a relatively time-consuming operation, I want to record the operation in real time on the browser When displayed, flush() is used to send the content in the buffer to the browser. But in iis7, PHP configured in fastcgi mode cannot be implemented, and the results are always displayed together.

for ($i=10; $i>0; $i--) { echo $i.'
'; @ob_flush(); flush(); sleep(1); }
Copy after login

The above code cannot gradually display the results under the default settings of IIS. The solution is as follows:

Open the file C:\Windows\System32\inetsrv\config\applicationHost.config. Note that if your system is 64-bit, this file must be opened with 64-bit editing software. 32-bit When opening the software, it will prompt that the file does not exist. Just use the notepad that comes with the system to open it. Find the following paragraph and add the red code, that is, add responseBufferLimit="0" to the php handler.

Copy codeThe code is as follows:

 
Copy after login

Now you can try it. If it still doesn’t work, set output_buffering = Off in php.ini.

The last point is very important. In different browsers, there are different results. There should be no problem in IE. If you use Chrome, each echo content must contain html, otherwise it will not work. Also, if the echo content is too short, this effect cannot be achieved. You can output it before the code. A space, such as: echo str_pad(' ', 1050); Chrome seems to have to output more than 1000 characters first to have this effect. If it doesn't work, try more.

Summary: The above is the entire content of this article, I hope it will be helpful to everyone's study.
