An explanation of the simple implementation method of php nginx real-time output

This article introduces you to the simple implementation method of php nginx real-time output through example code. It is very good and has reference value. Friends who need it can refer to it

The method to enable real-time output in PHP is ob_implicit_flush() ,

But it doesn’t work in most cases,

Because most of the output_buffering output buffering in the php.ini configuration is On,

and zlib.output_compression It is also often turned on.

In addition to the PHP layer, Nginx's buffering setting proxy_buffering and compression gzip are also mostly turned on.

I am afraid no one will make this choice to modify the website configuration of the entire server to meet the needs of one or two pages.

Here is a simple method recommended:

set_time_limit(0);
ob_end_clean();
ob_implicit_flush();
header('X-Accel-Buffering: no'); // 关键是加了这一行。
echo '现在是：'.date('H:i:s').'
';
sleep(5);
echo '五秒后：'.date('H:i:s');
