Implementation method of php nginx real-time output
This article explains how to implement php nginx real-time output.
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 It is turned on.
Also zlib.output_compression is often turned on.
In addition to the PHP layer, Nginx's buffer 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');
