PHP nginx real-time output implementation method sharing

This article mainly 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. I hope it can help everyone.

The method to enable real-time output in PHP is ob_implicit_flush(), but it does not work in most cases because most of the output_buffering output buffering in the php.ini configuration is On, as well as zlib. output_compression is often turned on. In addition to the PHP layer, Nginx's buffering setting proxy_buffering and compression gzip are also mostly turned on. I'm afraid no one would 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').'<br>';
sleep(5);
echo '五秒后：'.date('H:i:s');
