Detailed explanation of the steps to achieve real-time output with php nginx
This time I will bring you a detailed explanation of the steps for php nginx to implement real-time output. What are the precautions for php nginx to implement real-time output? The following is a practical case, let's take a look.
The method to enable real-time output in PHP isob_implicit_flush(),
but it doesn’t work in most cases, because of the php.ini configuration Most of the output_buffering output buffering is turned on. Also zlib.output_compression is often turned on.In addition to the PHP layer, there is also Nginx's buffering setting proxy_buffering, and compression gzip is 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').'<br>';
sleep(5);
echo '五秒后：'.date('H:i:s');Summary
