PHP uses the method of caching real-time output content (output buffering). Share it with everyone for your reference. The details are as follows:

$buffer = ini_get('output_buffering');
echo str_repeat(' ',$buffer+1); //防止浏览器缓存
ob_end_flush(); //关闭缓存
for( $i=1; $i<=10; $i++ ){
  echo '第 '.$i.' 次输出.'."<br />\n";
  flush(); //刷新缓存(直接发送到浏览器)
  sleep(1);
}
echo '输出完毕!';

Copy after login

The operation effect is as follows:

1st output.
2nd output.
The 3rd output.
The 4th output.
The 5th output.
The 6th output.
The 7th output.
The 8th output.
9th output.
The 10th output.
Output completed!

I hope this article will be helpful to everyone’s PHP programming design.
