PHP uses cached instant output (output buffering) method _php Tips

PHP uses the method of caching the Instant output content (output buffering). Share to everyone for your reference. Specifically as follows:

$buffer = Ini_get (' output_buffering ');
Echo str_repeat (", $buffer + 1); Prevent browser Cache
Ob_end_flush ();//close cache for
($i =1 $i <=10; $i + +) {
  echo '. $i. ' Secondary output. '. ' <br/>\n ";
  Flush (); Flush cache (sent directly to browser) sleep
  (1);
}
echo ' Output complete! ';

The operation effect is as follows:

1th time output.
2nd time output.
3rd time output.
4th time output.
5th time output.
6th time output.
7th time output.
8th time output.
9th time output.
10th time output.
Output Complete!
