PHP implements the principle of progress bar

The principle of PHP implementation of progress bar:

Template replacement, set a logo on the page, wheel your own page, without sending a request to the server , the server side obtains the progress, and then replaces the page identifier to achieve the progress bar effect.

Page code:

                  
  
0
 
{%a%}
  

Server code:

'; echo str_repeat(' ' ,2024); $url = '/t/test.php'; header("Location: " . $url.'&id='.$i); $read_url = realpath('.'.$url); $content = file_get_contents('D:/phpnow/htdocs11/design/t/test.php'); $rr = preg_replace('/{%(.*)%}/','{%'.$i.'%}',$content); file_put_contents('D:/phpnow/htdocs11/design/t/test.php',$rr); ob_flush(); flush(); sleep(1); } ?>
