In php, after a header() jumps to another page, exit() must be added
<?php
//如果答完题就跳转到结果页面
if($n==4){
header("Location:result/index.htm");
exit();
}
$n = $n+1;
file_put_contents($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR."n.txt","00000000000000",LOCK_EX);
?>If the header() jumps away without adding exit();, the following write statement will be executed (despite the jump to Another page, but the subsequent statements will still be executed).
