我应该在调用Location:标头后调用exit()吗? [英] php - Should I call exit() after calling Location: header?

问题描述

调用重定向函数头后，是否应该调用exit?

After calling the redirect function header, should I call exit or not?

<?php // fileA
$urlFailToGoTo = '/formerror.php';

if (sth)
{
   header(sprintf("Location: %s", $urlFailToGoTo));
   exit(); //should I call exit() here? or return?
}

?>

谢谢

推荐答案

您绝对应该.否则脚本执行不会终止.单独设置另一个标头不足以重定向.

You definitely should. Otherwise the script execution is not terminated. Setting another header alone is not enough to redirect.
