Redirect to specified URL on PHP script completion?
提问by JoshFinnie
How can I get a PHP function go to a specific website when it is done running?
运行完成后，如何让 PHP 函数转到特定网站？
For example:
例如：
<?php
//SOMETHING DONE
GOTO(http://example.com/thankyou.php);
?>
I would really like the following...
我真的很喜欢以下...
<?php
//SOMETHING DONE
GOTO($url);
?>
I want to do something like this:
我想做这样的事情：
<?php
//SOMETHING DONE THAT SETS $url
header('Location: $url');
?>

<?
ob_start(); // ensures anything dumped out will be caught
// do stuff here
$url = 'http://example.com/thankyou.php'; // this can be set based on whatever
// clear out the output buffer
while (ob_get_status())
{
ob_end_clean();
}
// no redirect
header( "Location: $url" );
?>

You could always just use the tag to refresh the page - or maybe just drop the necessary javascript into the page at the end that would cause the page to redirect. You could even throw that in an onload function, so once its finished, the page is redirected
您总是可以使用标记来刷新页面 - 或者可能只是在最后将必要的 javascript 放入页面中，这会导致页面重定向。你甚至可以把它放在一个 onload 函数中，所以一旦它完成，页面就会被重定向
<?php
echo $htmlHeader;
while($stuff){
echo $stuff;
}
echo "<script>window.location = 'http://www.yourdomain.com'</script>";
?>

If "SOMETHING DONE" doesn't invovle any output via echo/print/etc, then:
如果“已完成”没有通过 echo/print/etc 调用任何输出，则：
<?php
// SOMETHING DONE
header('Location: http://stackoverflow.com');
?>
回答by FryGuy
Note that this will not work:
请注意，这将不起作用：
header('Location: $url');
You need to do this (for variable expansion):
您需要这样做（用于变量扩展）：
header("Location: $url");

don't forget to put a 'die' after your call to make the redirect happen before the rest of the code on the page is run threw. a. if you have header functions further down the page they will override the ones further up the code.
不要忘记在调用后放置一个“死”，以便在页面上的其余代码运行抛出之前进行重定向。一种。如果您在页面下方有标题功能，它们将覆盖代码上方的标题功能。
b: im assuming you dont want the rest of the code on the page to be run and that why your putting this redirect in in the first place [maybe].
b：我假设您不希望页面上的其余代码运行，这就是为什么您首先将此重定向放在首位 [也许]。
example:
例子：
<?php
// do something here
header("Location: http://example.com/thankyou.php");
die();
//code down here now wont get run
?>

Here's a solution to the "headers were already sent" problem. Assume you are validating and emailing a form. Make sure the php code is the first thing on your page... before any of the doctype and head tags and all that jazz. Then, when the POST arrives back at the page the php code will come first and not encounter the headers already sent problem.
这是“标头已发送”问题的解决方案。假设您正在验证并通过电子邮件发送表单。确保 php 代码是您页面上的第一件事……在任何 doctype 和 head 标签以及所有爵士乐之前。然后，当 POST 返回页面时，php 代码将首先出现并且不会遇到已发送的标头问题。
