I don't know how to debug this problem... I'm trying to do a redirect with a header:
header('Refresh:5;Location:https://www.google.com/);
exit();
but I get the following error:
Failed to launch 'location:https://www.google.com/' because the scheme does not have a registered handler.
Now I understand that this is related to whether I have sent some output on the screen... but in my case I have verified that it was not with the following example:
ob_start();
$validate = ob_get_contents();
ob_end_clean();
var_dump(mb_strlen($validate));
the result is:
**0**
how do i know it might be related to other header use:
var_dump(headers_list());
the result is:
array(4) {
[0]=>
string(24) "X-Powered-By: PHP/7.4.28"
[1]=>
string(38) "Expires: Thu, 19 Nov 1981 08:52:00 GMT"
[2]=>
string(50) "Cache-Control: no-store, no-cache, must-revalidate"
[3]=>
string(16) "Pragma: no-cache"
}
Questions:
Is the error due to having established the session? Do I understand that the header or the list of the header is due to having established the session?
I don't see how to solve the problem... it's not 1 or 2 or 3 files, it's a lot of files before reaching the redirector?
NOTE: I'm trying to use mandatory header, it shouldn't use meta tag or javascript.
CodePudding user response：
This error is not related to header or sending headers or web browser.
Actually, the two questions that a php developer can ask you should be discarded since the problem is a bad documentation in php.
For redirect you must use url instead of Location:
header('Refresh:5;url:https://www.google.com/);
this is not properly documented on the PHP page, but can be found in a comment below.
