php redirect fails and does not do anything

i have just a simple php file with this line of code.

  <?php header("Locati开发者_JAVA技巧on: MyBooks.php", true); exit();?>

Form 1 submits form to this simple php file and this file supposed to redirects to MyBooks.php within the same directory.

i just do not get it, why it does not redirects ?

there's no errors reported.

Seems like an issue in server you are running: http://social.msdn.microsoft.com/Forums/expression/en-US/db37d2ea-65ef-40ad-8a25-62a846a5d00d/php-headers-and-redirect

So you have to manually specify response code to 302 before sending location header:

header('HTTP/1.0 302 Found');
header('Location: http://localhost/MyBooks.php');
exit;

And remember to use absolute URL in Location.

It's possible that you have already sent some output through your script (which could be just whitespace), in which case you cannot send headers anymore.

Test it with this code:

if (headers_sent()) {
    die("Error: headers already sent!");
}
else {
    header("Location: MyBooks.php", true);
    exit();
}

If this prints an error, then you need to make sure that there's no output at all going out before the header call. Check that:

• You do not echo anything at all (or otherwise output any HTML) before the header call
• There is absolutely no whitespace before the <?php start tag or the ?> end tag (if present) in your PHP scripts

Update: How to check HTTP headers using Chrome

1. Select the Network tab
2. Choose Documents from the menu just above the console to narrow down the list on the right
3. Choose the only resource that the filter matches from the list on the right (http://localhost/ here)
4. Click the Headers tab

The only way that i could do that was :

$url = "http://www.google.com";
echo "<script>window.open('".$url."','_self');</script>";

You can also combine the two header calls into:

header('Location: http://localhost/MyBooks.php', true, 302);
exit;

So you won't need to remember the format/description of the HTTP Status code. The signature of the header function is

void header ( string $string [, bool $replace = true [, int $http_response_code ]] )

I thought no problem in this code check the execution come this line or not,

try without boolean

<?php header("Location: MyBooks.php); exit();?> 

I had this problem and it was due to multiple locations being set in the header before the script ended.

<?php
    // WARNING: BAD CODE

    if($thisShouldBeTrue) {
        header('Location: http://www.example.com');
    }

    if($weShouldNeverGetHere) {
        header('Location: http://www.otherexample.com');
    }
?>

I thought that php would redirect immediately at the first header and never get to the second if block. I was wrong. Always die() or exit after a redirect if your intent is to go there immediately.

<?php
    // CORRECT

    if($thisMightBeTrue) {
        header('Location: http://www.example.com');
        die();
    }

    if($orThisMightBeTrue) {
        header('Location: http://www.otherexample.com');
        die();
    }
?>
