PHP refresh window? equivalent to F5 page reload?

问题

Is there anything in PHP that is the equivalent of manually pressing the F5 page reload button? My php script is in a frame and isn't the parent script but it needs to refresh the entire page and not just it's frame.

回答1:

With PHP you just can handle server-side stuff. What you can do is print this in your iframe:

parent.window.location.reload();

回答2:

Actually it is possible:

Header('Location: '.$_SERVER['PHP_SELF']);
Exit(); //optional

And it will reload the same page.

回答3:

If you have any text before a

header('Location: http://www.example.com/youformhere.php');

you'll have issues, because that must be sent before any other text is sent to the page.

Try using this code instead

<?php 
$page = $_SERVER['PHP_SELF'];
echo '<meta http-equiv="Refresh" content="0;' . $page . '">';
?>

Just remember, this code will create and infinite loop, so you'll probably need to make some conditional changes to it.

PHP cannot force the client to do anything. It cannot refresh the page, let alone refresh the parent of a frame.

EDIT: You can of course, make PHP write JavaScript, but this is not PHP doing, it's actually JavaScript, and it will fail if JavaScript is disabled.

<?php
    echo '<script>parent.window.location.reload(true);</script>';
?>

回答5:

<?php 
echo "<script>window.opener.location.reload();</script>";
echo "<script>window.close();</script>";
?>

回答6:

with php you can use two redirections. It works same as refresh in some issues.

you can use a page redirect.php and post your last url to it by GET method (for example). then in redirect.php you can change header to location you`ve sent to it by GET method.

like this: your page:

<?php
header("location:redirec.php?ref=".$your_url);
?>

redirect.php:

<?php
$ref_url=$_GET["ref"];
header("location:redirec.php?ref=".$ref_url);
?>

that worked for me good.

回答7:

Use JavaScript for this. You can do:

echo '
<script type="text/javascript">
   parent.window.location.reload(true);
</script>
';

In PHP and it will refresh the parent's frame page.

回答8:

guess you could echo the meta tag to do the refresh in regular intervals ... like

<meta http-equiv="refresh" content="600" url="your-url-here">

回答9:

All you need to do to manually refresh a page is to provide a link pointing to the same page

Like this: Refresh the selection

回答10:

Adding following in the page header works for me:

<?php

if($i_wanna_reload_the_full_page_on_top == "yes")
{
$reloadneeded = "1";
}
else
{
$reloadneeded = "0";
}

if($reloadneeded > 0)
{
?>
<script type="text/javascript">
top.window.location='indexframes.php';
</script>
<?php
}else{}
?>
