how do you get a php page to refresh or reload?
start right from the top again?

thanks in advance from sunny clearwater fl.

or without url

<META HTTP-EQUIV=Refresh CONTENT="3">

I dont like every time the page refresh. I want the page will be reloaded only once. can u help me to do that?

try this

header("Cache-Control: no-cache");

everytime the page is requested, a fresh copy is loaded. Is this what u r lookin for?

I am using php to get an image from database. when I get an image, the image will be shown after hitting the refresh button. pls help me to solve this

That must be because ur browser has a cache copy of the page...
browsers use this mechanism to enhance the surfing speed...
add this on top of ur page-

header(“Pragma: no-cache”);
header(“cache-Control: no-cache, must-revalidate”); // HTTP/1.1
header(“Expires: Mon, 26 Jul 1997 05:00:00 GMT”); // Date in the past

This will instruct browser not to maintain the cache copy of this specific page.. and hopefully u wont need to hit refresh to display ur image...
Cheers!!

its getting displayed in browser !!! Are you sure u placed these lines inside <?php tag??
Why dont u post up the code u r using and i shall suggest what modifications are required..

Have messed this up b4
If the nocache code is getting displayed in the browser in the output window
Assuming the page displayed is "page.php"
page.php includes the line <img src="getImageFromDatabase.php" alt='database blob image'> or something similar
The nocache code previously listed should be inserted in the <head> of "page.php" not "getImageFromDatabase.php" else that code is output to the browser as well as (or instead of) the image
the nocache code should work

hey almostbob,
correct me if m wrong but the header function is supposed to execute before displaying any output in the browser isnt it? then how are u supposed to place it inside head tag.
I believe it must go on the top of page which is used to display the image ie which outputs html for image display... watsay?
what you are trying to tell is the use of meta tag inside head which is also an option but doesnt works with IE. so the best way is to use http headers...

for me it is 3am
corrected text should read
The nocache code previously listed should be inserted in "page.php" not "getImageFromDatabase.php" else that code is output to the browser

I want to upload audio and video into the database.. Is it possible? If possible, then tell me how to do that?

To ensure an image is reloaded, send a unique URL.

eg:

<img src="image.php?random-number123" />

Where random_number123 can be generated by:

<?php

$random = microtime(true);

// eg

echo '<img src="image.php?'.$random.'" />';

?>

just use: <?php header("Location: #"); ?>

for example:

<?php

if (true) {

header("Location: #");

} else {
// nothing happens
}

?>

or, make a text link:

<a href="#">click this link</a>

"#" is often used to redirect people to the top of a page, but it will actually refresh the page as wel.

Greetings,

$_SESSION=true;
header ("Location: yourpage.domain");

Hie guyz! Have you tried

header( 'refresh: 2; url=/location/' );

where

refresh - tells the page to refresh
,
2 - tells the page to refresh in 2sec
and
url=/location/ - is the location of the page being refreshed.

U will notice that itz the same as redirecting but just to the same page.


For redirecting:

header( 'url=/location/' );

I dont like every time the page refresh. I want the page will be reloaded only once. can u help me to do that?

I use to use the php header function to refresh pages, but most of the times received
error messages.
So ever since, i'm using the next command:

<?php
// Refresh page
echo '<script> window.location=" '.$_SERVER['PHP_SELF'].' "; </script>';

?>

If you meant to refresh the page once actions have been done (ie, the php page received instructions through URL/POST, then performed some changes such as table refresh/db content changes) and you wish to display the new status then you can use the php 'header' instruction (w/ full URL to the php page) to call the same page. Let's say your php code is in 'myphp.php', your domain is 'my.domain.site' and your php file is located at the 'cgi-bin' directory (or as configured in your web server), then the instruction will be as such:
header("location://my.domain.site/cgi-bin/myphp.php")
Make sure to 'unset' any GET/POST values as needed prior to refresh the page.

on top of your code:

ob_start();
$url = "location_of_file.php";
header ("Location : $url");
