refreshing browser window using PHP

[jcvertin]

I would like to refresh a web page everytime it is visited. when you go onto a link on the page and them go back to the main page, the main page doesn't refresh even though inforamation on the page has changed. Clicking the refresh button works, but I would like to code the page so that it refreshes itself automatically every time it is viewed.

This sounds like the browser is caching it and using the cache first, right? I suggest you have the link generated by php code with a random ID. Say the link is to main.php- have the <a> tag be:

<a href="main.php?<?PHP echo rand(0,1000); ?>">Home</a>

... so the main.php script would be passed an pseudo-random number every time, causing it to reload from the server every time (in most browsers).

or throw in a js reload thing ?

// at the head of the main.php file 
echo "<script>location=main.php</script>";

Um... wouldn't that make the page constantly reload? It seems like jcvertin wants it to reload every time the browser goes to the page, not constantly.

You could simply set it though so that on being triggered it sets a variable - eg $pagereloaded = 1

Use iisset to test for the variable and if it is found dont run the refresh script again.
