All the commands that are between <? and ?> will always execute as long they are loaded from an php file.

For example, if you add:
Code: 
echo "hello world";

and load it in the browser, at the end of your file you'll have that text printed (Now, if the browser display it, is another issue)
But remember, to have php code executed, your html file needs to be renamed from myfile.html to myfile.php

no sir, i mean after the <html> to </html> tags was loaded, the php script will execute. the php script not execute if the html page is not complete to load.

in java script u can use setTimeout() function.
then i use the sleep() function in php but didnt work. the page of html will not appear until the sleep time will reach.
i want to appear the page of html. after the page containing of html will completed then the php script will execute!!

What you want is impossible. The browser will think the page is still loading until all PHP has finished executing. The best alternative would be to use a javascript onload function that sends a request to the server once the page has loaded. What exactly are you trying to achieve with this?

i finally solved it using javascript here is sample

<html>

<head>
<script type="text/javascript">

function delayer(){
document.write("<?php phponload();?>");
}

</script>
<title>Untitled 4</title>
</head>

<body onload="setTimeout('delayer()',15000);">





</body>
</html>



<?php

function phponload(){
echo "hello world";
}

?>
after the html page was loaded the php script will execute after 15 seconds.

PHP is a server-side language. This means that the server processes the page, executes the php then sends it to the browser. The browser will never see nor execute php code. What you are trying to achieve is not possible using php.

JavaScript, on the other hand, is a client-side language. This means that the browser processes the page, executes the JavaScript. The server will never execute javascript code.
