PHP script disappears after HTML

aescott

I have an unusual problem.

I've developed a website using a mixture of PHP, javascript and XHTML. The site works fine on my PC, using either Firefox or Internet Explorer.

I've sent the code to a colleague, but he can't get it to work, although he seems to have the same software and settings as me. When I look at the source code through his browser, the bulk of it is missing, as follows:

<?php
	session_start();
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
	<head>
		<title>ESRU Temperature Display Website: DTI Data</title>
		<link type = "text/css" rel = "stylesheet" href = "styles/styles.css" />
<SCRIPT language="javascript" type "text/javascript" >
<!--
	function reload_first(form)
	{
		//relaod the page using the data selected from the first drop-down box
		var site_val=form.site_sel.options[form.site_sel.options.selectedIndex].value;
		self.location='site_sel.php?site_sel='+site_val;
	}

function reload_second(form)
{
	//relaod the page using the data selected from the second drop-down box
	var site_val=form.site_sel.options[form.site_sel.options.selectedIndex].value;
	var sens_val=form.sens_sel.options[form.sens_sel.options.selectedIndex].value;
	self.location='site_sel.php?site_sel='+site_val+'&sens_sel='+sens_val;
}

function reload_third(form)
{
	//relaod the page using the data selected from the third drop-down box
	var site_val=form.site_sel.options[form.site_sel.options.selectedIndex].value;
	var sens_val=form.sens_sel.options[form.sens_sel.options.selectedIndex].value;
	var devs_val=form.devs_sel.options[form.devs_sel.options.selectedIndex].value;
	self.location='site_sel.php?site_sel='+site_val+'&sens_sel='+sens_val+
	'&devs_sel='+devs_val;
}

function reload_fourth(form)
{
	//relaod the page using the data selected from the third drop-down box
	var site_val=form.site_sel.options[form.site_sel.options.selectedIndex].value;
	var sens_val=form.sens_sel.options[form.sens_sel.options.selectedIndex].value;
	var devs_val=form.devs_sel.options[form.devs_sel.options.selectedIndex].value;
	var chan_val=form.chan_sel.options[form.chan_sel.options.selectedIndex].value;
	self.location='site_sel.php?site_sel='+site_val+'&sens_sel='+sens_val+
	'&devs_sel='+devs_val+'&chan_sel='+chan_val;
}

function reload()
{
	self.location = 'site_sel.php';
}

function redirect()
{
	self.location = 'date_sel.php';
}
-->
	</script>
</head>

<?php_track_vars?>

<body>
<table class = "t1">
	<tr><td><a href = "http://www.esru.strath.ac.uk/"><img src = "Images/esru.png" alt = "ESRU logo"/></a></td>
	<td><p class = "header1">ESRU Temperature Graphing Utility:<br /> DTI Data</p></td>
	<td><a href = "http://www.strath.ac.uk/"><img src = "Images/strath.png" alt = "University of Strathclyde logo"/></a></td></tr>
</table>

The first bit all appears OK, but the main part of the code (see below) doesn't appear when I view the source through the browser (although I can verify that it's there with a text editor)

	<?php
	$existing_array = $_SESSION["arrval"];
	if($existing_array != null)
		$existing_array = unserialize($existing_array);
.....//goes on for many more lines

Can anyone shed any light on this?

You shouldn't be able to see any PHP code from the browser, all the code is parsed by the server and only the results will show when you view source in the browser.

That's true, which means that your colleague most likely didn't install the web server on their computer correctly, or the web server isn't configured properly, because PHP code is designed to be parsed on the server, therefore only HTML it served to you from the server.
