[RESOLVED] Echo not working.....

Zabuza

Ok, I am in the beginning stages of making a file explorer for one of my classes, and it seems like echo is not working. The code looks like this:

<html>
	<head>
		<title>Assignment 1 - File Explorer</title>
	</head>
	<body>
		Entering PHP<br>
		<?php
			echo "Path = ";
			if(!(isset($_GET["path"])))
				$path="C:\cs393\Web\Assignment1"
			else
				$path=$_GET["path"];
			echo $path;
			echo "\n<br>";
		?>
		Leaving PHP<br>
	</body>
</html>

And the page looks like this:

Entering PHP
Leaving PHP

Any ideas as to what is making echo not work?

Have you look at he source code of your (resulting) page inside your browser ?

Is it displaying something between "Entering PHP" and "Leaving PHP" ?
The PHP code actually ?

In what file (filename) do you save the whole code ?

For instance, let's say you save it in a "example.html" file. If "html" extension
is not associated with PHP engin inside Apache configuration, the PHP portion
will never be executed.

If that's the case, then try renaming your file to "example.php" and then call it.

you missed the ; at the end of this line

$path="C:\cs393\Web\Assignment1"

1) added the ; - Didn't change a thing
2) changed the extension to .php, but it didnt open in ie. It tried to download it.
3) source code is as follows:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD><TITLE>Assignment 1 - File Explorer</TITLE>
<META http-equiv=Content-Type content="text/html; charset=windows-1252">
<META content="MSHTML 6.00.2900.2802" name=GENERATOR></HEAD>
<BODY>Entering PHP<BR><?php
			echo 'Path = ';
			if(!(isset($_GET["path"])))
				$path='C:\cs393\Web\Assignment1';
			else
				$path=$_GET["path"];
			echo $path;
			echo '\n<br>';
		?>Leaving PHP<BR></BODY></HTML>

So the php is in the source, but it isnt executing......

Alright... now were getting somewhere. Php needs to be in files with the .php extension. When you say your trying to open it in ie, are you using an address like http://localhost/filename.php ? Do you have a webserver installed?

Php runs on the server, so you need on einstalled and running for php to be interpreted.

Whoops, I kept opening it from explorer without going through the localhost.....

Ok, one more question:
Is there any way to have html code around the php script? I have it in the middle of the html, but it just ignores the html because it is a .php link. Would I have to have the html code call the php source?

Figured it out. Thanks a bunch for all of your help.

If anyone ever has a similar problem, here is the source for what I changed the code to:

<?php
	echo "<html><head><title>Assignment1 - File Explorer</title></head><body>Entering PHP\n<br>";
	echo "Path = ";
	if(!(isset($_GET["path"])))
		$path='C:\cs393\Web\Assignment1';
	else
		$path=$_GET["path"];
	echo $path;
	echo "\n<br>Exiting PHP\n<br></body></html>";
?>
