[RESOLVED] Browser not responding

motleydata

I'm new to php. I installed the php5, apache & mysql following the instructions from (http://www.webdevelopersnotes.com/how-do-i/install-PHP-windows-7.php). All th three installed successfully. The phpinfo() test performed well, but the problem I'm now facing is that the browser (Mozilla & IE) are reading the scripts but only the html part and leaving the php part without any output.
e.g:

<html>
<head>
<title> My first PHP program </title>
</head>
<body>
<?php
$a=5;	//global scope

function myTest()
{
echo $a;	//local scope won't print local variable
}

myTest();
?>

</body>
</html>

this script is read only as

<html>
<head>
<title> My first PHP program </title>
</head>
<body>

</body>
</html>

by both the browsers. Please help me run it.

did you save your file with the extension '.php' ?

also, you have a scope issues - 2 options:

$a = 5;	//global scope

function myTest($a)
{
echo $a;	//local scope won't print local variable
}

myTest($a);


//####################
// OR
//####################

$a = 5;	//global scope

function myTest()
{
global $a;
echo $a;	//local scope won't print local variable
}

myTest();

The browsers have nothing to do with "reading" scripts (or, more aptly, directing the appropriate requests to the PHP interpreter for the parsing/execution of any PHP code contained within a file).

Second, this:

<?php
$a=5;	//global scope

function myTest()
{
echo $a;	//local scope won't print local variable
}

myTest();
?>

will never output anything (except a PHP error message if you've got display_errors set to On and error_reporting set to report notices). As such, I'd say your example output matches the code you've supplied, so I'm not sure what the problem is... ?

In fact even the comment on the only line of php that would output something says that it won't print.

i have surely save it with .php and all files format.
the actual problem is that the script is not even shown in the source code by the browser

if it is not the browser problem, please let me know, what sort of problem is it?

It's not supposed to be shown there. If it is shown there, that means you've got a bigger problem since the PHP code was never executed in the first place. Otherwise, you'd be able to view the contents of any PHP script just by looking at the source of the displayed page in your browser. This would be a huge security risk.

(And if you're still not convinced that PHP code should never be able to be viewed from the browser, can you please view the source code of this page - e.g. the /board/showthread.php script - and show us all of the vBulletin PHP source code?)

It's a variable scope problem. Did you try reading the code comments in the code itself? They already explain (as Derokorian points out) that nothing will be echo'd, since there is no such variable called $a inside of that function.

EDIT: For more information about variable scoping, see the manual page: [man]variables.scope[/man].
