php code not executing in /xampp/htdocs folder

[qmqmqm]

Hi

 

I am new to php and this forum.

I have this following piece of code in a php file, which I put inside the /xampp/htdocs folder.

 

session_start();
$ses_startvar = "started";
session_register("ses_startvar");

//code after the HTML form
if (isset($posted)) {
if (strlen($_COOKIE[phpSESSID]) == 32) {
echo "Session ID is being maintained in a cookie<br> and is " . $_COOKIE[phpSESSID];
} else {
echo "Session ID is being maintained in a querystring<br> and is " . $GLOBALS[phpSESSID];
}

 

The php file loads fine. But when I click on the button, it should show me the cookie id. However when I click on the button nothing is echoed.

 

Does anyone know why?

 

Thanks,

 

Tom

change:

$_COOKIE[phpSESSID];

 

to:

$_COOKIE['PHPSESSID'];

Thank you The Little Guy. Unfortunately that does not solve the problem.

 

In fact I am having some trouble with other php code as well, such as:

 

$my_var = $form_var;

echo "The value of \$my_var is $my_var <br>";

if (is_numeric($my_var)) {

$my_var = $my_var * 1;

}

if ($my_var == "true" or $my_var == "false" or $my_var == "yes" or $my_var == "no") {

settype($my_var, "boolean");

}

echo "The data type of \$my_var is " . gettype($my_var);

 

Nothing would be echoed on the webpage when I click on the button.

 

Anybody knows why?

 

Thanks.

The code you posted relies on a feature (register_globals) that was turned off almost 7 years ago in php4.2 and has been removed in php6. You either need to fix the code or find more up to date code that does what you want.

I actually got these pieces of code from

http://www.vtc.com/products/PHP-Project-Solutions-tutorials.htm

 

which is published in 2004... Could there be other possibilities?

 

Thanks,

No mistake. The following problems exist in the code you posted -

 

session_register("ses_startvar") does not work. Code needs to use the correct $_SESSION variable.

 

$posted appears to be from a form field and does not work. Code needs to use the correct $_POST or $_GET variable.

 

$_COOKIE[phpSESSID] is incorrect syntax. The correct syntax is $_COOKIE['PHPSESSID']. The first form does function but goes through a painfully slow defined constant search and error handling/recovery process before the actual array variable is referenced.

 

In the last code you posted $form_var appears from a form, like the $posted variable and has the same problem.
