Falling distance code help

Hi there, I need some help figuring out what is wrong with my code. See below.

<form action="assgn2.php" method="POST">
Time object has fallen: <input type="text" name="time" />
<input type="submit" value="Submit" />
</form>

<?php

$time; //= $_POST['time'];
$distanceFallen = (1/2) 9.81 pow($time, 2);
echo $distanceFallen;

After I enter the time and click submit, it will say "Internet Explorer cannot display the web page".

Any help would be greatly appreciated. 😃

$time is undefined. Why aren't you using the $_POST array, since that's where the data will be?

Sorry take out // in front of $_POST

And what about the extra semicolon? Any chance you can just show us the code that you're actually using?

Also, are there any entries in your webserver's error log and/or PHP's error log?

<form action="assgn2.php" method="POST">
Time object has fallen: <input type="text" name="time" />
<input type="submit" value="Submit" />

</form>

<?php

$time = $_POST['time'];
$distanceFallen = (1/2) 9.81 pow($time, 2);
echo $distanceFallen;

Code looks fine to me, which makes this question:

all the more relevant.

Speaking of error logging, if you do a [man]phpinfo/man, what are the values for display_errors and error_reporting?

Have you tried this in any other browsers?
Is this online, or on your local machine?

When I checked error logs in XAMPP under Apache, says Session Cache is not configured....?
