Forms - or doing something a little more useful with PHP

You have seen so far a lot about the structure of PHP but with the use of forms, PHP can allow you to process your users requirements what ever they might be. Below is a standard form which in the action attribute of the form tag has the name of the file that the form currently resides in.
<form action="login.php" method="post">
 <label for="username">Username</label> <input type="text" name="username" />
 <label for="password">Password</label> <input type="password" name="password" />
 <br/><input type="submit" value="Login"/>
At the top of the file login.php should go the following:
if (!empty($_POST))
 //if the code reaches here it means the form has been posted!
 echo $_POST["username"];
 echo $_POST["password"];

Notice that PHP code needs to go within PHP tags. This above code snippet extracts the form values from the post array.

The following line of code:
if (!empty($_POST))
Ensures that there are some post values otherwise it doens't try to read the post array. This is the post array $_POST which contains the form values and this is the name one of the form element that was posted in the above form password.

Instead of using isset as every tutorial are teaching to beginners , you are giving !empty() to users so i am voting this as excellent
