GET URL parameter in PHP

(Mind you I am fairly new to PHP and still learning) I have form:

<form name="checkingEmail">
        E-Mail: <input type="text" name="email1" />
        <br />
        Retype E-Mail: <input type="text" name="email2" />
        <br />
        <input type="button" value="Submit" onClick="checkEmail()">
    </form>

and I want to take the values from the User Input and do a simple If...Else statement after they hit "Submit"

PHP:

<?php
$email1 = blah //Value from email1 input form here;
$email2 = blah //Value from email2 input form here;
function checkEmail()
{
global $email1, $email2;
if($email1==$email2)
{
//Some Code Here
}
else
{
echo "Make sure your E-Mail addresses match";
}
}
?>

Answer 1

You should be using the GET or POST variable on your form .. so include the method attribute in your form element:

<form method="get">

And then use GET or POST for a more secure approach ... the form input isn't shown in the URL when using the POST method.

You can use either like:

$email1 = $_POST['email1'];
$email2 = $_POST['email2'];
