Question

I tried execute this code and I have done something wrong because it's always redirecting me to google:

    <?php

$email = $_POST['email'];
$after_email = explode('@', $email);
$part = $part[1];
if($part == 'aol.com') {
        header("Location: http://aol.com");
} else if($part == 'yahoo.com') {
        header("Location: http://yahoo.com");
} else {
        header("Location: http://google.com");
}
?>

this is my html form

<form action="snd.php">
email: <input type="text" id="email" name="email"><br>
<input type="submit" value="Submit">
</form> 

Answer 1

You called the explode() function on $email . This implies that $after_email is now an array. Your mistake was that you were accessing the wrong array variable.

Change this line:

$part = $part[1];

to:

$part = $after_email[1];

EDIT

Change this line in your form too:

<form action="snd.php">

to:

<form action="snd.php" method="post">

You also didn't specify the form method. By default, this is set to $_GET . But in your php script, you were calling the $_POST superglobal. Change the method to post and you are good to go.
