help with basic PHP assignment

I am applying for an internship and they gave me an assignment to complete. They know I have a background in C and have absolutely no experience with PHP. They want me to demonstrate the ability to find the answer to a problem not necessarily demonstrate my knowledge of coding. The following are the parameters of the assignment:

Create a form that gathers all the information and sends an email with all info upon submitting it.

Form Structure:

first_name, last_name, email and phone.

All fields should be required.

Validate the email.

Validate the phone structure.

This is a tremendous opportunity for me to learn and gain valuable experience. Any help is truly appreciated. Thanks.

 

<form action="blah.php" method="post">
First Name: <input type="text" name="first_name" /><br />
Last Name: <input type="text" name="last_name" /><br />
E-Mail: <input type="text" name="email" /><br />
Phone: <input type="text" name="phone" />
</form>

PHP:

<?php

if (isset($_POST['first_name']) && isset($_POST['last_name']) && isset($_POST['email']) && isset($_POST['phone']) && !empty($_POST['first_name']) &7 !empty($_POST['last_name']) && !empty($_POST['email']) && !empty($_POST['phone'))
{

$errors = array();

if (!ereg("^[^@ ]+@[^@ ]+\.[^@ ]+$", $_POST['email'])
{
    $errors[] = "Invalid E-Mail Address!";
}

if (!ereg("((\(\d{3}\)?)|(\d{3}))([\s-./]?)(\d{3})([\s-./]?)(\d{4})", $_POST['phone'])
{
    $errors[] = "Invalid Phone Number!";
}

if (!empty($errors))
{
    foreach ($errors as $error)
{
    echo $error . "<br />";
}
} else {
    echo "First Name: " . $_POST['first_name'] . "<br />";
    echo "Last Name: " . $_POST['last_name'] . "<br />";
    echo "E-Mail : " . $_POST['email'] . "<br />";
    echo "Phone: " . $_POST['phone'] . "<br />";
}
}
?>

PHP:

Kind of sloppy.. and I didn't test the REGEX I just nabbed them from RegexLib.

 

Now that CodyRo did most of the work for you, don't forget to split the prize money half half.

Peace,
