Email Validation
Here is a nice little php function that will validate email addresses which is ideal for forms / registration on your website. The function provides an optional parameter to check the email against MX records for the domain in the email address.

{
if(eregi("^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email))

Sending Hebrew Mail to Outlook
A few weeks ago I had a client that needed a PHP contact form, no problem right. Wrong, the thing is he wanted to receive mails in Hebrew. I set it all up and worked fine in Thunderbird, Gmail, etc… , but would not display the Hebrew in MS Outlook. After hours of testing and searching I finally found a solution. The issue was the message headers, setting just the charset and mime type did not work, the content-language also needed to be set. Below is the snippet.
<?php // Your Email Address $ax_mailTo = 'you@tld.com'; // Contact Form Title $ax_mailSubject = '[Contact Form]' . $_POST['subject']; // IMPORTANT The base encoded subject, this prevents the title printing gibberish. $subject = "=?UTF-8?B?".base64_encode($ax_mailSubject)."?="; // Name from Contact Form $name = $_POST['contactName']; // Message from Contact Form $message = $_POST['message']; // The email contents. $body = ' Name: ' . $name . ' Email: ' . $email . ' Comments: ' . $message . ' '; // The message headers $headers = "From: $ax_mailTo" . "\r\n"; $headers .= "Reply-To: $ax_mailTo" . "\r\n"; $headers .= "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-language: he" . "\r\n"; $headers .= "Content-type: text/plain; charset=UTF-8"; // Send the mail mail($ax_mailTo, $subject, $body, $headers); ?>

Send Text Messages via PHP
Sending text messages with PHP is pretty much identical to sending an email using the built-in PHP function mail(). Instead of using an email address, however, you must use a combination of the phone number you are sending to as well as the hostname for the carrier.
Send Text Msg with PHP Mail Function
Note the use of 5558675309@txt.att.net as where the email address would usually be. For a list of all carriers’ host names and more info, visit the snippet source below.
<?php
mail("5558675309@txt.att.net", "", "Your packaged has arrived!", "From: FirstName LastName <emailaddy@somedomain.com>\r\n");
?>
