Sending SMS from a Web Application Using PHP

Sending SMS messages directly from a web application is a common requirement in many scenarios. PHP provides a range of options for integrating SMS functionality into your application.

How to Enable SMS Sending:

To send SMS messages from PHP, you will need the following:

• A web hosting provider that supports PHP and the ability to send emails
• A dedicated email address
• A list of carrier email addresses corresponding to phone numbers

Steps to Send SMS:

1. Find the Carrier Email Address:

Determine the mobile carrier of the recipient's phone number. Each carrier has a specific email format that you need to use, such as "[email protected]" for AT&T.

2. Craft the SMS Email:

Compose an email with the recipient's phone number as the recipient address. The subject of the email will be the SMS message body. For example, an email to "[email protected]" with the subject "Test SMS" will send "Test SMS" to the recipient.

3. Send the Email:

Use the PHP mail() function to send the email. Ensure that the from address is set to the dedicated email address you created.

Example PHP Code:

$to = "[email protected]";
$from = "[email protected]";
$subject = "Test SMS";

mail($to, $subject, "", "From: $from");

This code will send an SMS message with the content "Test SMS" to the recipient's phone number on the specified carrier.
