How to send emails using php script

How to send emails using php script
Sending emails using a PHP script can be accomplished using the built-in mail() function, which allows you to send emails directly from your web server. Here's a step-by-step guide on how to send emails using PHP:

Set Up Your Server:
Make sure you have access to a web server with PHP support. You can use a local development environment like XAMPP or a remote web hosting service.

Create an HTML Form (Optional):
If you want to collect user input and send emails based on that input, you can create an HTML form in your PHP file. For example:

html

input type="text" name="recipient" placeholder="Recipient Email"
input type="text" name="subject" placeholder="Subject"
textarea name="message" placeholder="Message"/textarea
input type="submit" value="Send Email"
/form

In the same directory as your HTML form or as a separate file, create a PHP script to handle the email sending:

php

?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$recipient = $_POST["recipient"];
$subject = $_POST["subject"];
$message = $_POST["message"];


if (mail($recipient, $subject, $message, $headers)) {
echo "Email sent successfully.";
} else {
echo "Email could not be sent.";
}
}
?

Configure Email Headers:
Customize the headers as needed. Be sure to set the "From" header to a valid email address from your domain.

Test the Script:
Upload the HTML form and the PHP script to your server. Access the HTML form through a web browser, fill in the fields, and submit the form. The PHP script will process the form data and attempt to send the email.

Please note:

The mail() function's success doesn't guarantee email delivery; it just means the email was handed off to the server's mail system. Actual delivery depends on various factors, including your server's configuration and the recipient's email server.
Sending emails directly from a web server might not be the best solution for production applications due to potential issues with spam filters and deliverability. Consider using third-party email services like SendGrid or PHPMailer for more robust email handling.

Always sanitize and validate user inputs to prevent security vulnerabilities. Additionally, ensure your server's email configuration is properly set up for sending emails.
