How to set smtp server in php mail

To set up an SMTP server in PHP mail, you'll need to configure the mail() function or use a PHP mail library that supports SMTP. Here are the general steps:

Using the mail() function

Define the SMTP server settings:

$smtp_server = 'your_smtp_server';
$smtp_port = 587; // or 25, 465, etc.
$smtp_username = 'your_smtp_username';
$smtp_password = 'your_smtp_password';

Set the mail() function to use the SMTP server:

ini_set('SMTP', $smtp_server);
ini_set('smtp_port', $smtp_port);
ini_set('auth_username', $smtp_username);
ini_set('auth_password', $smtp_password);

Use the mail() function to send the email:
```
mail('[email protected]', 'Subject', 'Message');
```
Using a PHP mail library

There are many PHP mail libraries available, such as PHPMailer, SwiftMailer, and Zend_Mail. Here's an example using PHPMailer:

Install PHPMailer using Composer: composer require phpmailer/phpmailer

Create a PHPMailer object:


require 'PHPMailer/PHPMailer.php';
require 'PHPMailer/SMTP.php';

$mail = new PHPMailer\PHPMailer\PHPMailer(); $mail->isSMTP();

3. Set the SMTP server settings:
```php
$mail->Host = $smtp_server;
$mail->Port = $smtp_port;
$mail->SMTPAuth = true;
$mail->Username = $smtp_username;
$mail->Password = $smtp_password;

Set the email message:

$mail->setFrom('[email protected]', 'Your Name');
$mail->addAddress('[email protected]', 'Recipient Name');
$mail->Subject = 'Subject';
$mail->Body = 'Message';

Send the email:
```
$mail->send();
```
Common SMTP server settings

Here are some common SMTP server settings:

your_smtp_server: Your email provider's SMTP server (e.g., smtp.gmail.com, smtp.outlook.com, etc.)
smtp_port: The port number used by the SMTP server (e.g., 587, 25, 465, etc.)
smtp_username: Your email address or username
smtp_password: Your email password

Troubleshooting tips

Make sure your SMTP server settings are correct and your email provider allows SMTP authentication.
Check your email provider's documentation for specific SMTP server settings and authentication requirements.
Verify that your PHP script has the necessary permissions to send emails.
Use a PHP error log or a debugging tool to troubleshoot any issues with your email sending code.
