What is the significance of including PEAR in PHP development?

PEAR (PHP Extension and Application Repository) is a framework and distribution system for reusable PHP components. Including PEAR in PHP development allows developers to easily access and use a wide range of pre-built libraries and packages, saving time and effort in coding common functionalities. PEAR also helps in promoting code reusability, standardization, and best practices in PHP development.

// Example of including a PEAR package in PHP
require_once 'Mail.php';

$from = "sender@example.com";
$to = "recipient@example.com";
$subject = "Hello!";
$body = "This is a test email.";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$mail = Mail::factory('smtp', array(
    'host' => 'smtp.example.com',
    'port' => 25,
    'auth' => true,
    'username' => 'username',
    'password' => 'password'
));

$mail->send($to, $headers, $body);
