Introduction to php

Creating (Declaring) PHP Variables:


In PHP, a variable starts with the $ sign, followed by the name of the variable.
Example-

$x
$chotho

Classes and Objects in php


Basic class definitions begin with the keyword class, followed by a class name, followed by a pair of curly braces which enclose the definitions of the properties and methods belonging to the class.
Example-

class Chotho
{
       // property declaration
       public $var = 'a default value';
       // method declaration
       public function displayVar() {
           echo $this->var;
       }
}

How to Install PHPMailer library

PHPMailer is available on Packagist (using semantic versioning), and installation via composer is the recommended way to install PHPMailer. Just add this line to your composer.json file:

"phpmailer/phpmailer": "~6.0"

or run

composer require phpmailer/phpmailer

After Installation check whether you have all these files in PHPMailer folder

If any of the file is missing then please repeat the installation process.

Steps to write a code to Send Email in php

1)Create a file Mail.php

2)Include PHPMailer library in "Mail.php"

require_once('YourPathToPHPMailerFolder/PHPMailerAutoload.php');

3)Create a class Mail in "Mail.php"

class Mail
{
       public static function sendMail($subject, $body, $address) {
         //Create a new PHPMailer instance
         $mail = new PHPMailer;
         //Tell PHPMailer to use SMTP
         $mail->isSMTP();
         //Enable SMTP debugging
         // 0 = off (for production use)
        // 1 = client messages
        // 2 = client and server messages
        $mail->SMTPDebug = 2;
         //Ask for HTML-friendly debug output
        $mail->Debugoutput = 'html';
        //Set the hostname of the mail server
        $mail->Host = 'smtp.gmail.com';
        // use
        // $mail->Host = gethostbyname('smtp.gmail.com');
        // if your network does not support SMTP over IPv6
        //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
        $mail->Port = 587;
        //Set the encryption system to use - ssl (deprecated) or tls
        $mail->SMTPSecure = 'tls';
        //Whether to use SMTP authentication
        $mail->SMTPAuth = true;
        //Username to use for SMTP authentication - use full email address for gmail
        $mail->Username = "[email protected]";
        //Password to use for SMTP authentication
        $mail->Password = "yourpassword";
        //Set who the message is to be sent from
        $mail->setFrom('[email protected]', 'First Last');
        //Set an alternative reply-to address
        $mail->addReplyTo('[email protected]', 'First Last');
        //Set who the message is to be sent to
        $mail->addAddress('[email protected]', 'John Doe');
        //Set the subject line
        $mail->Subject = $subject;
        $mail->Body = $body;
        //Read an HTML message body from an external file, convert referenced images to embedded,
        //convert HTML into a basic plain-text alternative body
        //$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
        //Replace the plain text body with one created manually
        $mail->AltBody = 'This is a plain-text message body';
        //Attach an image file
        //$mail->addAttachment('images/phpmailer_mini.png');
        //send the message, check for errors
        if (!$mail->send()) {
            echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
            echo "Message sent!";
        }
    }

4)Create an object of class "Mail"

$m = new Mail();

5)Call "sendMail()" function of class "Mail" with subject, your message** & sender's email id as parameter

$m->sendMail("My first mail",
             "This is a testing mail",
             "[email protected]");

Write the Codes as follows:

How to create HTML Template
