PHP Registration with Email Verification

1 0 Thursday, June 20, 2019

PHP Email verification is most important because its check the email reality actually that the email is a real email or a fake email.

Email Verification: 

Normally when we create an account on any website after the account creation they want email verification, and actually, email verification is very very important. actually, they want to check your email is a real email or a fake email, so very straight forward email verification just checks your email reality.


php email verification

What we will cover in the article? 

  1. PHP Registration and login form
  2. PHP Email verification
  3. PHP Form Validation Library
  4. Object-Oriented Programming 
  5. PHPMailer library
First of all, we will create a PHP registration form with email verification and as well the login form,
and for the form validation actually, we will use the form validation library which we have already created the form validation library and another we will use object-oriented programming paradigm. we will verify the user email so for sending the email basically we will use the PHPMailer library and it's very easy to send an email.

PHPMailer library setting:

Before sending an email with PHPMailer library first we have to do some settings. by default, Gmail does not allow the third party libraries to use your account for security reason, so now we need tell to Gmail that the PHPMailer library can use our Gmail account. follow the below steps
  1. Login to your Gmail account that account you have provided in the PHPMailer library
  2. Now we have to enable the less secure app so simply click here and ON less secure app
