PHP Email Validation

Simple PHP code to validate emails server side

I wrote this code 2 years ago

It's a simple way to protect your contact form from spam emails

1. Validate Email Format (blah@abc.tld)
2. Ping Email Domain to make sure it's online
3. Validate Email Provider from the list
   • Gmail.com
   • Hotmail.com
   • Outlook.com
   • msn.com
   • Outlook.sa
   • aol.com
   • protonmail.com

How to use

if(isValid("user@hotmail.com")){

  echo "This is a valid email";
  
} else {

  echo "Please enter a valid email";
  
}
