PHP – Send Secure E-Mails to Stop E-Mail Injections

Created and implemented a PHP Filter Function which will Stop E-mail Injections.

To stop e-mail injections I have added an input validator that checks the “email” field when the form is submitted.

Filters are used in PHP to filter and validate external data (Like E-mail Address) which is coming from insecure sources.

Filter Function

Demo – Contact Us Form

filter_var is used to filters a variable with a specified filter.

FILTER_SANITIZE_EMAIL is used to sanitizing and validating email address. It removes all the unwanted characters including blank space from the string. It also removes all the illegal e-mail characters from a string.

FILTER_VALIDATE_EMAIL is used to validates input value as e-mail address.
