Method 1:check email using regular expression. // PHP email checker
// Function to validate email using regular expression function email_validation ( $str ) { return (! preg_match ( "^ [_ a-z0 -9 -] + (. [_ A-z0-9 -] +) * @ [a-z0-9 -] + (. [A-z0-9 -] +) * (. [Az] {2,3 }) $^ " , $str ))? FALSE: TRUE; }
// function call if (! email_validation ( "[email protected]" )) { echo "Invalid email address." ; } else { echo " Valid email address. " ; }
?> Exit:Valid email address ...
Explanation:In the above example, sending an email to a user-defined email_validation ($email) function that uses this example and matches a regular expression using the predefined function preg_match(). This predefined function matches all input against a regular expression and returns True if a match is found, otherwise it returns False.Method 2:check email using the filter_var() method.
// Declare the variable and initialize
// send it to email $email = " [email protected] " ;
// Verify email address if (filter_var ( $email , FILTER_VALIDATE_EMAIL)) { echo ( " $email is a valid email address " ); } else { echo ( "$email is not a valid email address" ); }
?> Exit:author @ engineerforengineer .com is a valid email address
Explanation:In the above example, passing the input email address to the predefined function filter_var(), which takes two parameters as the input email and the second - it is a type of email filter. This function filters email and returns true or false.Method 3:check email using the FILTER_SANITIZE_EMAIL filter.
// Declare a variable and save it by email $email = "[email protected]" ;
// Remove all invalid characters from email $email = filter_var ( $email , FILTER_SANITIZE_EMAIL);
// Verify email address if (filter_var ( $email , FILTER_VALIDATE_EMAIL)) { echo ( " $email is a valid email address " ); } else { echo ( "$email is not a valid email address" ); }
?> Exit:author.gfg @ GeeksforGeeks.com is a valid email address
Explanation:In the above example, use the FILTER_SANITIZE_EMAIL filter to remove all unsupported characters, and then use the FILTER_VALIDATE_EMAIL filter to validate the email.
