Answer 1

을

http://www.w3schools.com/php/filter_validate_email.asp :

if(!filter_var($email, FILTER_VALIDATE_EMAIL)) 
    { 
    echo "E-mail is not valid"; 
    } 
else 
    { 
    echo "E-mail is valid"; 
    } 

예를 들어 제공 한 이메일을 포함하여 좋은 이메일을 확인합니다.

Answer 2

이것에 대한 정규식이 필요하지 마십시오

// Find the last period in an email address 
$last_period_place = strrpos(".", $email); 
// Get everything after that 
$final_tld = substr($email, $last_period_place); 

그리고 당신이 관심이 있다면, 이메일 검증을위한 표준 준수 정규식 :
