只獲取郵件的指定名稱

Question

我有一個preg_math的問題。所以我有這個梅索德：

public function filterUsers($a_users){ 

    $a_authorizedEmail = array(
     '@test.com', 
     '@test1.com' 
    ); 

    $a_response = array(); 
    foreach ($a_users as $user) { 
     if(false !== $email_user = EmailRepository::getEmail($user['id'])){ 
      foreach($a_authorizedEmail as $email){ 
       echo $email_user; 
       if(preg_match($email, $email_user)){ 
        $a_response[]= $user; 
       } 
      } 
     } 
    } 
    return $a_response; 
} 

的陣列$a_users：我有一個電子郵件hcost@test.com用戶。但在返回數組是空的。可能我沒有做出正確的驗證。請幫我

這樣做：

public function filterUsers($a_users){ 

    $a_authorizedEmail = array(
     '@test.com', 
     '@test1.com' 
    ); 
    $pattern = "/".implode("|",$a_authorizedEmail)."$/"; //Note the "/" start and end delimiter as well as the $ that indicates end of line 
    $a_response = array(); 
    foreach ($a_users as $user) { 
     $email_user = EmailRepository::getEmail($user['id']); 
     if(false !== $email_user){ 
      echo $email_user; 
      if(preg_match($pattern, $email_user)){ 
       $a_response[]= $user; 
      } 
     } 
    } 
    return $a_response; 
}
