``` smtp_code:"stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages:\nerror:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed" ``` 原因是php5.6后默认开启SLL验证 解决办法 , 在配置文件中, ``` $mail = new PHPMailer(true); $mail->SMTPOptions = [ 'ssl' => array( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true, ) ]; ```
