你如何得到 php 发送一个 email

Question

I have a frontend in flutter that sends data to update mysql database in php. The form sends the data and the database updated just fine. However, it is bypassing or ignoring the section to send mail. I am not getting any errors for the mail. What am doing wrong?

<?php
    
    require_once('dbc.php');
    
    $name = $_POST["name"];
    $email= $_POST["email"];
    $phone= $_POST["phone"];
    $password = $_POST["password"];
    
    
    $findexist="select * from registered where name='$name'";
    
    $resultsearch=mysqli_query($conn,$find-exist);
    
    if(mysqli_num_rows($resultsearch)>0) {
        
        while($row=mysqli_fetch_array($resultsearch)) {
            $result["success"] = "3";
            $result["message"] = "user Already exist";
            echo json_encode($result);
            mysqli_close($conn);
        }
    } else {
        $sql = "INSERT INTO registered (name,email,phone,password) VALUES ('$name','$email','$phone','$password');";
        
        if ( mysqli_query($conn, $sql) ) {
            $result["success"] = "1";
            $result["message"] = "Registration success";
            echo json_encode($result);
            

            $to = $email;
            $subject = 'Signup | Verification';
            $message = 'Thanks for signing up with redhowler!';
        
            $headers = "MIME-Version: 1.0" . "\r\n";
            $headers = "Content-Type: text/html; charset=utf-8" . "\r\n";
        
            $headers .= 'From: redhowler2@gmail.com'. "\r\n";
        
            mail($to, $subject, $message, $headers);
            
            mysqli_close($conn);
      
        }
    }
    
?>

Try to use PHPMailer

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/phpmailer/phpmailer/src/Exception.php';
require 'vendor/phpmailer/phpmailer/src/PHPMailer.php';
require 'vendor/phpmailer/phpmailer/src/SMTP.php';
 $mail = new PHPMailer();
        $mail->IsSMTP();
        $mail->Mailer = "smtp";
        $mail->SMTPDebug  = 1;
        $mail->SMTPAuth   = TRUE;
        $mail->SMTPSecure = "tls";
        $mail->Port       = 587;
        $mail->Host       = "smtp.gmail.com";
        $mail->Username   = "xxxxxxxx@email.com";
        $mail->Password   = "xxxxxxxxxxxxxxx";

        $mail->IsHTML(true);
        $mail->AddAddress($to, "recipient-name");
        $mail->SetFrom("xxxxxxxxx@email.com", "from-name");
        $mail->AddReplyTo("xxxxxxxxx@email.com", "reply-to-name");
        $mail->Subject = $subject;
        $mail->MsgHTML($editor);




        if (!$mail->Send()) {
            echo "Error while sending Email.";
            var_dump($mail);
        } else {
            echo "Email sent successfully";
        }

For setting up send mail on your computer. I didn't use PHPmailer. I used mail(). Nevertheless, you have to have some knowledge of UNIX or Linux script -- according to the operating system. You also have to search(like google search) for "how to setup send mail on mac (enter operating system)". Links such as those mention below helped me:
