我正在使用 Sendgrid API 通过 PHP 发送电子邮件我可以一次发送到一封电子邮件，但是我需要将 $email 变量作为大量电子邮件传递

array(
         "email" => $email,
         "name" => $name
         )

$email 变量将参数设置为电子邮件的集合示例：$email="abc@mail.com,info@abc.com,def@gmail.com"

我该怎么做？

Answer 1

Heyho Gi,

您可以使用 implode() 将数组转换为字符串，这样您就可以将电子邮件作为数组获取，然后您可以说 $email = implode(",", $emails); 并且 $email 将是 abc@mail.com,info@abc.com,def@gmail.com。但是我不明白你为什么要用一个外部公司来打他的！您可以在您的机器上本地执行此操作！不要与其他公司共享太多数据 ;)

a) explode() 电子邮件值 , 将其转换为数组

b) 在此数组上应用循环并发送邮件。

c) 确保检查真实值而不是 $_POST['send']

<?php
    if (!empty($_POST['email']) && !empty($_POST['subject']))
    {
        $emails = explode(',',$_POST['email']);
        $subject = $_POST['subject'];
        $body = $_POST['message'];
        
        foreach($emails as $email){

            $data = array(
                "personalizations" => array(
                    array(
                        "to" => array(
                            array(
                                "email" => $email,
                                "name" => $name
                            )
                        )
                    )
                ) ,
                "from" => array(
                    "email" => $sender
                ) ,
                "subject" => $subject,
                "content" => array(
                    array(
                        "type" => "text/html",
                        "value" => $body
                    )
                )
            );
        
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, "https://api.sendgrid.com/v3/mail/send");
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            $response = curl_exec($ch);
            curl_close($ch);
        }
           
    
    }
    ?>
