我正在开发一个项目，有两个过程。
我需要做所有这一切，但是要花很多时间。所以现在我正在考虑使用多线程。 谁能帮助您在php中实现这一目标？
我只需要尽快发送回复。 这是我的代码 我设置了一个发送邮件的功能，并且在成功发送完整邮件之后，我使用JSON编码向用户发送响应。
/ 邮件功能 /
public function emailSent($booking_id, $mailHeading, $smallHeading, $subject, $smallHeadingcustomer ,$status, $senttoestimator = true, $senttocustomer = true, $mailSent = false){
if(!empty($booking_id)){

if(!empty($bookingData)){
if(!empty($bookingData[0]['estimator_id']) && $bookingData[0]['estimator_id'] != 0){

$estimator_name = $name[0]['username'];
$estimator_mail = $name[0]['email'];
}
if($bookingData[0]['customer_id'] != 0){
$cname = $this->Cnc_model->getData('customers',array('name', 'office_contact_email'), array('id'=> $bookingData[0]['customer_id']));

这取决于您想走的深度。理想的方法是运行RabbitMQ或Gearman服务器并设置一个“发送邮件”作业供它们处理。提交作业非常快，并且可以使脚本完成并将响应发送回用户，但是当然这将涉及设置更多的基础结构，编写/维护更多的代码以处理该作业以及处理重试/错误状态。
问题最少的方法可能是运行将中继邮件的本地邮件服务器。移交应该非常快，可以提供更好的“有效”响应（至少用户会知道邮件已移交给本地邮件服务器）并允许脚本继续进行。如果电子邮件失败，则由本地邮件服务器将其作为对管理员或“发件人”用户的退回处理。
概述here的一种方法是先发送响应，然后再处理电子邮件-这意味着它永远不会向用户报告失败。不理想，但这取决于您的情况-也许管理员可以处理失败的消息并可以重新发送？

您可以使用ignore_user_abort（true）; 设置客户端断开连接是否应导致脚本中止。这将断开您当前的连接，然后将响应发送到前端，但仍执行其余代码。
ignore_user_abort(true);
ob_start();
echo "success";
$serverProtocole = filter_input(INPUT_SERVER, 'SERVER_PROTOCOL', FILTER_SANITIZE_STRING);
header($serverProtocole.' 200 OK');
header('Content-Encoding: none');
header('Content-Length: '.ob_get_length());
header('Connection: close');
ob_end_flush();
ob_flush();
flush();
最初对您的API使用后端验证，然后使用上面的代码发送响应，然后您可以编写代码通过电子邮件向用户发送电子邮件，这样，前端将获得响应，脚本将执行直到遇到返回或者死;这种方法的问题在于，如果在发送电子邮件时出错，则无法向前端发送响应。
否则，您可以在代码中使用邮件队列来稍后执行工作
