阻止PHP等待mail()函数 [英] Prevent PHP From Waiting for mail() function

问题描述

在我的Web应用程序中，当用户更改其帐户时，我调用php mail()函数向该用户发送电子邮件通知.实施此操作后，我发现帐户更改操作需要花费大量时间(> 20秒)才能完成.我怀疑这是因为PHP等待mail()函数发送电子邮件.有没有什么方法可以进行此调用而无需等待并立即继续下一行代码?

In my web application, when a user makes a change to their account, I call the php mail() function to send that user an email notification. After implementing this, I found that the account change action takes a very large amount of time (>20 seconds) to complete. I suspect that this is because PHP waits for the mail() function to send the email. Is there any way to make this call without waiting and immediately continue to the next line of code?

谢谢

推荐答案

创建另一个PHP脚本(在本示例中，我们将其称为"mailuser.php").在此文件中，您的代码将查找尚未通过电子邮件发送的已激活帐户...然后发送电子邮件.

Create another PHP script (we'll call it "mailuser.php" for this example). In this file your code would look for activated accounts that haven't been emailed yet... then send the email.

使用您的原始代码(激活帐户后)致电:

In your original code (after activating the account) call :

exec("php mailuser.php > /dev/null 2>&1 &");

这应该产生该进程，但不要等待它返回.

This should spawn the process, but not wait for it to return.

您还可以选择在命令行上传递用户ID，这样mailuser.php不必根据字段/标志查找用户.

You could also elect to pass the user id on the command line, so that the mailuser.php doesn't have to look for the users based on a field/flag.
