title: Prevent PHP From Waiting for mail() function
body: <p>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?</p>
  
  <p>Thanks,</p>
