note 94622 added to function.mail

Is it possible to set up a delayed message? I have users signing up on a site, then registering to be volunteers on specific dates. How do I set up a reminder e-mail with PHP that will send to everyone on a specific date and time? ---- Server IP: 208.69.120.35 Probable Submitter: 69.150.209.13 ---- Manual Page -- http://www.php.net/manual/en/function.mail.php Edit -- https://master.php.net/note/edit/94622 Del: integrated -- https://master.php.net/note/delete/94622/integrated Del: useless -- https://master.php.net/note/delete/94622/useless Del: bad code -- https://master.php.net/note/delete/94622/bad+code Del: spam -- https://master.php.net/note/delete/94622/spam Del: non-english -- https://master.php.net/note/delete/94622/non-english Del: in docs -- https://master.php.net/note/delete/94622/in+docs Del: other reasons-- https://master.php.net/note/delete/94622 Reject -- https://master.php.net/note/reject/94622 Search -- https://master.php.net/manage/user-notes.php
