The emailing part is fine but I've never had to write a file with PHP before. The file is only required for the duration of the script and doesn't need to be kept permanently. You never have to write or delete a file to the disk. PHP Manual: Filesystem. If you only need it so that you can attach it to an email, you don't really have to write the file. I pulled that out of a script I use to send myself backups. How are we doing? Please help us improve Stack Overflow.

For qmail users, I have written a function that talks directly to qmail-queue, rather than going through the sendmail wrapper used by mail.
Thus it allows more direct control over the message for example, you can adapt the function to display "undisclosed recipients" in to the To: header. It also performs careful validation of the e-mail addresses passed to it, making it more difficult for spammers to exploit your scripts.
This is mostly unnecessary because qmail will ignore any additional To: headers injected by a malicious user. However if you have some strange mail setup it might be a problem. The function returns false if the message fails validation or is rejected by qmail-queue, and returns true on success. If you are using the sendmail app from an exim package or something you don't really need to change the normal parameters PHP gives it -t -i as other posts described.
I just added "-f myemail example. One thing that got me stuck for a few hours was trying to figure out why the return-path was set as the user user running php and not what I was setting it with the -f option then I later found at that in order to forcefully set the return-path the user account running the command must be in exim's trusted users configuration!
When I sent mail manually this was not an issue. Unlike Sendmail, qmail requires locally-injected messages to use Unix newlines LF only. This is a common problem with PHP scripts. So now, I can go back to sending emails with text AND html components :. I haven't fully tested it like with microtime with long mails. I send html message as 7-bit, so I didn't try yet with html. If you have good html practise, you don't really need to encode html as quote-printable as it only uses 7-bit chars. Simply setting From: email address.
So to subscribe to mylist example. I've noticed that on some versions of PHP occasionally mail returns the empty string for success, rather than true or false. The empty string evaluates to false. Note, that single line should not contain more than 78 character, but is not allowed to contain more than characters. The possible consequences are: Over 78 - clients are allowed to display the message in a "harder to read" way. Over - clients and servers are allowed to drop the message or cause any buffer-limit error.
The ideal workaround is to use the smtp functions which servers allow because of its better audit trail. Alternatively call the mail function several times. I've just spent about four hours trying to work out what I was doing wrong!! Just a comment on some of the examples, and as a note for those who may be unaware.
It takes whatever is sent from the browser, so don't trust this for the image type. Here's a function that I have used to get a nice simple array of all incoming files from a page. Note that this function loses the file input names I usually process the files just by type. In checking the error code, you probably ought to check for code 4.
I believe Code 4 means no file was uploaded, and there are many instances where that's perfectly OK. Such as when you have a form with multiple data items, including file and image uploads, plus whatever else. The user might not be adding a new upload for whatever reason, such as there may already be a file in the system from an earlier update, and the user is satisfied with that.
For quick debugging eg. Obviously don't use these for comparison in real code. Nontypicall array comes in php after the submission.
