Alright so I have use the PHP mail() function pretty extensively, however for my new site I will need to collect a filled fillable pdf file downloaded from my site, pull it from the files array, then send it to my e-mail so I can look at it later. I can do all of it except attach the .pdf file. How would I go about this? Please don't give me complete code because that is too easy. I wan't to figure it out myself but the tutorials simply don't explain what is happening.
