send email with attachment in php without saving the file to webserver
问题 I am creating a simple form that let user "upload" a file, and a comments box. after the user choose the file(can be image or pdf) and click submit, i am not gonna store the file into my web server, the file will be inserted into an email and send to me. my question is: how can i attach the file without storing it in any place. I don't want to use third party module. Update: $attachment = $_FILES["OrderList"]["tmp_name"]; $content = file_get_contents($attachment); $content = chunk_split
