Create a MIME message based on given envelope and body sections

Description

imap_mail_compose(array $envelope, array $bodies): string|false

Create a MIME message based on the given envelope and bodies sections.

Parameters

envelope

An associative array of header fields. Valid keys are: "remail", "return_path", "date", "from", "reply_to", "in_reply_to", "subject", "to", "cc", "bcc" and "message_id", which set the respective message headers to the given string. To set additional headers, the key "custom_headers" is supported, which expects an array of those headers, e.g. ["User-Agent: My Mail Client"].

bodies

An indexed array of bodies. The first body is the main body of the message; only if it has a type of TYPEMULTIPART, further bodies are processed; these bodies constitute the bodies of the parts.

**Body Array Structure**
Key	Type	Description
`type`	int	The MIME type. One of `TYPETEXT` (default), `TYPEMULTIPART`, `TYPEMESSAGE`, `TYPEAPPLICATION`, `TYPEAUDIO`, `TYPEIMAGE`, `TYPEMODEL` or `TYPEOTHER`.
`encoding`	int	The `Content-Transfer-Encoding`. One of `ENC7BIT` (default), `ENC8BIT`, `ENCBINARY`, `ENCBASE64`, `ENCQUOTEDPRINTABLE` or `ENCOTHER`.
`charset`	string	The charset parameter of the MIME type.
`type.parameters`	array	An associative array of `Content-Type` parameter names and their values.
`subtype`	string	The MIME subtype, e.g. `'jpeg'` for `TYPEIMAGE`.
`id`	string	The `Content-ID`.
`description`	string	The `Content-Description`.
`disposition.type`	string	The `Content-Disposition`, e.g. `'attachment'`.
`disposition`	array	An associative array of `Content-Disposition` parameter names and values.
`contents.data`	string	The payload.
`lines`	int	The size of the payload in lines.
`bytes`	int	The size of the payload in bytes.
