# imap_body

(PHP 4, PHP 5, PHP 7, PHP 8)

imap_body — Read the message body

### 说明

imap_body(IMAP\Connection `$imap`, int `$message_num`, int `$flags` = 0): string|false

imap_body() returns the body of the message, numbered `message_num` in the current mailbox.

imap_body() will only return a verbatim copy of the message body. To extract single parts of a multipart MIME-encoded message you have to use imap_fetchstructure() to analyze its structure and imap_fetchbody() to extract a copy of a single body component.

### 参数

`imap`

  IMAP\Connection 实例。

`message_num`

  The message number

`flags`

  The optional `flags` are a bit mask with one or more of the following:

  - `FT_UID` - The `message_num` is a UID
  - `FT_PEEK` - Do not set the \Seen flag if not already set
  - `FT_INTERNAL` - The return string is in internal format, will not canonicalize to CRLF.

### 返回值

Returns the body of the specified message, as a string, 或者在失败时返回 `false`.
