imap_search
(PHP 4, PHP 5)
imap_search — This function returns an array of messages matching the given search criteria
说明
array imap_search
( resource $imap_stream
, string $criteria
[, int $options
[, string $charset
]] )
This function performs a search on the mailbox currently opened
in the given imap stream.
For example, to match all unanswered messages sent by Mom, you'd
use: "UNANSWERED FROM mom". Searches appear to be case
insensitive. This list of criteria is from a reading of the UW
c-client source code and may be incomplete or
inaccurate (see also » RFC2060,
section 6.4.4).
