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=SE_FREE [, string $charset=NIL ]] )

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).
