imap_gc — Clears IMAP cache
Purges the cache of entries of a specific type.
Eine von imap_open() zurückgegebene IMAP-Verbindung.
Specifies the cache to purge. It may one or a combination of the following constants: IMAP_GC_ELT (message cache elements), IMAP_GC_ENV (enveloppe and bodies), IMAP_GC_TEXTS (texts).
Returns TRUE.
Beispiel #1 imap_gc() example
<?php
$mbox = imap_open("{imap.example.org:143}", "username", "password");
imap_gc($mbox, IMAP_GC_ELT);
?>
If you notice that you're program's memory usage is increasing (as observed using ps) while calling the imap functions, calling this function should free that memory.
