imap_search

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

imap_search — This function returns an array of messages matching the given search criteria

Descrizione

imap_search(
    IMAP\Connection $imap,
    string $criteria,
    int $flags = SE_FREE,
    string $charset = ""
): array|false

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 » RFC1176, section "tag SEARCH search_criteria").

Elenco dei parametri

imap

An IMAP\Connection instance.

criteria

ALL - return all messages matching the rest of the criteria
ANSWERED - match messages with the \\ANSWERED flag set
BCC "string" - match messages with "string" in the Bcc: field
BEFORE "date" - match messages with Date: before "date"
BODY "string" - match messages with "string" in the body of the message
CC "string" - match messages with "string" in the Cc: field
DELETED - match deleted messages
FLAGGED - match messages with the \\FLAGGED (sometimes referred to as Important or Urgent) flag set
FROM "string" - match messages with "string" in the From: field
KEYWORD "string" - match messages with "string" as a keyword
NEW - match new messages
OLD - match old messages
ON "date" - match messages with Date: matching "date"
RECENT - match messages with the \\RECENT flag set
SEEN - match messages that have been read (the \\SEEN flag is set)
SINCE "date" - match messages with Date: after "date"
SUBJECT "string" - match messages with "string" in the Subject:
TEXT "string" - match messages with text "string"
TO "string" - match messages with "string" in the To:
UNANSWERED - match messages that have not been answered
UNDELETED - match messages that are not deleted
UNFLAGGED - match messages that are not flagged
UNKEYWORD "string" - match messages that do not have the keyword "string"
UNSEEN - match messages which have not been read yet

flags

Valid values for flags are SE_UID, which causes the returned array to contain UIDs instead of messages sequence numbers.

charset

MIME character set to use when searching strings.

Valori restituiti

Returns an array of message numbers or UIDs.

Return false if it does not understand the search criteria or no messages have been found.

$msgnos = imap_search($imap, 'ALL');
$uids   = imap_search($imap, 'ALL', SE_UID);

The date format for e.g. SINCE is, according to rfc3501:date            = date-text / DQUOTE date-text DQUOTEdate-day        = 1*2DIGIT                    ; Day of monthdate-day-fixed  = (SP DIGIT) / 2DIGIT                    ; Fixed-format version of date-daydate-month      = "Jan" / "Feb" / "Mar" / "Apr" / "May" / "Jun" /                  "Jul" / "Aug" / "Sep" / "Oct" / "Nov" / "Dec"date-text       = date-day "-" date-month "-" date-yearSo a valid date is e.g. "22-Jul-2012" with or without the double quotes.

It has been noted that imap_search breaks with imap4 syntax.  To do an imap 4 search use curl and send a custom command, then grab the results.  Its best to do a UID search to get the unique IDs to work with later.  Here's an example with a working curl function.<?php$host = 'your-server.tld';$user = 'username';$pass = 'password';$folder = 'INBOX';function send_imap_command($server, $user, $pass, $command, $folder="INBOX"){   //Send an imap command directly to the imap server    $result=["response"=>"", "error"=>""];    $url = "imaps://$server/". rawurlencode($folder);    $options=[CURLOPT_URL=>$url, CURLOPT_PORT=> 993, CURLOPT_USERNAME=> $user,        CURLOPT_PASSWORD=> $pass, CURLOPT_RETURNTRANSFER=> true, CURLOPT_HEADER=> true,        CURLOPT_CUSTOMREQUEST=> $command];    $ch = curl_init();    curl_setopt_array($ch, $options);    $result["response"] = curl_exec($ch);    if(curl_errno($ch)) $response["error"]="Error (". curl_errno($ch) ."): ". curl_error($ch);    return $result;}//Pull out all the emails returned as undeliverable by the remote mail server in the inbox using curl$response=send_imap_command($host, $user, $pass,            'UID SEARCH SINCE "01-Jan-2022" (OR FROM "mailer-daemon" FROM "postmaster") (OR SUBJECT "fail" (OR SUBJECT "undeliver" SUBJECT "returned"))',            $folder);if($response["error"]!=""){    echo $response["error"]."\n";} elseif (strlen($response["response"])>5){    //Server returns a string in the form * SEARCH uid1 uid2 uid3 ...  Clean up and create array of UIDs.    $response["response"]=str_replace("* SEARCH ","",$response["response"]);    $messages=explode(" ",$response["response"]);}print_r($messages);?>

Hi, be aware, that imap_search() does NOT (as you may exspect) return an empty array, if nothing was found! As the manual says, it returns FALSE.Do not test the result like "count($array)" as I did. This gives you 1 for an empty result. Took me an hour to found out why :-(  RTFM

imap_search function is not fully compatible with IMAP4. the c-client used as of now supports only IMAP2 and some search criterion will not be available for use such as "OR"So a php code similar to:$inbox   = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'foo@example.com', 'pass123', OP_READONLY);$search_string = 'SUBJECT "FedEx" OR SUBJECT "USPS"';    $emails = imap_search($inbox, $search_string);will throw an error saying "Unknown search criterion"observations and reference:PHP source trace:(ref: https://github.com/php/php-src/blob/master/ext/imap/php_imap.c)    /ext/imap/php_imap.c -> line no : 4126    imap_search => line no : 4148c-client library source trace:src/c-client/mail.c -> line no : 3973internal.txt -> line no : 1919 => mail_criteria()    criteria IMAP2-format search criteria string    WARNING: This function does not accept IMAP4 search criteria.IMAP2 RFC1064 => [ref: https://tools.ietf.org/html/rfc1064] [page: 13]IMAP4 RFC2060 => [ref: http://www.faqs.org/rfcs/rfc2060.html] [section: 6.4.4]Note:The core search functionality in a core module(IMAP) is still not available in PHP. Hope this will be brought to the developer community's attention...

To set your own CHARSET, which is useful if you are dealing with Chinese Japanese and Korean queries.

<?php imap_search($inbox,'BODY "'.$keyword.'"', SE_FREE, "UTF-8"); ?>

Please be aware about UID of the message.It is NOT an ID that never change!If you move your message to another folder in your IMAP account, this UID WILL CHANGE. So if your message has UID = 100 (in INBOX folder) and you move it to some subfolder and then back to INBOX, it's new UID in INBOX will be 101.

This is the correct way to use the imap_search with ON "date"$date = date("j F Y");$emails = imap_search($inbox,'ON "'.$date.'"' );

imap_search() always returns false when op_silent flag is set in the connection parameters.
