    (PHP 7 >= 7.3.0)

    Refresh extended operation helper

    说明

    ldap_exop_refresh(resource $link,string $dn,int $ttl): int

    Performs a Refresh extended operation and returns the data.

    参数

    $link

    An LDAP link identifier, returned by ldap_connect().

    $dn

    dn of the entry to refresh.

    $ttl

    Time in seconds(between 1 and 31557600)that the client requests that the entry exists in the directory before being automatically removed.

    返回值

    From RFC: The responseTtl field is the time in seconds which the server chooses to have as the time-to-live field for that entry. It must not be any smaller than that which the client requested, and it may be larger. However, to allow servers to maintain a relatively accurate directory, and to prevent clients from abusing the dynamic extensions, servers are permitted to shorten a client-requested time-to-live value, down to a minimum of 86400 seconds(one day).FALSE will be returned on error.

    The following workaround can be used to run the refresh command in PHP 7.2.
    $dn= 'cn=user,dc=test,dc=org';
    $ttl = 3600;
    $data = '';
    $data .= '80' . sprintf("%'.02x", strlen($dn)) . bin2hex($dn);
    $data .= '81' . sprintf("%'.02x", 4) . sprintf("%'.08x", $ttl);
    $data = hex2bin('30' . sprintf("%'.02x", strlen($data)/2) . $data);
    $success = ldap_exop($ldapHandle, LDAP_EXOP_REFRESH, $data);
