Memcache::add

    (PECL memcache >= 0.2.0)

    Memcache::add — Add an item to the server

    Beschreibung

    Memcache::add(
        string$key,
        mixed$var,
        int$flag = ?,
        int$expire = ?
    ): bool

    Memcache::add() stores variable var with key only if such key doesn't exist at the server yet. Also you can use memcache_add() function.

    Parameter-Liste

    key

    The key that will be associated with the item.

    var

    The variable to store. Strings and integers are stored as is, other types are stored serialized.

    flag

    Use MEMCACHE_COMPRESSED to store the item compressed (uses zlib).

    expire

    Expiration time of the item. If it's equal to zero, the item will never expire. You can also use Unix timestamp or a number of seconds starting from current time, but in the latter case the number of seconds may not exceed 2592000 (30 days).

    Rückgabewerte

    Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben. Returns false if such key already exist. For the rest Memcache::add() behaves similarly to Memcache::set().

    Beispiele

    Beispiel #1 Memcache::add() example

    <?php

    $memcache_obj     = memcache_connect("localhost", 11211);


    memcache_add($memcache_obj, 'var_key', 'test variable', false, 30);


    $memcache_obj->add('var_key', 'test variable', false, 30);

    ?>
