    dba_fetch — Fetch data specified by key

    Açıklama

    dba_fetch(string|array $key, Dba\Connection $dba, int $skip = 0): string|false

    Overloaded signature deprecated as of 8.3.0:

    dba_fetch(string|array $key, int $skip, resource $dba): string

    dba_fetch() fetches the data specified by key from the database specified with dba.

    Bağımsız Değişkenler

    key

    The key the data is specified by.

    Bilginize:

    When working with inifiles this function accepts arrays as keys where index 0 is the group and index 1 is the value name. See: dba_key_split().

    dba

    A Dba\Connection instance, returned by dba_open() or dba_popen().

    skip

    The number of key-value pairs to ignore when using cdb databases. This value is ignored for all other databases which do not support multiple keys with the same name.

    Dönen Değerler

    Returns the associated string if the key/data pair is found, false otherwise.

    Sürüm Bilgisi

    Sürüm: Açıklama
    8.4.0 The dba parameter expects a Dba\Connection instance now; previously, a valid dba resource was expected.
    8.3.0 Calling dba_fetch() with dba as the 3rd argument is now deprecated.
    8.2.0 dba_fetch()'s optional skip argument is now at the end in line with PHP userland semantics. The previously overloaded signature is still accepted but discouraged.
