Опис

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.

Параметри

key: The key the data is specified by.

Зауваження:
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: Примірник Dba\Connection, якого повертає функція dba_open() або 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.

Значення, що повертаються

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

Версія	Опис
8.4.0	Тепер параметр `dba` має бути примірником Dba\Connection. раніше очікувався дійсний `dba` resource.
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.
