dba_fetch
(PHP 4, PHP 5, PHP 7, PHP 8)
dba_fetch — Fetch data specified by key
说明
Overloaded signature deprecated as of 8.3.0:
dba_fetch() fetches the data specified by
key from the database specified with
dba.
参数
-
key -
The key the data is specified by.
注意:
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 -
The database handler, 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.
返回值
Returns the associated string if the key/data pair is found, false
otherwise.
更新日志
| 版本 | 说明 |
|---|---|
| 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. |
