Reads through a whole directory(via the opendir, readdir and closedir system calls) and returns either the names or an array in result
argument of callback
function, depending on the flags
argument.
Directory path.
Combination of EIO_READDIR_* constants.
The request priority: EIO_PRI_DEFAULT
, EIO_PRI_MIN
, EIO_PRI_MAX
, or NULL
. If NULL
passed, pri
internally is set to EIO_PRI_DEFAULT
.
callback
function is called when the request is done. It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);
Arbitrary variable passed to callback
.
eio_readdir() returns request resource on success, or FALSE
on error. Sets result
argument of callback
function according to flags
:
-
EIO_READDIR_DENTS
(integer) - eio_readdir() flag. If specified, the result argument of the callback becomes an array with the following keys: 'names' - array of directory names 'dents' - array of struct eio_dirent-like arrays having the following keys each: 'name' - the directory name; 'type' - one of EIO_DT_* constants; 'inode' - the inode number, if available, otherwise unspecified;
-
EIO_READDIR_DIRS_FIRST
(integer) - When this flag is specified, the names will be returned in an order where likely directories come first, in optimal stat order.
-
EIO_READDIR_STAT_ORDER
(integer) - When this flag is specified, then the names will be returned in an order suitable for stat'ing each one. When planning to stat() all files in the given directory, the returned order will likely be fastest.
-
EIO_READDIR_FOUND_UNKNOWN
(integer)
Node types:
-
EIO_DT_UNKNOWN
(integer) - Unknown node type(very common). Further stat() needed.
-
EIO_DT_FIFO
(integer) - FIFO node type
-
EIO_DT_CHR
(integer) - Node type
-
EIO_DT_MPC
(integer) - Multiplexed char device (v7+coherent) node type
-
EIO_DT_DIR
(integer) - Directory node type
-
EIO_DT_NAM
(integer) - Xenix special named file node type
-
EIO_DT_BLK
(integer) - Node type
-
EIO_DT_MPB
(integer) - Multiplexed block device (v7+coherent)
-
EIO_DT_REG
(integer) - Node type
-
EIO_DT_NWK
(integer) -
EIO_DT_CMP
(integer) - HP-UX network special node type
-
EIO_DT_LNK
(integer) - Link node type
-
EIO_DT_SOCK
(integer) - Socket node type
-
EIO_DT_DOOR
(integer) - Solaris door node type
-
EIO_DT_WHT
(integer) - Node type
-
EIO_DT_MAX
(integer) - Highest node type value
<?php /* Is called when eio_readdir() finishes */ function my_readdir_callback($data, $result) { echo __FUNCTION__, " called\n"; echo "data: "; var_dump($data); echo "result: "; var_dump($result); echo "\n"; } eio_readdir("/var/spool/news", EIO_READDIR_STAT_ORDER | EIO_READDIR_DIRS_FIRST, EIO_PRI_DEFAULT, "my_readdir_callback"); eio_event_loop(); ?>
The above example will output something similar to:
my_readdir_callback called data: NULL result: array(2) { ["names"]=> array(7) { [0]=> string(7) "archive" [1]=> string(8) "articles" [2]=> string(8) "incoming" [3]=> string(7) "innfeed" [4]=> string(8) "outgoing" [5]=> string(8) "overview" [6]=> string(3) "tmp" } ["dents"]=> array(7) { [0]=> array(3) { ["name"]=> string(7) "archive" ["type"]=> int(4) ["inode"]=> int(393265) } [1]=> array(3) { ["name"]=> string(8) "articles" ["type"]=> int(4) ["inode"]=> int(393266) } [2]=> array(3) { ["name"]=> string(8) "incoming" ["type"]=> int(4) ["inode"]=> int(393267) } [3]=> array(3) { ["name"]=> string(7) "innfeed" ["type"]=> int(4) ["inode"]=> int(393269) } [4]=> array(3) { ["name"]=> string(8) "outgoing" ["type"]=> int(4) ["inode"]=> int(393270) } [5]=> array(3) { ["name"]=> string(8) "overview" ["type"]=> int(4) ["inode"]=> int(393271) } [6]=> array(3) { ["name"]=> string(3) "tmp" ["type"]=> int(4) ["inode"]=> int(393272) } } }
