The fstat() function returns information about an open file.
This function will return an array containing the following elements:
[0] or [dev] - device number
[1] or [ino] - inode number
[2] or [mode] - inode protection mode
[3] or [nlink] - number of connections
[4] or [uid] - The user ID of the owner
[5] or [gid] – The owner’s group ID
[6] or [rdev] - inode device type
[7] or [size] - file size in bytes
[8] or [atime] - last access time (Unix timestamp)
[9] or [mtime] - last modified time (Unix timestamp)
[10] or [ctime] - Last inode change time (Unix timestamp)
[11] or [blksize] - Block size for file system IO (if supported)
[12] or [blocks] - number of occupied blocks
fstat(file)
| parameter | describe |
|---|---|
| file | Required. Specifies the open file to be checked. |
Note: The results returned from this function are not the same as server-to-server results. This array contains numeric indexes, name indexes, or both.
Tip: The fstat() function is roughly similar to the stat() function. The only difference is that the file must be open when the fstat() function is used.
<?php$file = fopen("test.txt","r");print_r(fstat($file));fclose($file);?>The above code will output:
Array([0] => 0[1] => 0[2] => 33206[3] => 1[4] => 0[5] => 0[6] => 0[7] => 92 [8] => 1141633430[9] => 1141298003[10] => 1138609592[11] => -1[12] => -1[dev] => 0[ino] => 0[mode] => 33206[nlink] => 1[uid] => 0[gid] => 0[rdev] => 0[size] => 92[atime] => 1141633430[mtime] => 1141298003[ctime] => 1138609592[blksize] => -1[blocks] => -1)
