Description
array
stat ( string filename )
Gathers the statistics of the file named by
filename. If filename
is a symbolic link, statistics are from the file itself, not the
symlink. lstat() is identical to
stat() except it would instead be based off the symlinks
status.
In case of error, stat() returns FALSE. It also
will throw a warning.
Returns an array with the statistics of the file with the
following elements. This array is zero-based. In addition to
returning these attributes in a numeric array, they can be accessed
with associative indices, as noted next to each parameter; this is
available since PHP 4.0.6:
Table 1. stat() and fstat() result
format
| Numeric | Associative (since PHP 4.0.6) | Description |
|---|
| 0 | dev | device number |
| 1 | ino | inode number |
| 2 | mode | inode protection mode |
| 3 | nlink | number of links |
| 4 | uid | userid of owner |
| 5 | gid | groupid of owner |
| 6 | rdev | device type, if inode device * |
| 7 | size | size in bytes |
| 8 | atime | time of last access (Unix timestamp) |
| 9 | mtime | time of last modification (Unix timestamp) |
| 10 | ctime | time of last inode change (Unix timestamp) |
| 11 | blksize | blocksize of filesystem IO * |
| 12 | blocks | number of blocks allocated |
* - only valid on systems supporting the st_blksize type--other
systems (i.e. Windows) return -1.
Note: The results of this
function are cached. See clearstatcache() for
more details.
Tip: As of PHP 5.0.0 this function
can also be used with some URL wrappers. Refer to
Appendix M for a listing of which wrappers support
stat() family of functionality.

fstat(),
filemtime(), and
filegroup().
