PHP: Gives information about a file

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.

Parameters

filename: Path to the file.

Return Values

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 (e.g. Windows) return -1.

In case of error, stat() returns FALSE.

Errors/Exceptions

Upon failure, an E_WARNING is emitted.

ChangeLog

Version Description

4.0.6 In addition to returning these attributes in a numeric array, they can be accessed with associative indices, as noted next to each parameter
