STAT

Gives information about a file

SYNTAX

stat ( string $filename ) : array

PARAMETERS

filename

Path to the file.

RETURN

NUMERIC ASSOCIATIVE 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 512-byte blocks allocated **

* On Windows this will always be 0.

** Only valid on systems supporting the st_blksize type - other systems (e.g. Windows) return -1.

*** On Windows, as of PHP 7.4.0, this is the serial number of the volume that contains the file, which is a 64-bit unsigned integer, so may overflow. Previously, it was the numeric representation of the drive letter (e.g. 2 for C:) for stat(), and 0 for lstat().

**** On Windows, as of PHP 7.4.0, this is the identifier associated with the file, which is a 64-bit unsigned integer, so may overflow. Previously, it was always 0.

The value of mode contains information read by several functions. When written in octal, starting from the right, the first three digits are returned by chmod(). The next digit is ignored by PHP. The next two digits indicate the file type:

MODE IN OCTAL MEANING
0120000 link
0100000 regular file
0060000 block device
0040000 directory
0010000 fifo

So for example a regular file could be 0100644 and a directory could be 0040755. In case of error, stat() returns FALSE.

Note: Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB.
