stat
Gives information about a file
&reftitle.description;
arrayfalsestat
stringfilename
Gathers the statistics of the file named by
filename. If filename is a
symbolic link, statistics are from the file itself, not the symlink.
Prior to PHP 7.4.0, on Windows NTS builds the size,
atime, mtime and ctime
statistics have been from the symlink, in this case.
lstat is identical to stat
except it would instead be based off the symlinks status.

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:
<literal>mode</literal> file types
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;.

Upon failure, an E_WARNING is emitted.

&Version;
&Description;
7.4.0
On Windows, the device number is now the serial number of the volume that
contains the file, and the inode number is the identifier associated with the file.
7.4.0
The size, atime, mtime and
ctime statistics of symlinks are always those of the target.
This was previously not the case for NTS builds on Windows.
