[0] or [dev] - Device number
[1] or [ino] - Inode number
[2] or [mode] - Inode protection mode
[3] or [nlink] - Number of links

[6] or [rdev] - Inode device type
[7] or [size] - Size in bytes
[8] or [atime] - Last access (as Unix timestamp)

[10] or [ctime] - Last inode change (as Unix timestamp)
[11] or [blksize] - Blocksize of filesystem IO (if supported)
[12] or [blocks] - Number of blocks allocated

Syntax

file	Required. Specifies the file to check

Tips and Notes

Note: The results from this function will differ from server to server. The array may contain the number index, the name index, or both.

Note: The result of this function are cached. Use clearstatcache() to clear the cache.

Tip: This function is similar to fstat(), except that with this function the file does not have to be open.

Example

<?php
$file = fopen("test.txt","r");
print_r(stat($file));
fclose($file);
?>

The output of the code above could be:
