we can read a file’s metadata for example, permissions and ownership with PHP’s stat() function, Which returns information about a file in a array format.
stat() returns associative array with information about file. see the below list
NOTE : To force PHP to reload the file’s metadata, call clearstatcache( ), which flushes PHP’s cached information.
| 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 ** |
Example

echo "File type: ." . substr(strrchr( $file, "."), 1) . "

echo "Filesize: " . round(( $fileinfo[ "size" ] / 1024 ), 1) . "k
"; // size in bytes
echo "Last accessed: " . date("H:i:s, d/m/y", $fileinfo["atime"]) . "
"; // time of last access (Unix timestamp)
echo "Last Modified: " . date("H:i:s, d/m/y", $fileinfo["mtime"]); // time of last modification (Unix timestamp)
