Not much explanation needed here:
<?php
$file = “yourfilegoeshere.php”;
$fileinfo = stat( $file );
echo “File name: ” . $file . “<br />\t”;
echo “File type: .” . substr( strrchr( $file, “.” ), 1 ) . “<br />\n”;
echo “Filesize: ” . round( ( $fileinfo[ "size" ] / 1024 ), 1 ) . “k<br />\n”; // size in bytes
echo “Last accessed: ” . date( “H:i:s, d/m/y”, $fileinfo[ "atime" ] ) . “<br />\n”; // time of last access (Unix timestamp)
echo “Last Modified: ” . date( “H:i:s, d/m/y”, $fileinfo[ "mtime" ] ) . “<br />\n”; // time of last modification (Unix timestamp)
