Description
int
filemtime ( string filename)
Returns the time the file was last modified, or FALSE in case of
an error. The time is returned as a Unix timestamp, which is
suitable for the date() function.
The results of this function are cached. See
clearstatcache() for more details.
This function will not work on remote files; the file to
be examined must be accessible via the server's filesystem.
Note: This function returns the time when the data
blocks of a file were being written to, that is, the time
when the content of the file was changed.
Example 1. filemtime() example <?php
// outputs e.g. somefile.txt was last modified: December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename));
}
?> |
