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.
Note: The results of this
function are cached. See clearstatcache() for
more details.
Note: This function will not work on
remote files as the file to
be examined must be accessible via the servers filesystem.
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));
}
?> |
