# filemtime

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

filemtime -- Gets file modification time

## 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.

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. Use date() on the result of this function to get a printable modification date for use in page footers.
