int filemtime (string $filename) DESCRIPTION
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. PARAMETERS
o $filename - Path to the file. RETURN VALUES
Returns the time the file was last modified, or FALSE on failure. The time is returned as a Unix timestamp, which is suitable for the date(3) function. EXAMPLES
Example #1 filemtime(3) 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)); } ?> ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
Note Note that time resolution may differ from one file system to another. Note The results of this function are cached. See clearstatcache(3) for more details. Tip As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine which wrappers support stat(3) family of functionality. SEE ALSO
