filemtime Questions

[xianaier]

I have been using filemtime to get the Last Modified date and time on specific files for my site. However, I would like to check the entire directory of my site in this manner but I am unsure if this is possible.

Also, is it possible to output the last time a site's database was updated, using this manner or any other? Since the code isn't updated very often, but the database is, I'd like to have it noted on the site when the last update of any sort happened.

Thanks in advance for any tips.

[ Examples with filemtime ] PHP 3, PHP 4, PHP 5

int filemtime ( string filename )

filemtime returns the last modification of the file filename , or FALSE on error.

filemtime returns the time of writing file data blocks. Use date of the result to get a human readable date of modification.

Example filemtime:

<? Php
/ / the output is: somefile.txt was last modified: December 29 2002 22:16:23.

$ filename = 'somefile.txt' ;
if ( file_exists ( $ filename )) {
echo "$ filename has been modified: " . date ( "F d YH: i: s." , filemtime ( $ filename ));
}
?>
