Well, I could update your perl code a bit, and try to help with your php
question at the same time...
first of all, i would use he following in perl to avoid the
ls system
call:
**************************************************************
$some_dir = "/your/dir/to/read/from/$author";
opendir(DIR, $some_dir) || die "can't opendir $some_dir: $!";
# sorts last modified time, most recent first, and only returns files in
the directory
@files = sort {(stat("$some_dir/$a"))[9] < (stat("$some_dir/$b"))[9]}
grep { -f "$some_dir/$_" } readdir(DIR);
closedir(DIR);
**************************************************************
so, given the perl version... here's the php version:
**************************************************************
$some_dir = "/your/dir/to/read/from/" . $author;
$DIR = opendir($some_dir) || die "can't opendir $some_dir: $!";
while (false!==($file = readdir($DIR))) {
if (filetype($some_dir . "/" . $file) == "file") {
$mtime = filemtime ($some_dir . "/" . $file);
$files[$some_dir."/".$file] = $mtime;
}
}
closedir($DIR);
asort ($files);
reset ($files);
**************************************************************
PHP's filemtime is equivalent to perl's (stat(<file>))[9], which returns
the modification time of a file.
PHP's filetype($file) is equivalent to the grep check in Perl for file
type of file.
All the others are identical.
enjoy,
johnny p.
