Find date of last modified file on website?

[HDFilmMaker2112]

Is there anyway to write a script that will find the file with the most recent file modified/uploaded date and return it?

 

I know I can use filemtime() to return the time from the specific file, but I need a way to find the last modified file.

Find the glob() function, but don't know if it's what I'm looking for...

On a *nix host, you can exec this: 

 

find . -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r | head -n 1

 

Replace the "." with whatever the parent directory is of the tree you need to check.  I'd probably do something like this:

 

$lastchanged = `/usr/bin/find /path_to_search  -type f -printf '%TY-%Tm-%Td %TT %p\n' | /usr/bin/sort -r | /usr/bin/head -n 1`;

 

Keep in mind that this is going to scan the filesystem everytime it's called, so if this is a large tree, that could be some substantial IO.  The filesystem is not an indexed database.  The results you get are going to look like this:

 

2011-06-11 12:42:55.0000000000 /home/david/foo.txt

 

So you would have to break the string into pieces but that is something done easily with explode.

I came up with this:

 

$files1 = glob("./ghosthuntersportal.com/*.php");
$files2 = glob("./ghosthuntersportal.com/includes/*.php");
$files3 = glob("./ghosthuntersportal.com/images/*");
$files=array_merge($files1, $files2, $files3);
if(is_array($files) && count($files) > 0)
{
    foreach($files as $file)
    {
     
$filetime=filemtime($file);
  
    }
}
$filetime=max($filetime);
$lastupdated="Last Updated: ".date ("F j, Y", filemtime($filetime));

 

But I get this error:

 

Warning: Wrong parameter count for max() in /home/zyquo/public_html/ghosthuntersportal.com/includes/func.php on line 32

 

It returns a date of Last Updated: December 31, 1969.

You're sending a string to the max() function. When only one parameter is sent to max(), it must be an array. This is because of the way you're assigning the value: $filetime = should be filetime[] =.

I tried this just to check, error:

Added the [] results in this:

 

Warning: max() [function.max]: Array must contain at least one element in /home/zyquo/public_html/ghosthuntersportal.com/includes/func.php on line 33

 

The $files Array seems to be blank.

[Pikachu2000]

Post the current code . . .

[HDFilmMaker2112]

$files1[] = glob("./ghosthuntersportal.com/*.php");
$files2[] = glob("./ghosthuntersportal.com/includes/*.php");
$files3[] = glob("./ghosthuntersportal.com/images/*");
$files[]=array_merge($files1, $files2, $files3);
if(is_array($files) && count($files) > 0)
{
    foreach($files as $file)
    {
     
$filetime[]=filemtime($file);

    }
}
$filetime=max($filetime);
$lastupdated="Last Updated: ".date ("F j, Y", $filetime);

 

This returns the below:

 

Warning: filemtime() [function.filemtime]: stat failed for Array in /home/zyquo/public_html/ghosthuntersportal.com/includes/func.php on line 27

glob takes a filesystem path. Do you actually have a directory named "ghosthuntersportal.com"?

[HDFilmMaker2112]

my full path to the folder is public_html/ghosthuntersportal.com/sub-folders

 

the code is contained in func.php which is in the includes sub-folder.

 

If I do:

 

glob("*.php");

 

Wouldn't it assume I'm looking for php files in the sub-folder the script is contained in? and not the main folder.

[Pikachu2000]

From your description, I think this is what you're after. Using a single dot signifies a path relative to the current directory, whereas a double dot indicates one directory above the current directory.

 

$files1[] = glob("../*.php");
$files2[] = glob("../includes/*.php");
$files3[] = glob("../images/*");

$files3[] = glob("../images/*");

 

Still no luck. Any other ways to accomplish this without glob()?

[Pikachu2000]

It works with glob, I've tested it locally. The issue here is your path, most likely. What is the output from this?

 

echo $_SERVER['DOCUMENT_ROOT'];

[HDFilmMaker2112]

It displays this:

 

/home/zyquo/public_html/ghosthuntersportal.com

[Pikachu2000]

Then let's try using that output to your advantage. This should work, assuming you've described the directory structure properly. See what happens with this code.

 

And why did you add square brackets to the $files1, $files2 and $files3 assignments?

 

$root = $_SERVER['DOCUMENT_ROOT'];

$files1 = glob("$root/*.php");
$files2 = glob("$root/includes/*.php");
$files3 = glob("$root/images/*");
$files =array_merge($files1, $files2, $files3);

if(is_array($files) && count($files) > 0) {
     foreach($files as $file) {
          $filetime[]=filemtime($file);
     }
}
$filetime=max($filetime);
$lastupdated="Last Updated: ".date ("F j, Y", $filetime);

works perfectly like that... just removed the echos and now it's absolutely perfect. Thanks.
