File Directory Listing

[Mundo]

$path = "/home/themungo/public_html/up/";
$dir_handle = @opendir($path) or die("Unable to open $path");
echo "Directory Listing of $path<br/>";
while ($file = readdir($dir_handle)) {
if($file!="." && $file!="..")
echo "<a href='$file'>$file</a><br/>";
}
closedir($dir_handle);

 

So heres a simple piece of code that lists the contents of a directory... Now is there any way I could have just the newest 20 files listed, not the whole directory?

[dezkit]

yes there is a way

[Mundo]

To ask the obvious question... How? Without the use of MySQL...

Hey,

 

I can't give you a super "do this" answer as I'm learning myself, but here is some info on how to order by date.  You could then limit it to the first 20 items.

Hope this is useful for you.

# list_dir_files.php 
# 
#    This is a compilation and modification of  
#    several scripts, snippets, tutorials and 
#    examples from the manual 
# 
#    Major credit goes to phpDIRList 2.0 - (c)2005 Ulrich S. Kapp :: Systemberatung :: web-programmierung 
# 
#    The script reads through a given folder 
#    and displays the files contained therein 
# 
#    There are five variables you may alter 
# 
#    1.    $allowed_ext - this array is used to set which 
#        type of file will be listed 
# 
#    2.    $directory - this is used to set which directory 
#        will be searched/listed 
# 
#    3.    $do_link - TRUE means display the file 
#        name as a link to the file; FALSE means 
#        do NOT make the name a link 
# 
#    4.    $sort_what - this determines what the 
#        data will be sorted upon: 0 is by name; 
#        1 is by size; 2 is by date last modified 
# 
#    5.    $sort_how - describes how to sort;  
#        0 means to sort ASCENDING  
#        (oldest to newest, smallest to largest, Z to A);  
#        while 1 means to sort DESCENDING 
#        (newest to oldest, largest to smallest, A to Z)

<?
$path = '/home/themungo/public_html/up/';
# Initialise list arrays, files and array counters for them
$t = 0;
$f = 0;
$images_arr['name'] = array();
$images_arr['time'] = array();

arsort( $images_arr['name'] );
}

//test
foreach ($images_arr['time'] as $key=>$ftime){
$fname = $images_arr['name'][$key];
echo '<strong>filename:</strong> '.$fname.' <strong>filetime:</strong> '.$ftime.'<br/>';
}?>

 

Ok that will display them in order... The last uploaded file is displayed first... Now how can i limit to "x" amount of results?

[DarkWater]

Change:

while (false!== ($file = readdir($handle))) {
if($file!= "." && $file!= "..") {
$fName = $file;
$file = $path.'/'.$file;
if(is_file($file)){
$images_arr['time'][$t++] = filemtime($file); //<---- here it is, just a seperate key in the array to store filetimes
$images_arr['name'][$f++] = $file;
};
};

 

To:

 

while ((false!== ($file = readdir($handle))) && $count < 20) {
if($file!= "." && $file!= "..") {
$fName = $file;
$file = $path.'/'.$file;
if(is_file($file)){
$images_arr['time'][$t++] = filemtime($file); //<---- here it is, just a seperate key in the array to store filetimes
$images_arr['name'][$f++] = $file;
};
};
$count++;
}

 

You can change the amount in the while loop if you want.

		$fName = $file;
		$file = $path.'/'.$file;
			if(is_file($file)){
			$images_arr['time'][$t++] = filemtime($file); //

	};

}


foreach ($images_arr['time'] as $key=>$ftime){
$fname = $images_arr['name'][$key];
echo '<strong>filename:</strong> '.$fname.' <strong>filetime:</strong> '.$ftime.'<br/>';
}

?>

 

This however, gets the oldest 15 files and sorts them in order... Not grabs the newest 15... Any help?

[Mundo]

I hate to bump... But anybody?

[retro]

It is listing newest first for me.

 

However, it seems to be skipping some files - curious.

 

Here's a slightly more complex solution..

 

Revert back to the original code without the $count stuff.

 

Change the test code at the end to this:

 

//test
$i = 1;
foreach ($images_arr['time'] as $key=>$ftime){
$fname = $images_arr['name'][$key];
echo '<strong>filename:</strong> '.$fname.' <strong>filetime:</strong> '.$ftime.' <strong>i:</strong> '.$i.' <br/>';
if ($i == 15) {
echo "qwerty";
break;
}
$i++;
}

I'm sure someone will suggest something better, though!
