with this code I get filename from the current folder
<?php
$mydir = dirname(__FILE__);
$myfiles = array_diff(scandir($mydir), array('.', '..'));
$arrsingleresult = str_replace('.php', '', $myfiles);
print_r($arrsingleresult);
?>
Now how can I get filenames from one folder back ? (../ like this) any work around ?
Please use double time dirname() function to back one level
dirname(dirname(__FILE__));

I have several files in a folder and i want to count them.
$folder = "images";
$allPics = scandir($folder);
$result = sizeof($allPics);
echo $result;
The result is 350 but it should be 348. I don't get it why it is showing me the result +2?
Am i missing something?!
http://php.net/manual/en/function.scandir.php
When looking at the documentation you can see the function return both '.' and '..', that's why you're having 2 more than you should have.
You can use this:
array_diff(scandir($folder), array('..', '.'));
To get rid of the dots you don't wanna have.
You are using the unix system and it have, 2 pointers in each directory, the pointer for the parent dirrectory that usualy is notted with .. and the pointer to the current directory that is notted as .
I have my php code as follows:
<?php include("/myfolder/my-file-01.html"); ?>
and in the folder myfolder I have 2 files: my-file-01.html and my-file-02.html
Now, with jQuery or php, how can I randomly include my-file-01.html or my-file-02.html in one refresh my website (F5).
Any Idea?
Thanks
As an alternative, you could also load them inside an array thru scandir, point it into the files path, then use an array_rand:
$path_to_files = 'path/to/myfolder/';
$files = array_diff(scandir($path_to_files), array('.', '..'));
$file = $files[array_rand($files)];
require "$path_to_files/$file";
However, if you have other files other than my-file prefix, it'll get mixed up, so to prevent that from happening, you could use a glob solution instead. This will only search file/s that has that my-file prefix. Example:
$files = glob('myfolder/my-file-*.html');
$file = $files[array_rand($files)];
require $file;
You generate a random number which is 1 or 2 with the rand() function.
<?php
//Create random number 1 or 2:
$random = rand(1,2);
//Add zero before 1 or 2
$random = "0".$random;
//Include random file:
include("/myfolder/my-file-".$random.".html");
See previous Question which was partly answered but there has been a change in requirements for the script: PHP - Exploding / Moving / Filename
i'm new to php and am stuck. I have loads of files that look like this:
2014-04-01 NS122345 - The date, the initials of the person and there employee code.
I want to be able to move the files that have NS or JB Or GA into there relevant folder/directories. So for NS it would go into the Nathan Saunders Folder, for JB into the Joe Bailey folder.
My directory structure looks like this:
root/wan/upload - Where files/images/docs are stored. Inside upload folder i have:
>2014-04-08 NS6565.doc
>2012-01-03 JB8932.doc
>2013-02-01 GA5434.doc
>etc
root/wan/administrator/components/com_upload - where my code is stored
This is my php code for moving, creating and checking the filename and putting it in the correct folder:
$dir = JPATH_BASE . DS . "upload";
$folders = array('SE528733B'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/528733B','SE125673B'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/125673B','SE3452312'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/3452312');
$files = scandir($dir);
foreach($files AS $file){
if(!is_file($dir.DS.$file)){ continue; }
$array = explode(' ', $file);
if(count($array)<2){ continue; }
$firstTwoLetters = substr($array[1], 0, 9);
$foldername = $firstTwoLetters;
if(is_dir($folders[$firstTwoLetters])||mkdir($foldername[$firstTwoLetters],0777, 1))
rename($dir.DS.$file,$foldername[$firstTwoLetters].DS.$file);
That code currently reads the filename if its already in the array "folders" it moves to the correct folder, I have changed it recently to make the folder automatically reading whatever file is in the upload section, but the problem comes when making the folder, the mkdir seems to make the directory:
1) in the wrong place it makes it where the code is stored which is in the com_upload section instead of making it in the upload folder.
2) Names it wrong it takes the first letter not the letters or numbers after it. E.g. "2014-04-08 NS6565.doc", makes the directory "N"
Any help to fixing those 2 problems would be great.
Thanks,
1) If you want to create the directory in another place or you use a relative path from the directory your code is or you use an absolute path.
2) When you are creating the directory you use $foldername but it isn't a name of any directory. It's instead the name of the file. Also, you use it as an array when it's a string (so it only take one char)
Try this:
$dir = JPATH_BASE . DS . "upload";
$folders = array('SE528733B'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/528733B','SE125673B'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/125673B','SE3452312'=>'/var/www/vhosts/test.cariss.co.uk/httpdocs/wan/upload/3452312');
$files = scandir($dir);
foreach($files AS $file){
if(!is_file($dir.DS.$file)){ continue; }
$array = explode(' ', $file);
if(count($array)<2){ continue; }
$firstTwoLetters = substr($array[1], 0, 9);
$foldername = substr($firstTwoLetters,0,2);
if(is_dir($dir. DS . $foldername)||mkdir($dir. DS . $foldername,0777, 1))
rename($dir.DS.$file,$dir . DS . $foldername . DS.$file);
I have a double question. Part one: I've pulled a nice list of pdf files from a directory and have appended a file called download.php to the "href" link so the pdf files don't try to open as a web page (they do save/save as instead). Trouble is I need to order the pdf files/links by date created. I've tried lots of variations but nothing seems to work! Script below. I'd also like to get rid of the "." and ".." directory dots! Any ideas on how to achieve all of that. Individually, these problems have been solved before, but not with my appended download.php scenario :)
<?php
$dir="../uploads2"; // Directory where files are stored
if ($dir_list = opendir($dir))
{
while(($filename = readdir($dir_list)) !== false)
{
?>
<p><a href="http://www.duncton.org/download.php?file=login/uploads2/<?php echo $filename; ?>"><?php echo $filename;
?></a></p>
<?php
}
closedir($dir_list);
}
?>
While you can filter them out*, the . and .. handles always come first. So you could just cut them away. In particular if you use the simpler scandir() method:
foreach (array_slice(scandir($dir), 2) as $filename) {
One could also use glob("dir/*") which skips dotfiles implicitly. As it returns the full path sorting by ctime then becomes easier as well:
$files = glob("dir/*");
// make filename->ctime mapping
$files = array_combine($files, array_map("filectime", $files));
// sorts filename list
arsort($files);
$files = array_keys($files);
How do I get the name of the last file (alphabetically) in a directory with php? Thanks.
Using the Directories extension you can do it simply with
$all_files = scandir("/my/path",1);
$last_files = $all_files[0];
The scandir command returns an array with the list of files in a directory. The second parameter specifies the sort order (defaults to ascending, 1 for descending).
<?php
$dir = '/tmp';
$files = scandir($dir, 1);
$last_file = $files[0];
print($last_file);
?>
Code here looks like it would help - would just need to use end($array) to collect the last value in the generated array.
$files = scandir('path/to/dir');
sort($files, SORT_LOCALE_STRING);
array_pop($files);
