Have the following script.
<?php
if ($handle = opendir('files/')) {
while (false !== ($fileName = readdir($handle))) {
$newName = str_replace("SKU#","",$fileName);
rename(fileName, $newName);
}
closedir($handle); } ?>
my script is in the root directory of iss.
inetpub/wwwroot
And I am trying to as a result access the folder files/, which is one level up to wwwroot. Where contains one image called:
"WV1716BNSKU#.zoom.1"
I am using a windows OS, any idea why this is not working, code looks file.
What error do you get? Make sure PHP is setup to display all errors.
Your script will also have to be in the same folder as your files you want to rename as all your paths are relative.
Try this:
if ($handle = opendir('./')){
while (false !== ($fileName = readdir($handle))){
$newName = str_replace("SKU#", "", $fileName);
rename($fileName, $newName);
}
closedir($handle);
}

Hello stackoverflow community;
I'm trying to display a few files in a directory using php and coming unstuck:
In my file ('salad') I have three recipe files ('recipe1.txt', recipe2.txt, 'recipe3.txt') and I want to display them so I'm writing the following:
$script = opendir('salad');
while(false !==($file = readdir($script))) {
if (is_file($file)) {
echo "<p>$file</p>";
}
}
Unfortunately this only echos to the screen .DS_store, what am i doing wrong?
You could use this:
<?php
$dir = "/tmp"; // put what suits you here
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;
}
sort($files);
print_r($files);
rsort($files);
echo"$files";
?>

new php programmer here. I have been trying to rename all the files in a folder by replacing the extension.
The code I'm using is from the answer to a similar question on SO.
if ($handle = opendir('/public_html/testfolder/')) {
while (false !== ($fileName = readdir($handle))) {
$newName = str_replace(".php",".html",$fileName);
rename($fileName, $newName);
}
closedir($handle);
}
I get no errors when running the code, but no changes are made to the filenames.
Any insight on why this isn't working? My permission settings should allow it.
Thanks in advance.
EDIT: I get a blank page when checking the return value of rename(), now trying something with glob() which might be a better option than opendir...?
EDIT 2: With the 2nd code snippet below, I can print the contents of $newfiles. So the array exists, but the str_replace + rename() snippet fails to change the filename.
$files = glob('testfolder/*');
foreach($files as $newfiles)
{
//This code doesn't work:
$change = str_replace('php','html',$newfiles);
rename($newfiles,$change);
// But printing $newfiles works fine
print_r($newfiles);
}
Here is the simple solution:
PHP Code:
// your folder name, here I am using templates in root
$directory = 'templates/';
foreach (glob($directory."*.html") as $filename) {
$file = realpath($filename);
rename($file, str_replace(".html",".php",$file));
}
Above code will convert all .html file in .php
You're probably working in the wrong directory. Make sure to prefix $fileName and $newName with the directory.
In particular, opendir and readdir don't communicate any information on the present working directory to rename. readdir only returns the file's name, not its path. So you're passing just the file name to rename.
Something like below should work better:
$directory = '/public_html/testfolder/';
if ($handle = opendir($directory)) {
while (false !== ($fileName = readdir($handle))) {
$newName = str_replace(".php",".html",$fileName);
rename($directory . $fileName, $directory . $newName);
}
closedir($handle);
}
Are you sure that
opendir($directory)
works? Have you checked that? Because it seems there might be some Document Root missing here...
I would try
$directory = $_SERVER['DOCUMENT_ROOT'].'public_html/testfolder/';
And then Telgin's solution:
if ($handle = opendir($directory)) {
while (false !== ($fileName = readdir($handle))) {
$newName = str_replace(".php",".html",$fileName);
rename($directory . $fileName, $directory . $newName);
}
closedir($handle);
}
That happens if the file is opened. Then php cannot do any changes to the file.
<?php
$directory = '/var/www/html/myvetrx/media/mydoc/';
if ($handle = opendir($directory)) {
while (false !== ($fileName = readdir($handle))) {
$dd = explode('.', $fileName);
$ss = str_replace('_','-',$dd[0]);
$newfile = strtolower($ss.'.'.$dd[1]);
rename($directory . $fileName, $directory.$newfile);
}
closedir($handle);
}
?>
Thank you so much for the suggestions. it's working for me!
I am trying to read a file name current.conf and then use the name of a folder saved in it to opendir(); when I open:
$file = fopen("current.conf","r");
$lines = fread($file,"10");
fclose($file);
$lines = "/".$lines."/";
echo $lines;
$dir=opendir($lines);
$files=array();
while (($file=readdir($dir)) !== false)
{
if ($file != "." and $file != ".." and $file != "index.php")
{
array_push($files, $file);
}
}
closedir($dir);
The current.conf has only one line in it:
2.1-2328
I am not able to open the folder that is named in the conf files. I have a feeling it has to do with the formatting of the conf file but not sure.
I suspect the directory doesn't exist (or you don't have the rights to read it), but without a specific error (opendir is most likely throwing an E_WARNING - check your logs, etc.)
Incidentally, you could re-write your code to reduce its complexity as follows:
<?php
// Grab the contents of the "current.conf" file, removing any linebreaks.
$dirPath = '/'.trim(file_get_contents('current.conf')).'/';
$fileList = scandir($dirPath);
if(is_array($fileList)) {
foreach($fileList as $file) {
// Skip the '.' and '..' in here as required.
echo $file."\n";
}
}
else echo $dirPath.' cound not be scanned.';
?>
In this instance the call to scandir will throw an E_WARNING.
I am trying to make a function that scans a folder for subfolders and then returns
a numeric array with the names of those folders.
This is the code i use for testing. Once i get it to print out the folder names and not just "." and ".." for present and above folder all will be well, and I can finish the function.
<?php
function super_l_getthemes($dir="themes")
{
if ($handle = opendir($dir)) {
echo "Handle: {$handle}\n";
echo "Files:\n";
while (false !== ($file = readdir($handle))) {
echo "{$file}<br>";
}
closedir($handle);
}
?>
The above code works fine, and prints out all the contents of the folder: files, subfolders and the "." and ".."
but if i replace:
while (false !== ($file = readdir($handle))) {
echo "{$file}<br>";
}
with:
while (false !== ($file = readdir($handle))) {
if(file_exists($file) && is_dir($file)){echo "{$file}";}
}
The function only prints "." and ".." , not the two folder names that I'd like it to print.
Any help is appreciated.
You must provide the absolute path to file_exists, otherwise it will look for it in the current execution path.
while (false !== ($file = readdir($handle))) {
$file_path = $dir . DIRECTORY_SEPARATOR . $file;
if (file_exists($file_path) && is_dir($file_path)) {
echo "{$file}";
}
}
The problem with readdir is that it only reads the strings of the named entries inside of the directory.
For instance, if you had file "foo" inside of directory "/path/to/files/", when using readdir on "/path/to/files/", you would eventually come to the string "foo".
Normally this wouldn't be a problem if it were in the same directory as the current working directory of the script, but, since you are reading from an arbitrary director, when you are attempting to inspect the entry (file, directory, whatever), you are calling is_dir on the bare string "foo".
I would try prefixing the name you pull out using readdir with the path to the file.
if ($handle = opendir($dir)) {
echo "Handle: {$handle}\n";
echo "Files:\n";
while ($file = readdir($handle)) {
/*** make $file into an absolute path ***/
$absolute_path = $dir . '/' . $file;
/*** NOW try stat'ing it ***/
if (is_dir($absolute_path)) {
/* it's a directory; do stuff */
}
}
closedir($handle);
}
You need to use:
while (false !== ($file = readdir($handle))) {
if(file_exists($dir.'/'.$file) && is_dir($dir.'/'.$file)){echo "{$file}";}
}
See http://php.net/readdir
If you only want the directories of the starting folder, you can simply do:
glob('/some/path/to/search/in/*', GLOB_ONLYDIR);
which would given you only those foldernames in an array. If you want all directories below a given path, try SPL's RecursiveDirectoryIterator
$fileSystemIterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('/some/path/to/look/in'),
RecursiveIteratorIterator::SELF_FIRST);
Iterators can be used with foreach:
$directories = array();
foreach($fileSystemIterator as $path => $fileSystemObject) {
if($fileSystemObject->isDir()) {
$directories[] = $path;
}
}
You will then have an array $directories with all directories under the given path.
$files = array();
foreach(new DirectoryIteraror('/path') as $file){
if($file->isDir() /* && !$file->isDot()*/) $files[] = $file->getFilename();
}
[edit: though you wanted to skip the dot, commented it out)
I don't think you need both file_exists and is_dir,
You just need the is_dir function. From the manual:
is_dir Returns TRUE if the filename exists and is a directory, FALSE otherwise.
Use this:
while (false !== ($file = readdir($handle))) {
if(is_dir($file)){echo "{$file}";}
}
is_dir will also check whether it's a relative path or an absolute path.
$directory = scandir($path);
foreach($directory as $a){
if(is_dir($path.$a.'/') && $a != '.' && $a != '..'){
echo $a.'<br/>';
}
}
With the path given as shown, it displays the folders present in the path.
I agree with nuqqsa's solution, however, I'd like to add something to it.
Instead of specifying the path, you can change the current directory instead.
For example,
// open directory handle
// ....
chdir($dir);
while (false !== ($file = readdir($handle)))
if(is_dir($file))
echo $file;
// close directory handle
I have this PHP script which i'm grabbing images from a directory and displaying them. The directory only has 4 image files in it and yet there are 6 li's. In firebug the images just have the paths 'Images/uploaded/.' and 'Images/uploaded/..'
Are there hidden files that this script is grabbing but not displaying correctly?
<?php
$dir = 'Images/uploaded/';
if($handle = opendir($dir)) {
while(false !== ($file = readdir($handle))) {
echo "<li><img class=\"thumb\" src=\"".$dir.$file."\" /></li>";
}
}
closedir($handle);
?>
Your test for . or .. fails... example: You load '.' and your test says:
if('." is not "." OR its not "..")
change this conditional to && (and).
Those are the entries for "current directory" and "parent directory, respectively. Just filter them out.
