PHP: Get list of all filenames contained within my images directory [duplicate]

This question already has answers here: How to read a list of files from a folder using PHP? [closed] (9 answers) Closed 7 years ago.开发者_如何转开发

I have been trying to figure out a way to list all files contained within a directory. I'm not quite good enough with php to solve it on my own so hopefully someone here can help me out.

I need a simple php script that will load all filenames contained within my images directory into an array. Any help would be greatly appreciated, thanks!

Try glob

Something like:

 foreach(glob('./images/*.*') as $filename){
     echo $filename;
 }

---

scandir() - List files and directories inside the specified path

$images = scandir("images", 1);
print_r($images);

Produces:

Array
(
    [0] => apples.jpg
    [1] => oranges.png
    [2] => grapes.gif
    [3] => ..
    [4] => .
)

---

Either scandir() as suggested elsewhere or

• glob() — Find pathnames matching a pattern

Example

$images = glob("./images/*.gif");
print_r($images);

/* outputs 
Array (
   [0] => 'an-image.gif' 
   [1] => 'another-image.gif'
)
*/

Or, to walk over the files in directory directly instead of getting an array, use

• DirectoryIterator — provides a simple interface for viewing the contents of filesystem directories

Example

foreach (new DirectoryIterator('.') as $item) {
    echo $item, PHP_EOL;
} 

To go into subdirectories as well, use RecursiveDirectoryIterator:

$items = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator('.'),
    RecursiveIteratorIterator::SELF_FIRST
);

foreach($items as $item) {
    echo $item, PHP_EOL;
}

To list just the filenames (w\out directories), remove RecursiveIteratorIterator::SELF_FIRST

You can also use the Standard PHP Library's DirectoryIterator class, specifically the getFilename method:

 $dir = new DirectoryIterator("/path/to/images");
 foreach ($dir as $fileinfo) {
      echo $fileinfo->getFilename() . "\n";
 }

This will gives you all the files in links.

<?php
$path = $_SERVER['DOCUMENT_ROOT']."/your_folder/"; 

$files = scandir($path);
$count=1;
foreach ($files as $filename)
{
    if($filename=="." || $filename==".." || $filename=="download.php" || $filename=="index.php")
    {
        //this will not display specified files
    }
    else
    {
        echo "<label >".$count.".&nbsp;</label>";
        echo "<a href="download.php/?filename=".$filename."">".$filename."</a>
";
        $count++;
    }
}
?>

Maybe this function can be useful in the future. You can manipulate the function if you need to echo things or want to do other stuff.

$wavs = array();
$wavs = getAllFiles('folder_name',$wavs,'wav');

$allTypesOfFiles = array();
$wavs = getAllFiles('folder_name',$allTypesOfFiles);

//explanation of arguments from the getAllFiles() function
//$dir -> folder/directory you want to get all the files from.
//$allFiles -> to store all the files in and return in the and.
//$extension -> use this argument if you want to find specific files only, else keept empty to find all type of files.

function getAllFiles($dir,$allFiles,$extension = null){
    $files = scandir($dir);
    foreach($files as $file){           
        if(is_dir($dir.'/'.$file)) {
            $allFiles = getAllFiles($dir.'/'.$file,$allFiles,$extension);
        }else{
            if(empty($extension) || $extension == pathinfo($dir.'/'.$file)['extension']){
                array_push($allFiles,$dir.'/'.$file);
            }
        }
    }
    return $allFiles;
}
