PHP - Code to traverse a directory and get all the files(images)

Question

i want to write a page that will traverse a specified directory.... and get all the files in that directory...

in my case the directory will only contain images and display the images with their links...

something like this

How to Do it

p.s. the directory will not be user input.. it will be same directory always...

Answer 1

You'll want to use the scandir function to walk the list of files in the directory.

Answer 2

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            echo "$file\n";
        }
    }
    closedir($handle);
}

use readdir

Answer 3

$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents if (is_dir($dir)) { if ($dh = opendir($dir)) { while (($file = readdir($dh)) !== false) { echo "filename: $file : filetype: " . filetype($dir . $file) . "\n"; } closedir($dh); } }

/**
*  function get files 
*  @param $path string = path to fine files in 
*  @param $accept array = array of extensions to accept 
*  @param currentLevel = 0, stopLevel = 0 
*  @return array of madmanFile objects, but you can modify it to 
*  return whatever suits your needs.  
*/

    public static function getFiles( $path = '.', $accept, $currentLevel = 0, $stopLevel = 0){

            $path = trim($path);                    //trim whitespcae if any
            if(substr($path,-1)=='/'){$path = substr($path,0,-1);}  //cutoff the last "/" on path if provided
            $selectedFiles = array();
            try{
                    //ignore these files/folders
                    $ignoreRegexp = "/\.(T|t)rash/";
                    $ignore = array( 'cgi-bin', '.', '..', '.svn');
                    $dh = @opendir( $path );
                    //Loop through the directory
                    while( false !== ( $file = readdir( $dh ) ) ){
                            // Check that this file is not to be ignored
                            if( !in_array( $file, $ignore ) and !preg_match($ignoreRegexp,$file)){
                            $spaces = str_repeat( ' ', ( $currentLevel * 4 ) );
                                    // Its a directory, so we need to keep reading down...
                                    if( is_dir( "$path/$file" ) ){
                                            //merge current selectFiles array with recursion return which is
                                            //another array of selectedFiles
                                            $selectedFiles = array_merge($selectedFiles,MadmanFileManager::getFiles( "$path/$file", $accept, ($currentLe$
                                    } else{
                                            $info = pathinfo($file);
                                            if(in_array($info['extension'], $accept)){
                                                    $selectedFiles[] = new MadmanFile($info['filename'], $info['extension'], MadmanFileManager::getSize($

                                            }//end if in array
                                    }//end if/else is_dir
                            }
                    }//end while
                    closedir( $dh );
                    // Close the directory handle
            }catch (Exception $e){
                    echo 'Caught exception: ',  $e->getMessage(), "\n";
            }

            return $selectedFiles;
    }

Answer 5

You could as others have suggested check every file in the dir, or you could use glob to identify files based on extension.

Answer 6

I use something along the lines of:

if ($dir = dir('images'))
{       
    while(false !== ($file = $dir->read()))
    {
        if (!is_dir($file) && $file !== '.' && $file !== '..' && (substr($file, -3) === 'jpg' || substr($file, -3) === 'png' || substr($file, -3) === 'gif'))
        {
            // do stuff with the images
        }
    }
}
else { echo "Could not open directory"; }

Answer 7

You could also try the glob function:

$path = '/your/path/';
$pattern = '*.{gif,jpg,jpeg,png}';

$images = glob($path . $pattern, GLOB_BRACE);

print_r($images);

Answer 8

Hi you can use DirectoryIterator

try {
    $dir = './';
    /* @var $Item DirectoryIterator */
    foreach (new DirectoryIterator($dir) as $Item) {
        if($Item->isFile()) {
            echo $Item->getFilename() . "\n";
        }
    }
} catch (Exception $e) {
    echo 'No files Found!<br />';
}

If you want to pass directories recursively: http://php.net/manual/en/class.recursivedirectoryiterator.php

Answer 9

<?php 
//define directory
$dir = "images/";
//open directory
if ($opendir = opendir($dir)){
//read directory
 while(($file = readdir($opendir))!= FALSE ){
  if($file!="." && $file!= ".."){
   echo "<img src='$dir/$file' width='80' height='90'><br />";
  }
 }
} 
?>
