How to list files and folder in a dir (PHP) [duplicate]

Answer 1

use this function http://www.codingforums.com/showthread.php?t=71882

function getDirectory( $path = '.', $level = 0 ){

$ignore = array( 'cgi-bin', '.', '..' ); 
// Directories to ignore when listing output. Many hosts 
// will deny PHP access to the cgi-bin. 

$dh = @opendir( $path ); 
// Open the directory to the handle $dh 

while( false !== ( $file = readdir( $dh ) ) ){ 
// Loop through the directory 

    if( !in_array( $file, $ignore ) ){ 
    // Check that this file is not to be ignored 

        $spaces = str_repeat( ' ', ( $level * 4 ) ); 
        // Just to add spacing to the list, to better 
        // show the directory tree. 

        if( is_dir( "$path/$file" ) ){ 
        // Its a directory, so we need to keep reading down... 

            echo "<strong>$spaces $file</strong><br />"; 
            getDirectory( "$path/$file", ($level+1) ); 
            // Re-call this same function but on a new directory. 
            // this is what makes function recursive. 

        } else { 

            echo "$spaces $file<br />"; 
            // Just print out the filename 

        } 

    } 

} 

closedir( $dh ); 
// Close the directory handle 
}

and call the function like that

getDirectory( "." ); 
// Get the current directory 

getDirectory( "./files/includes" ); 
// Get contents of the "files/includes" folder

You may use Directory Functions: http://php.net/manual/en/book.dir.php

Simple example from opendir() function description:

<?php
$dir_path = "/path/to/your/dir";

if (is_dir($dir_path)) {
    if ($dir_handler = opendir($dir_path)) {
        while (($file = readdir($dir_handler)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir_path . $file) . "\n";
        }
        closedir($dir_handler);
    }
}
?>

LIST FILES IN FOLDER - 1 solution

<?php 
// open this directory 
$myDirectory = opendir(".");
// get each entry
while($entryName = readdir($myDirectory)) {
    $dirArray[] = $entryName;
}
// close directory
closedir($myDirectory);
//  count elements in array
$indexCount = count($dirArray);
Print ("$indexCount files<br>\n");
// sort 'em
sort($dirArray);
// print 'em
print("<TABLE border=1 cellpadding=5 cellspacing=0 class=whitelinks>\n");
print("<TR><TH>Filename</TH><th>Filetype</th><th>Filesize</th></TR>\n");
// loop through the array of files and print them all
for($index=0; $index < $indexCount; $index++) {
        if (substr("$dirArray[$index]", 0, 1) != "."){ // don't list hidden files
        print("<TR><TD><a href=\"$dirArray[$index]\">$dirArray[$index]</a></td>");
        print("<td>");  print(filetype($dirArray[$index])); print("</td>");
        print("<td>");  print(filesize($dirArray[$index])); print("</td>");
        print("</TR>\n");
    }
}
print("</TABLE>\n");
?>

<?PHP
# The current directory
$directory = dir("./");

# If you want to turn on Extension Filter, then uncomment this:
### $allowed_ext = array(".sample", ".png", ".jpg", ".jpeg", ".txt", ".doc", ".xls");

I've found in www.laughing-buddha.net/php/lib/dirlist/ a function that returns an array containing a list of a directory's contents.

Also look at php.net http://es.php.net/manual/es/ref.filesystem.php where you'll find additional functions for working with files in php.

Answer 5

If you have problems with accessing to the path, maybe you need to put this:

$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/"; 

// Open the folder
 $dir_handle = @opendir($root . $path) or die("Unable to open $path");
