PHP Working with Directories

Handle a directory there are several functions in PHP language.
i. mkdir()
ii. opendir()
iii. readdir()
iv. scandir()
v. rmdir()
vi. closedir()

i. Create Directory
Want to create a new folder using PHP then use mkdir(). Only one argument is required the folder name or folder location where want to create the folder.

Example

<?php
    mkdir('New Folder');
?>

<?php

mkdir('New Folder');

ii. Open Directory
Using opendir() function can open a folder.Only one argument is required the folder path that is to be opened.

Example

<?php
    opendir('C:\xampp\htdocs\MVT\Array\New Folder');
    echo'Directory open';
?>

<?php

opendir('C:\xampp\htdocs\MVT\Array\New Folder');

echo'Directory open';

iii. Read Directory
readdir() is used to read any folder content. Return the all files and sub directory list of the specified folder (what want to read). One argument is required the folder path.
Example

<?php
    $handle = opendir('C:\xampp\htdocs\MVT\Array');
    while (false !== ($files = readdir($handle))) {
        echo "$files<BR>";
    }
?>

<?php

$handle = opendir('C:\xampp\htdocs\MVT\Array');

while (false !== ($files = readdir($handle))) {

echo "$files<BR>";

}

Output

    .
    ..
    3wishes.txt
    array.php
    copy-flower.jpg
    file_create.php
    flower.jpg
    index1.php
    menu.php
    New folder
    new text file.txt
    newfile.txt
    picture.jpg

iv.Scan Directory
sacndir() is same as readdir() but there are small difference. sacndir() return the all files and sub folder name as an array. One argument is required the folder path. No need to open folder in this case.

Example

<?php
    $folderlocation = 'C:\xampp\htdocs\MVT\Array';
    $allfiles = scandir($folderlocation);
    echo "<PRE>";
    print_r($allfiles);
    echo "

<?php

$folderlocation = 'C:\xampp\htdocs\MVT\Array';

$allfiles = scandir($folderlocation);

echo "<PRE>";

print_r($allfiles);

echo "

”;
?>

Output

Array
(
    [0] => .
    [1] => ..
    [2] => 3wishes.txt
    [3] =>New folder
    [4] =>array.php
    [5] => copy-flower.jpg
    [6] =>file_create.php
    [7] => flower.jpg
    [8] => index1.php
    [9] =>menu.php
    [10] => new text file.txt
    [11] => newfile.txt
    [12] => picture.jpg
)
