PHP - Copy the entire contents of a directory to another directory

By IncludeHelp Last updated : January 10, 2024

Problem statement

Write a PHP program to copy the entire contents of a directory to another directory.

Copying the entire contents of a directory to another directory

Write a recursive function.
Open the source directory using the opendir() function.
Make the target directory (if does not exists) using the @mkdir() function.
Loop through the files in the source directory, and read the directory using the readdir() function.
Check the conditions for file existence inside the loop.
If files exist, copy files from source path to target path.
Call the function recursively.

PHP program to copy the entire contents of a directory to another directory

Here, are copying all files from the source directory which is (E:/samples/collection) to another (E:/php_programs/new).

<?php
function copy_all_files($source_dir, $target_dir)
{
    // opening the source directory
    $dir_obj = opendir($source_dir);

    // creating targeted directory if it does not exist
    @mkdir($target_dir);

    while ($file = readdir($dir_obj)) {
        if ($file != "." && $file != "..") {
            if (is_dir($source_dir . "/" . $file)) {
                // Recursive call
                copy_all_files(
                    $source_dir . "/" . $file,
                    $target_dir . "/" . $file
                );
            } else {
                copy($source_dir . "/" . $file, $target_dir . "/" . $file);
            }
        }
    }
    closedir($dir_obj);
}

// Main code
$source_dir = "E:/samples/collection";
$target_dir = "E:/php_programs/new";

copy_all_files($source_dir, $target_dir);
?>
