I have to compare two folder structure and with reference of source folder I want to delete all the files/folders present in other destination folder which do not exist in reference source folder, how could i do this?
$original = scan_dir_recursive('/var/www/html/copy2');
$mirror = scan_dir_recursive('/var/www/html/copy1');
function scan_dir_recursive($dir) {
$all_paths = array();
$new_paths = scandir($dir);
foreach ($new_paths as $path) {
if ($path == '.' || $path == '..') {
continue;
}
$path = $dir . DIRECTORY_SEPARATOR . $path;
if (is_dir($path)) {
$all_paths = array_merge($all_paths, scan_dir_recursive($path));
} else {
$all_paths[] = $path;
}
}
return $all_paths;
}
foreach($mirror as $mirr)
{
if($mirr != '.' && $mirr != '..')
{
if(!in_array($mirr, $original))
{
unlink($mirr);
// delete the file
}
}
}
The above code shows what i did.. Here My copy1 folder contains extra files than copy2 folders hence i need these extra files to be deleted.
Below given output is are arrays of original Mirror and of difference of both..
Original Array
(
[0] => /var/www/html/copy2/Copy (5) of New Text Document.txt
[1] => /var/www/html/copy2/Copy of New Text Document.txt
)
Mirror Array
(
[0] => /var/www/html/copy1/Copy (2) of New Text Document.txt
[1] => /var/www/html/copy1/Copy (3) of New Text Document.txt
[2] => /var/www/html/copy1/Copy (5) of New Text Document.txt
)
Difference Array
(
[0] => /var/www/html/copy1/Copy (2) of New Text Document.txt
[1] => /var/www/html/copy1/Copy (3) of New Text Document.txt
[2] => /var/www/html/copy1/Copy (5) of New Text Document.txt
)
when i iterate a loop to delete on difference array all files has to be deleted as per displayed output.. how can i rectify this.. the loop for deletion is given below.
$dirs_to_delete = array();
foreach ($diff_path as $path) {
if (is_dir($path)) {
$dirs_to_delete[] = $path;
} else {
unlink($path);
}
}
while ($dir = array_pop($dirs_to_delete)) {
rmdir($dir);
}
