PHP directory operation example code_PHP tutorial

$dirname = "./final/factapplication";

function listdir($dirname) {
$ds = opendir($dirname);
while (false !== ($file = readdir($ds))) {
$path = $ dirname.'/'.$file;
             if ($file != '.' && $file != '..') {
                                                                                                                        path);
} else {
}
closedir($ds);
}
listdir($dirname);

mkdir($dstdir);
$ds = opendir($srcdir);

while (false !== ($file = readdir($ds))) {
$path = $srcdir."/".$file;
$dstpath = $dstdir."/". $file;

if (is_dir($path)) {
copydir($path, $dstpath);
                                                                                                                                                      >      closedir($ds);

}

copydir($srcdir, $dstdir);



Core: copy function.

The code is as follows:

$dirname = 'a';

function deldir($dirname) {
$ds = opendir($dirname);

while (false !== ($file = readdir($ds))) {
$path = $dirname.'/'.$file;
if($file != '.' && $file != '..') {
                                                                                                                                                                                                  
                                                                                                                                       🎜>


Core: Note that unlink deletes the file with path.




Copy code

The code is as follows:

}

echo dirsize($dirname);


Core: Understand recursive functions by determining where $tot returns.
