Categories of products related to drinking water hygiene and safety. Use PHP to implement recursive loops for each directory.

The principle of the function is very simple, mainly using recursive calls.

Copy code The code is as follows:

function file_list($path){
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle)) )) {
if ($file != "." && $file != "..") {
if (is_dir($path."/".$file)) {
echo $path.": ". $file."
";//Remove this line to display all non-directory files
file_list($path."/".$file);
} else {
echo $path.": ". $file."
";
}
}
}
}
}

This function can also continue to make some improvements and add some folder or file icons, so that it can be made more powerful This is a function. Friends who are interested can expand it.
