How to put all file names in php array

Question

How do I put every file name on the root directory and and all the file names in each sub folder into an array in php?

What about reading the documentation? What about googling for a suggestion? This forum is not for having someone else do your homework. First try yourself to solve the problem, and if you really are stuck, then is the time to write a question here. A good question, containing teh attempt you did until then, code, problem description and all. — arkascha

Use scandir() and you'll find a recursive function for sub-directories as well as tons of other examples to achieve what you want.

I have always preferred DirectoryIterator and RecursiveDirectoryIterator.

Here is an example:

function drawArray(DirectoryIterator $directory)
{
    $result=array();
    foreach($directory as $object)
    {
        if($object->isDir()&&!$object->isDot())
        {
            $result[$object->getFilename()]=drawArray(new DirectoryIterator($object->getPathname()));
        }
        else if($object->isFile())
        {
            $result[]=$object->getFilename();
        }
    }
    return $result;
}
$array=drawArray(new DirectoryIterator('/path'));
print_r($array);

This is a great suggestion using SPL. Recommended!

Have a look at glob() [and give condolence to your RAM by the way if you really want to skim all your files].

This is how I do it.

/**
    Recursively returns all the items in the given directory alphabetically as keys in an array, optionally in descending order.
    If a key has an array value it's a directory and its items are in the array in the same manner.
*/
function scandir_tree($directory_name, $sort_order = SCANDIR_SORT_ASCENDING, $_recursed = false)
    {
    if (!$_recursed || is_dir($directory_name))
        {
        $items = array_diff(scandir($directory_name, (int) $sort_order), ['.', '..']);
        $tree = [];
        foreach ($items as $item)
            {
            $tree[$item] = scandir_tree($directory_name . $item, $sort_order, true);
            }
        return $tree;
        }
    return $directory_name;
    }

Try this:

$ar=array();
$g=scandir('..');
foreach($g as $x)
{
    if(is_dir($x))$ar[$x]=scandir($x);
    else $ar[]=$x;
}
print_r($ar);
