Getting the names of all files in a directory with PHP

For some reason, I keep getting a '1' for the file names with this code:

if (is_dir($log_directory))
{
	if ($handle = opendir($log_directory))
	{
		while($file = readdir($handle) !== FALSE)
		{
			$results_array[] = $file;
		}
		closedir($handle);
	}
}

When I echo each element in $results_array, I get a bunch of '1's, not the name of the file. How do I get the name of the files?

Don't bother with open/readdir and use glob instead:

foreach(glob($log_directory.'/*.*') as $file) {
    ...
}

SPL style:

foreach (new DirectoryIterator(__DIR__) as $file) {
  if ($file->isFile()) {
	  print $file->getFilename() . "\n";
  }
}

Check DirectoryIterator and SplFileInfo classes for the list of available methods that you can use.

As the accepted answer has two important shortfalls, I'm posting the improved answer for those new comers who are looking for a correct answer:

foreach (array_filter(glob('/Path/To/*'), 'is_file') as $file)
{
    // Do something with $file
}

1. Filtering the globe function results with is_file is necessary, because it might return some directories as well.
2. Not all files have a . in their names, so */* pattern sucks in general.

You need to surround $file = readdir($handle) with parentheses.

Here you go:

$log_directory = 'your_dir_name_here';

$results_array = array();

if (is_dir($log_directory))
{
		if ($handle = opendir($log_directory))
		{
                //Notice the parentheses I added:
				while(($file = readdir($handle)) !== FALSE)
				{
						$results_array[] = $file;
				}
				closedir($handle);
		}
}

//Output findings
foreach($results_array as $value)
{
	echo $value . '<br />';
}

Just use glob('*'). Here's Documentation

I have smaller code todo this:

$path = "Pending2Post/";
$files = scandir($path);
foreach ($files as &$value) {
    echo "<a href='http://localhost/".$value."' target='_blank' >".$value."</a><br/><br/>";
}

On some OS you get . .. and .DS_Store, Well we can't use them so let's us hide them.

First start get all information about the files, using scandir()

// Folder where you want to get all files names from
$dir = "uploads/";

/* Hide this */
$hideName = array('.','..','.DS_Store');    

// Sort in ascending order - this is default
$files = scandir($dir);
/* While this to there no more files are */
foreach($files as $filename) {
    if(!in_array($filename, $hideName)){
       /* echo the name of the files */
       echo "$filename<br>";
    }
}

It's due to operator precidence. Try changing it to:

while(($file = readdir($handle)) !== FALSE)
{
    $results_array[] = $file;
}
closedir($handle);

glob() and FilesystemIterator examples:

/* 
 * glob() examples
 */

// get the array of full paths
$result = glob( 'path/*' );

// get the array of file names
$result = array_map( function( $item ) {
	return basename( $item );
}, glob( 'path/*' ) );


/* 
 * FilesystemIterator examples
 */

// get the array of file names by using FilesystemIterator and array_map()
$result = array_map( function( $item ) {
	// $item: SplFileInfo object
	return $item->getFilename();
}, iterator_to_array( new FilesystemIterator( 'path' ), false ) );

// get the array of file names by using FilesystemIterator and iterator_apply() filter
$it = new FilesystemIterator( 'path' );
iterator_apply( 
	$it, 
	function( $item, &$result ) {
		// $item: FilesystemIterator object that points to current element
		$result[] = (string) $item;
        // The function must return TRUE in order to continue iterating
		return true;
	}, 
	array( $it, &$result )
);

You could just try the scandir(Path) function. it is fast and easy to implement

Syntax:

$files = scandir("somePath");

This Function returns a list of file into an Array.

to view the result, you can try

var_dump($files);

Or

foreach($files as $file)
{ 
echo $file."< br>";
} 
 

Another way to list directories and files would be using the RecursiveTreeIterator answered here: https://stackoverflow.com/a/37548504/2032235.

A thorough explanation of RecursiveIteratorIterator and iterators in PHP can be found here: https://stackoverflow.com/a/12236744/2032235

I just use this code:

<?php
    $directory = "Images";
    echo "<div id='images'><p>$directory ...<p>";
    $Files = glob("Images/S*.jpg");
    foreach ($Files as $file) {
        echo "$file<br>";
    }
    echo "</div>";
?>

Use:

if ($handle = opendir("C:\wamp\www\yoursite/download/")) {

    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
            echo "<b>" . preg_replace('/\\.[^.\\s]{3,4}$/', '', $entry) . "</b>";
        }
    }
    closedir($handle);
}

Recursive code to explore all the file contained in a directory ('$path' contains the path of the directory):

function explore_directory($path)
{
    $scans = scandir($path);

    foreach($scans as $scan)
    {
        $new_path = $path.$scan;

        if(is_dir($new_path))
        {
            $new_path = $new_path."/";
            explore_directory($new_path);
        }
        else // A file
        {
            /*
                  Body of code
            */
        }
    }
}

Little something I created for this:

function getFiles($path) {
    if (is_dir($path)) {
        $res = array();
        foreach (array_filter(glob($path ."*"), 'is_file') as $file) {
            array_push($res, str_replace($path, "", $file));                
        }
        return $res;
    }
    return false;
}
