Example of php traversing all files and subfolders under a folder_PHP tutorial

Traverse the directory and store the results in an array. Supports php4 and above. After php5, the scandir() function can be used to replace the while loop.

Copy code The code is as follows:

/**
* @param string $dir
* @return array
*/
function my_scandir($dir)
{
$files = array();
if ( $handle = opendir($dir) ) {
while ( ($file = readdir($ handle)) !== false )
{
if ( $file != ".." && $file != "." )
{
if ( is_dir($dir . "/ " . $file) )
{
$files[$file] = my_scandir($dir . "/" . $file);
}
else
{
$files [] = $file;
}
}
}
closedir($handle);
return $files;
}
}

function my_scandir1($dir)
{
$files = array();
$dir_list = scandir($dir);
foreach($dir_list as $file)
{
if ( $file != ".." && $file != "." )
{
if ( is_dir($dir . "/" . $file) )
{
$files[$file] = my_scandir1($dir . "/" . $file);
}
else
{
$files[] = $file;
}
}
}

return $files;
}

$result = my_scandir('./');
$result = my_scandir1('./');
?>

Another implementation method

Copy code The code is as follows:

function fetchDir($dir) {
        foreach (glob($dir.'*') as $file) {
      echo $file,"n"; }
                                                                                                                                                           
You can also replace '*' with DIRECTORY_SEPARATOR.'*' and 'n' with PHP_EOL, so that it can be cross-platform.
