// get all the files, directory names in a directory (not including subdirectories under the file, directory name) 
    $ Handler = opendir ( $ dir );
     the while (( $ filename = readdir ( $ Handler !)) == false ) { / / Always use == prevent similar filename "0" and the like occurs directory! 
        IF ( $ filename = &&! "." $ filename = ".."! {)
                 $ files [] = $ filename ; 
           } 
       } 
    } 
    closedir ( $ Handler ); 
     
// print all file names 
foreach ( $ filens as $value) {
    echo $value."<br />";

function get_allfiles($path,&$files) {
    if(is_dir($path)){
        $dp = dir($path);
        while ($file = $dp ->read()){
            if($file !="." && $file !=".."){
                get_allfiles($path."/".$file, $files);
            }
        }
        $dp ->close();
    }
    if(is_file($path)){
        $files[] =  $path;
    }
}
   
function get_filenamesbydir($dir){
    $files =  array();
    get_allfiles($dir,$files);
    return $files;
}
   
$filenames = get_filenamesbydir("static/image/");
//打印所有文件名，包括路径
foreach ($filenames as $value) {
    echo $value."<br />";
