PHP code example for reading directory list and file list

/**
 * getDir() goes to the folder list
* getFile() goes to the file list under the corresponding folder
* The difference between the two is to determine whether there are files with a "." suffix, everything else is the same
* edit bbs.it-home .org
*/
//Get the file directory list, this method returns an array
function getDir($dir ) {
 $dirArray[]=NULL;
 if (false != ($handle = opendir ( $dir ))) {
 $i=0;
 while ( false !== ($file = readdir ( $handle ) ) ) {
 //Remove "".", ".." and files with ".xxx" suffix
 if ($file != "." && $file != ".."&&!strpos($file ,".")) {
 $dirArray[$i]=$file;
 $i++;
 }
 }
 //Close the handle
 closedir ( $handle );
 }
 return $dirArray;
}
//Get the file list
function getFile($dir) {
 $fileArray[]=NULL;
 if (false != ($handle = opendir ( $dir ))) {
 $i= 0;
 while ( false !== ($file = readdir ( $handle )) ) {
 //Remove "".", ".." and files with ".xxx" suffix
 if ($file != "." && $file != ".."&&strpos($file,".")) {
 $fileArray[$i]="./imageroot/current/".$file;
 if($i== 100){
 break;
 }
 $i++;
 }
 }
 //Close the handle
 closedir ( $handle );
 }
 return $fileArray;
}
//Call Method getDir("./dir")...can be an absolute path or a relative path
