$root1 = $_SERVER['DOCUMENT_ROOT']; 

$directory =
$root1.'/Place4Info/Data/Admin_data/';

$it = new
RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

while($it->valid()) 
{ 
    if(!$it->isDot())

you are calling print_r every time a new file is added. move it after your while loop

$files = array();
while($it->valid()) {
    if(!$it->isDot()) {
        $files = array_merge($files, glob($directory.$it->getSubPath().'/*.jpg'));
    }
    $it->next();
}
print_r($files);

your array is fine, you are simply printing it too often

edit

i assume you want to retrieve all jpg files from your directories, there's a good example in on of the comments on RecursiveDirectoryIterator manual page on php.net:

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('path/to/project/'));
$Regex = new RegexIterator($it, '/^.+\.jpg$/i', RecursiveRegexIterator::GET_MATCH);

quote:

$Regex will contain a single index array for each PHP file.

hey dude i got it it would be like this $i=0; $num=1; while($it->valid() and $i<$num) { if(!$it->isDot()) { $files = glob($directory.$it->getSubPath().'/*.jpg'); print_r($files); $i++; } $it->next(); }
