Your end result in $jsonrs is a bit unusual, I (am assuming) that you want to JSON encode the list of images, if so then use $items to keep a list of each image and then json_encode() this list after the loop...
foreach ($manga_name[1] as $key => $manganm) {
$filename = basename($manganm);
$imag_num = str_replace('t.jpg','',$filename);
$items[$imag_num] = $filename;
}
echo json_encode($items);
will give you
{"1":"1t.jpg","2":"2t.jpg","3":"3t.jpg","4":"4t.jpg"}
