$ar = ['assets/image/man.jpg','assets/image/violin.jpg','assets/image/test.txt'];
 $allowed = ['jpg']; //your image extensions
 $img_ar = [];
 foreach($ar as $img){
     $ext = pathinfo($img,PATHINFO_EXTENSION);
     if(in_array($ext,$allowed)){
         $img_ar[] = $img;
     }

 }
 print_r($img_ar);
