any or guidance helpful.

try this, give result expecting:

$typearr = array(); foreach($result $a){     $typearr[$a['chanct_name']][] = array(         'name'=>$a['con_name'],         'image'=>$a['con_image']     ); }  $jsonarray = array(); foreach($typearr $type=>$contents){     $jsonarray['channelscategories'][] = array(         'name'=>$type,         'contents'=>$contents     ); }  echo json_encode($jsonarray);
