cause no one trying to answer and just vote down to this question
so I do some little trick for this in my .php files

<!-- read json -->
<?php
$getjsonstring = file_get_contents('json.txt');
$arrayforcheck = array(); // hold value for check with in_array
$arraytouse = array(); // result array will be here
$arrayredundant = array(); // all redudant store here
$arraysimiliar = array(); // range less than 10m store here

// here is the loop
for ($a=0; $a < count($arrjson); $a++) {
$lat = $arrjson[$a]->latitude;
$lon = $arrjson[$a]->longitude;
$referid = $arrjson[$a]->referid;
$categoryid = $arrjson[$a]->categoryid;
$imagename = $imageurl.$arrjson[$a]->image_name;
$upload_date = date("d M Y H:i:s", strtotime($arrjson[$a]->upload_date));
$description = $arrjson[$a]->description;
$address = $arrjson[$a]->address;
$username = $arrjson[$a]->username;

// give condition push to redundant on identic
if (in_array($lat.'|'.$lon, $arrayforcheck)) {
$arrayredundant[$a] = array($referid, $categoryid, $lat, $lon, array($imagename), $upload_date, $description, $address, $username, $message);
}
// loop for check with $arrayforcheck
else {
$passvalue[$a] = array();
for ($i=0; $i < count($arrayforcheck); $i++) { 
$splitforcheck = explode('|', $arrayforcheck[$i]);
$latcheck = $splitforcheck[0];
$loncheck = $splitforcheck[1];
$diflat = abs(round((abs($lat) - abs($latcheck)), 5));
$diflon = abs(round((abs($lon) - abs($loncheck)), 5));
if ($diflat > 0.0001 || $diflon > 0.0001) {
array_push($passvalue[$a], $diflat.'|'.$diflon);
}
// if all check with $arraycheck is pass
if (count($passvalue[$a]) == count($arrayforcheck)) {
$arraytouse[$a] = array($referid, $categoryid, $lat, $lon, array($imagename), $upload_date, $description, $address, $username, $message);
array_push($arrayforcheck, $lat.'|'.$lon);
}
else {
$arraysimiliar[$a] = array($referid, $categoryid, $lat, $lon, array($imagename), $upload_date, $description, $address, $username, $message);
array_push($arrayforcheck, $lat.'|'.$lon);
}
}
}

now your marker is store in $arraytouse
just fetch as any output form as you wanted...
hopes this help others
