How to remove Duplicate Array element by specifying index like article_id That means there would no other element having same article id in array .
This is what i am getting
$data["related_post"] =$CI->Article_model->get_related_post($SearchTag);
and
echo "<pre>"; print_r($data["related_post"]); echo "</pre>";
Output:
Array

function get_keys_for_duplicate_values($my_arr, $clean = false) {
if ($clean) {
return array_unique($my_arr);
}
$dups = $new_arr = array();
foreach ($my_arr as $key => $val) {
if (!isset($new_arr[$val])) {
$new_arr[$val] = $key;
} else {
if (isset($dups[$val])) {
$dups[$val][] = $key;
} else {
$dups[$val] = array($key);
// Comment out the previous line, and uncomment the following line to
// include the initial key in the dups array.
// $dups[$val] = array($new_arr[$val], $key);
}
}
}
return $dups;
}
