PHP Removing duplicate objects from array

Question

I\'ve tried all sorts of PHP logic and PHP\'s built in functions to remove duplicate values but it is not working no errors shows up but all my JQuery and CSS doesn\'t work

Answer 1

You can make it unique for any field (key) like id, name or num

function unique_multidimensional_array($array, $key) {
    $temp_array = array();
    $i = 0;
    $key_array = array();

    foreach($array as $val) {
        if (!in_array($val[$key], $key_array)) {
            $key_array[$i] = $val[$key];
            $temp_array[$i] = $val;
        }
        $i++;
    }
    return $temp_array;
}

Answer 2

try the following code

function my_array_unique($array, $keep_key_assoc = false){
    $duplicate_keys = array();
    $tmp = array();       

    foreach ($array as $key => $val){
        // convert objects to arrays, in_array() does not support objects
        if (is_object($val))
            $val = (array)$val;

        if (!in_array($val, $tmp))
            $tmp[] = $val;
        else
            $duplicate_keys[] = $key;
    }

    foreach ($duplicate_keys as $key)
        unset($array[$key]);

    return $keep_key_assoc ? $array : array_values($array);
}
