Remove duplicate array data using PHP - php

i want to remove the data from the array when there profile_id duplicate.
this is my array
$response[0]['profile_id'] = 100;
$response[0]['profile_name'] = 'deepu';
$response[0]['address'] = 'deesdvsdvsdvpu';
$response[1]['profile_id'] = 101;
$response[1]['profile_name'] = 'deepu';
$response[1]['address'] = 'deesdvsdvsdvpu';
$response[2]['profile_id'] = 100;
$response[2]['profile_name'] = 'deepu';
$response[2]['address'] = 'deesdvsdvsdvpusdvsdvsdvsdvsdv';
$response[3]['profile_id'] = 102;
$response[3]['profile_name'] = 'desdvsdvepu';
$response[3]['address'] = 'deesdvsdvsdvpusdvsdvsdvsdvsdsdvsdvv';
$input = array_map("unserialize", array_unique(array_map("serialize", $response)));
i want this output
$response[0]['profile_id'] = 100;
$response[0]['profile_name'] = 'deepu';
$response[0]['address'] = 'deesdvsdvsdvpu';
$response[1]['profile_id'] = 101;
$response[1]['profile_name'] = 'deepu';
$response[1]['address'] = 'deesdvsdvsdvpu';
$response[3]['profile_id'] = 102;
$response[3]['profile_name'] = 'desdvsdvepu';
$response[3]['address'] = 'deesdvsdvsdvpusdvsdvsdvsdvsdsdvsdvv';
But I can't get this. If anyone knows about this please help me.

Try the php-function: array_unique
Or manual:
$ids = array();
foreach($response as $key => $entry){
if(in_array($entry['profile_id'], $ids)){
unset($response[$key]);
}else{
$ids[] = $entry['profile_id'];
}
}

$new_arr = array_reduce($response, function($t, $v) {
$profile_id = $v['profile_id'];
if (!isset($t[$profile_id]))
$t[$profile_id] = $v;
return $t;
}, array());
$new_arr = array_values($new_arr); // to get indexes back to 0, 1, 2...

PHP Get duplicate values in array and average second value

I have an array that looks like this:
$ratingsInPosts = array
(
array("1",3),
array("2",5),
array("2",2),
array("5",2),
array("90",1),
array("5",6),
array("2",2),
);
I Want to find duplicate values in the first column and avarage its values from the second column.
So that this("1",3),("2",5),("2",2),("5",2),("90",1),("5",6),("2",2)
ends up like this ("1",3),("2",3),("5",4),("90",1)
Try this tested solution
I got the required Output
$ratingsInPosts = array
(
array("1",3),
array("2",5),
array("2",2),
array("5",2),
array("90",1),
array("5",6),
array("2",2),
);
$arr1 = array_column($ratingsInPosts, 0);
$p = array_count_values($arr1);
foreach($p as $key => $value)
{
$sum = 0;
for($i=0; $i < $value; $i++)
{
$pos = array_search($key, $arr1);
$sum += $ratingsInPosts[$pos][1];
unset($arr1[$pos]);
unset($ratingsInPosts[$pos]);
}
$re[] = array('"'.$key.'"',$sum/$value);
}
print_r($re);
I hope it helps you:
$groups = array();
// in this loop we group values by first column
foreach ($ratingsInPosts as $row) {
$key = $row[0];
if (!isset($groups[$key]) {
$groups[$key] = array();
}
$groups[$key][] = $row[1];
}
$result = array();
foreach ($groups as $key => $value) {
$avg = array_sum($value) / count($value);
$row = array($key, $avg);
$result[] = $row;
}
<?php
header('Content-Type: text/plain');
$ratingsInPosts = array(array("1",3),array("2",5),array("2",2),array("5",2),array("90",1),array("5",6),array("2",2));
$result = array();
$output = array();
foreach($ratingsInPosts as $array){
$result[$array[0]][] = $array[1];
}
foreach($result as $key=>$array){
$output[] = array($key,round(array_sum($array)/count($array)));
}
var_export($output);

$array[$key] = $something creates a new array

I have this php code that's supposed to check how many times a single item is in an array and put the amount in the value of that key.
im asking, why does the $duplicates[$item] += 1; create a new array instead of appending it to the existing array
here is the picture of the output I get.
this is my code:
$itemQuery = $con->prepare("SELECT cart_value FROM active_carts WHERE username=:prodName");
$itemQuery->bindParam(":prodName" , $uname , PDO::PARAM_STR);
$itemQuery->execute();
$itemCount = $itemQuery->fetchAll();
$arrax = $itemCount[0]["cart_value"];
$itemArrX = explode(",", $arrax);
$inQuestion = array();
$duplicates = array();
foreach ($itemArrX as $item) {
if (in_array($item , $inQuestion)) {
$counter = 0;
if (!array_key_exists($item , $duplicates)) {
$duplicates[$item] = $counter;
// doesnt even execute
} else {
echo $duplicates[$item]; // echoes a new array every time
$duplicates[$item] += 1;
}
} else {
array_push($inQuestion, $item);
}
}
It is rather simple, you never created that item in the array.
$data[$key] = $value; //examine that.
try this $duplicates[$item] = $item;
then $duplicates[$item] += 1;
If you're just looking for a count of duplicate values, I like the suggestion about array_count_values() in the comments. That can be run through array_filter() to remove the non-duplicate values.
$itemQuery = $con->prepare("SELECT cart_value FROM active_carts WHERE username=:prodName");
$itemQuery->execute([":prodName"=>$uname]);
$itemArrX = explode(",", $itemQuery->fetchColumn(0));
$itemArrX = ["foo","bar","baz","bar","boo","baz"];
$duplicates = array_filter(array_count_values($itemArrX), function($v){return $v>1;});
$inQuestion = array_unique($itemArrX);
print_r($duplicates);
print_r($inQuestion);
Or here's a condensed version of your code which should work just fine.
$itemQuery = $con->prepare("SELECT cart_value FROM active_carts WHERE username=:prodName");
$itemQuery->execute([":prodName"=>$uname]);
$itemArrX = explode(",", $itemQuery->fetchColumn(0));
$itemArrX = ["foo","bar","baz","bar","boo","baz"];
$duplicates = [];
$inQuestion = [];
foreach ($itemArrX as $item) {
if (in_array($item, $inQuestion)) {
echo $duplicates[$item];
$duplicates[$item]++;
} else {
$duplicates[$item] = 1;
$inQuestion[] = $item;
}
}
print_r($duplicates);
print_r($inQuestion);

Laravel show array json

I want to show data from database: for every id_grup has many lapangan(court)
$groups_resource = Groups::all();
$groups = [];
foreach($groups_resource as $group)
{
$g = new Groups();
$g->id_group = "Group_".$group['id_group'];
$g->name = $group['nama'];
$g->expanded = true;
$g->eventHeight = 25;
$g->children = array();
$groups[] = $g;
$lapangan_resource = Lapangan::with('groups')->orderBy('nama')->get();
foreach($lapangan_resource as $lapangan)
{
$l = new Lapangan();
$l->id_lapangan = $lapangan['id_lapangan'];
$l->name = $lapangan['nama_lapangan'];
$g->children[] = $l;
}
}
return json_encode($groups);
output for above code
[{"id_group":"Group_1","name":"Lapangan Badminton","expanded":true,"eventHeight":25,"children":[]},{"id_group":"Group_2","name":"Lapangan Tenis","expanded":true,"eventHeight":25,"children":[]}]
There is no value for children which might be like this.
[{"id":"group_1","name":"Indoor","expanded":true,"eventHeight":25,"children":[
{"id":"1","name":"Court 1"},
{"id":"2","name":"Court 2"},
{"id":"3","name":"Court 3"},
{"id":"4","name":"Court 4"}]},"id":"group_2","name":"Outdoor","expanded":true,"eventHeight":25,"children":[
{"id":"11","name":"Court 5"},
{"id":"12","name":"Court 6"},
{"id":"13","name":"Court 7"},
{"id":"14","name":"Court 8"}]}]
You are using wrong array braces. You shouldn't first initialize the children property of a group instead of that you can do it like this:
foreach($groups_resource as $group)
{
$g = new Groups();
$g->id_group = "Group_".$group['id_group'];
$g->name = $group['nama'];
$g->expanded = true;
$g->eventHeight = 25;
$l_arr = [];
$lapangan_resource = Lapangan::with('groups')->orderBy('nama')->get();
foreach($lapangan_resource as $lapangan)
{
$l = new Lapangan();
$l->id_lapangan = $lapangan['id_lapangan'];
$l->name = $lapangan['nama_lapangan'];
$l_arr[] = $l;
}
$g->children = $l_arr;
$groups[] = $g;
}
return json_encode($groups);
Hope this helps!

array_multisort how to mount with foreach

I need to mount an array_multisort with the values from one array.
I tryied to mount a string concated and call on the array_multidimensional like here:
function ordenar_matriz_ultima_posicion_por_distancia($matriz_up,$m_vehiculo_distancias){
$total_vehiculos=count($matriz_up[id_vehiculo]);
//resetear las keys de vehiculos para coger bien los kms y asignarlos
$a_vehiculo_distancia = array_values($m_vehiculo_distancias);
$ordenar = array();
foreach ($a_vehiculo_distancia as $key) {
$ordenar[] = $key;
}
sort($m_vehiculo_distancias);
$string= "";
$ultim_key = end(array_keys($matriz_up));
foreach ($matriz_up as $key => $valor) {
if ($key != $ultim_key) $string.= $matriz_up[$key].',';
else $string.= $matriz_up[$key];
$aaa = '$matriz_up[$key]';
}
echo $string;
echo "<br>";
array_multisort($ordenar, SORT_ASC, $string);
for($i=0;$i<$total_vehiculos;$i++){
$matriz_up['cercanos'][$i] = $m_vehiculo_distancias[$i];
echo $matriz_up['id_vehiculo'][$i]."<br>";
echo $matriz_up['fecha_gps'][$i]."<br>";
echo $matriz_up['id_tipo_posicion'][$i]."<br>";
echo $matriz_up['cercanos'][$i]."<br>";
echo $matriz_up['vaina'][$i]."<br>";
echo "------------<br>";
}
return $matriz_up;
}
$matriz_up['id_vehiculo'][0] = 9;
$matriz_up['fecha_gps'][0] = '2014';
$matriz_up['id_tipo_posicion'][0] = 11111;
$matriz_up['cercanos'][0] = 0;
$matriz_up['vaina'][0] = 12345;
$matriz_up['id_vehiculo'][1] = 3;
$matriz_up['fecha_gps'][1] = '2015';
$matriz_up['id_tipo_posicion'][1] = 22222;
$matriz_up['cercanos'][1] = 0;
$matriz_up['vaina'][1] = 5555;
$matriz_up['id_vehiculo'][2] = 1;
$matriz_up['fecha_gps'][2] = '2016';
$matriz_up['id_tipo_posicion'][2] = 33333;
$matriz_up['cercanos'][2] = 0;
$matriz_up['vaina'][2] = 988;

$matriz_up['cercanos'][3] = 0;
$matriz_up['vaina'][3] = 777;
$m_vehiculo_distancias[9] = 345;
$m_vehiculo_distancias[3] = 712;
$m_vehiculo_distancias[1] = 10;
$m_vehiculo_distancias[4] = 35;
ordenar_matriz_ultima_posicion_por_distancia($matriz_up,$m_vehiculo_distancias);
With this array_multisort works, but i need to take all the key without put manually..
array_multisort($ordenar, SORT_ASC, $matriz_up['id_vehiculo'], $matriz_up['fecha_gps'], $matriz_up['id_tipo_posicion'], $matriz_up['vaina'] );
Try this code:
<?php
$matriz_up = $m_vehiculo_distancias = array();
$matriz_up['id_vehiculo'][0] = 9;
$matriz_up['fecha_gps'][0] = '2014';
$matriz_up['id_tipo_posicion'][0] = 11111;
$matriz_up['cercanos'][0] = 0;
$matriz_up['vaina'][0] = 12345;
$matriz_up['id_vehiculo'][1] = 3;
$matriz_up['fecha_gps'][1] = '2015';
$matriz_up['id_tipo_posicion'][1] = 22222;
$matriz_up['cercanos'][1] = 0;
$matriz_up['vaina'][1] = 5555;

PHP: Sort multidimensional array, but keep its substructure

I have a multidimensional arrays with the following structure:
$arr[0][0] = 1.24;
$arr[0][1] = 5.21;
$arr[0][2] = 2.72;
$arr[0][3] = 1.89;
$arr[0][4] = 4.62;
$arr[1][0] = 3.45;
$arr[1][1] = 5.61;
$arr[1][2] = 2.62;
$arr[1][3] = 1.12;
$arr[1][4] = 1.35;
This array should get sorted while keeping the suborder of $arr[0] and $arr[1], so the result looks like this:
$arr[0][0] = 1.24;
$arr[1][0] = 3.45;
$arr[0][1] = 5.21;
$arr[0][2] = 2.72;
$arr[0][3] = 1.89;
$arr[0][4] = 4.62;
$arr[1][2] = 2.62;
$arr[1][3] = 1.12;
$arr[1][4] = 1.35;
$arr[1][1] = 5.61;
I do not care in which form the result get saved, but I need both keys and the value. Hope you understand and can help me.
How about looping the outer array and sorting the inner?
foreach ($arr as $id => $data) {
sort($data);
$arr[$id] = $data;
}
$arr[0][0] = 1.24;
$arr[0][1] = 5.21;
$arr[0][2] = 2.72;
$arr[0][3] = 1.89;
$arr[0][4] = 4.62;
$arr[1][0] = 3.45;
$arr[1][1] = 5.61;
$arr[1][2] = 2.62;
$arr[1][3] = 1.12;
$arr[1][4] = 1.35;
$size = count($arr);
$outArr= array();
foreach($arr[0] as $key =>$value)
{
$resArr = array();
for($i = 0 ; $i< $size ; $i++)
{
$resArr[] = $arr[$i][$key] ;
}
sort($resArr);
$outArr[$key] = $resArr;
}
echo "<pre>";
print_r($outArr);
Check if this is a closer solution.
