I have array:
$adm_menu_old = array (
array(
'id' => 1,
'name' => 'Test1',
),
array(
'id' => 3,
'name' => 'Test3',
'childrens' => array(
array(
'id' => 31,
'name' => 'Test31',
),
array(
'id' => 32,
'name' => 'Test32',
'childrens' => array(
array(
'id' => 321,
'name' => 'Test321',
),
),
)
),
array(
'id' => 4,
'name' => 'Test4',
),
);
Say i know id value.
I need get path with all parents of this id.
For example i need get path to this element: id=321
i need get array with key name values:
array('Test3','Test32','Test321')
how should look like recursive function?
Try this function:
function getNames($id, $arr) {
$result = array();
foreach($arr as $key => $val) {
if(is_array($val)) {
if($val["id"] == $id) {
$result[] = $val["name"];
} elseif(!empty($val["childrens"]) && is_array($val["childrens"])) {
$sub_res = getNames($id, $val["childrens"]);
if(count($sub_res) > 0) {
$result[] = $val["name"];
$result = array_merge($result, $sub_res);
}
}
}
}
return $result;
}

I have an array with the following format:
$array = Array(
Array('id' => 77, 'title' => 'title'),
Array('id' => 43, 'title' => 'title2'),
Array('id' => null, 'title' => 'title3'),
Array('id' => null, 'title' => null),
);
This array is populated dynamically, this is just an example. Also, i have a second array with the format:
$searchingArray = Array('43', '5');
The main idea is to search if values from $searchingArray are in $array and if not exists then added. My function is:
function addId($id, $ignoreIfFound=false) {
foreach ($array as $values) {
if ($values['id'] and $values['id'] == $id) {
if (!$ignoreIfFound) {
$array[] = Array('id' => $id, 'title' => 'test5');
break;
}
else{
// do nothing
}
}else{
$array[] = Array('id' => $id, 'title' => 'test5');
break;
}
}
}
foreach ($searchingArray as $id) {
$this->addId($id, true);
}
For given example the result should be:
$array = Array(
Array('id' => 77, 'title' => 'title'),
Array('id' => 43, 'title' => 'title2'),
Array('id' => null, 'title' => 'title3'),
Array('id' => null, 'title' => null),
Array('id' => 5, 'title' => 'test5'),
);
Can you tell me what it is wrong with my code?
This should work for you:
First extract the id column out of your array with array_column(). After this simply loop through your search array and check with in_array() if they id already exists or not. If not simply add it to the array.
$ids = array_column($array, "id");
foreach($searchingArray as $search) {
if(!in_array($search, $ids)) {
$array[] = ["id" => $search, "title" => "title" . $search];
}
}
How to recursively remap children to nodes? I tried writing recursive function, but it only runs one iteration. Array map - http://php.net/manual/en/function.array-map.php would only run for single dimension
I'm using nested sets model https://github.com/etrepat/baum#getting-started Input is generated by dumping all hierarchy
$array = Category::where('name', '=', 'All')->first()->getDescendantsAndSelf()->toHierarchy()->toArray();
/* Input */
$array = array(
'category_id' => 0,
'children' => array(
array(
'category_id' => 1,
'children' => array(
'category_id' => 2,
'children' => array(
'category_id' => 3,
)
)
),
array(
'category_id' => 4,
'children' => array(
'category_id' => 5,
'children' => array(
'category_id' => 6,
)
)
)
)
);
Output should be
/*
$array = array(
'category_id' => 0,
'nodes' => array(
array(
'category_id' => 1,
'nodes' => array(
'category_id' => 2,
'nodes' => array(
'category_id' => 3,
)
)
),
array(
'category_id' => 4,
'nodes' => array(
'category_id' => 5,
'nodes' => array(
'category_id' => 6,
)
)
)
)
);*/
function remap($items){
if(!empty($items['children'])){
$items['nodes'] = $items['children'];
unset($items['children']);
return remap($items['nodes']);
}
else{
return $items;
}
}
print_r(remap($array));
A bit complicated couse , childrens content variates by depth
function remap(array &$items){
if(array_key_exists('children',$items)){
$items['nodes'] = $items['children'];
unset($items['children']);
if(array_key_exists('children',$items['nodes'])){
$items['nodes']['nodes'] = $items['nodes']['children'];
unset($items['nodes']['children']);
}
foreach ($items['nodes'] as &$x) {
if (is_array($x)) {
remap($x);
}
}
}
else{
return $items;
}
}
remap($array);
print_r($array);
This function will change the children keys to nodes.
function remap($items) {
$result = array();
foreach ($items as $key => $value) {
if ($key == 'children') {
$result['nodes'] = remap($value);
} else {
$result[$key] = $value;
}
}
return $result;
}
$new_array = remap($array);
After your comment, though, it seems like it would be easier to create an accessor that maps children to nodes in your Eloquent model and use that in the select that gets your collection.
Let's say i have an array like this:
$array = array(
0 =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
1=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
21 =>
array(
'value' => 'adresa#gmail.com' ,
'name' => 'name1`' ),
23 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
24 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
26 =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
27 =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);
I want to know if exists duplicated value in array with key 'value' I know how to do this if i want a specified value but general no. The result must be an array with no duplicated values(eg:
$array = array(
0 =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
1=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
23 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
26 =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
27 =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);`
Please help me.
This is my try
function has_dupes($array){
$dupe_array = array();
foreach($array as $val){
if(++$dupe_array[$val] > 1){
return true;
}
}
return false;
}
Try this way:
$array = array(
'0' =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
'1'=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
'21' =>
array(
'value' => 'adresa#gmail.com' ,
'name' => 'name1`' ),
'23' =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
'24' =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
'26' =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
'27' =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);
$array = array_map("unserialize", array_unique(array_map("serialize", $array)));
$result = array_unique($array);
print_r($result);
And if you want to store all unique data in one array do it like this:
//declare $array
$unique_array = array();
foreach ($array as $key => $type) {
foreach($type as $vale => $name) {
if ($vale == 'value') {
//echo $name . '<br>';
array_push($unique_array, $name);
}
}
}
$result = array_unique($unique_array);
foreach ($result as $res) {
echo $res . '<br>';
}
Try this
$values = array_map("unserialize", array_unique(array_map("serialize", $array)));
foreach ($values as $key => $value)
{
if ( is_array($value) )
{
$values[$key] = $value;
}
}
print_r($values);
$unique_data = array(); // the result array
$duplicate_data = array();
$seen = array();
foreach ($array as $key => $arr) {
$value = $arr['value'];
if (!isset($seen[$value])) {
$seen[$value] = '';
$unique_data[$key] = $arr;
} else {
$duplicate_data[$key] = $arr; // optional
}
}
unset($seen); // optional in function scope
I have this array:
$all = array(
'meat' => Object(
'name' => 'meat',
'color' => 'red',
'class' => 'food'
),
'chicken' => Object(
'name' => 'chicken',
'color' => 'white',
'class' => 'food'
),
'apple' => Object(
'name' => 'apple',
'color' => 'green',
'class' => 'Fruit'
),
'blueberry' => Object(
'name' => 'blueberry',
'color' => 'blue',
'class' => 'Fruit'
)
);
and i want to Sort it and rebuild it to be like this:
$theright = array(
array(
'class' => 'food',
'menu' => array(
array(
'name' => 'meat',
'color' => 'red',
),
array(
'name' => 'chicken',
'color' => 'white',
)
)
),
array(
'class' => 'Fruit',
'menu' => array(
array(
'name' => 'apple',
'color' => 'green',
),
array(
'name' => 'blueberry',
'color' => 'blue',
)
)
)
);
I tried to Collect all classes in$all array then compare each value with $all array:
$classArray = array();
foreach($all as $key => $value) {
$classArray[$value->class] = array();
}
foreach($classArray as $key => $value) {
$theright[] = array('class' => $key, 'menu' => array());
}
this code get me this array:
$theright = array(
array(
'class' => 'food',
'menu' => array()
),
array(
'class' => 'Fruit',
'menu' => array()
)
);
and i stop here , how to complete it ?
You could just use the class as a key to group them together. Example:
$food = array();
// gather class
foreach($all as $item) {
if(!isset($food[$item->class])) {
$food[$item->class] = array(
'class' => $item->class,
'menu' => array(
array(
'name' => $item->name,
'color' => $item->name,
)
)
);
} else {
$food[$item->class]['menu'][] = array('name' => $item->name,'color' => $item->color,);
}
}
// simple reindex
$food = array_values($food);
There is no need for a second loop. This should do what you want.
$classMap = array();
foreach ($all as $item)
{
// check if class has been created in the class map
if ( ! array_key_exists($classMap, $item['class']))
{
$classMap[$item['class']] = array(
'class' => $item['class'],
'menu' => array()
);
}
$classMap[$item['class']]['menu'][] = array(
'name' => $item['name'],
'color' => $item['color']
);
}
Try with less loop counts (2)
$all = [];
function getSelectClassData(array &$all)
{
$finalArr = [];
while (count($all) > 1) {
$res = [];
$class = array_values($all)[0]->class;
$selectedDataArr = getSelectSimilerMenuData($all, $class);
$res['class'] = $class;
$res['menu'] = array_values($selectedDataArr);
$all = array_diff_key($all,array_flip(array_keys($selectedDataArr)));
$finalArr[] = $res;
}
return $finalArr;
}
function getSelectSimilerMenuData(array $all, $class)
{
return array_filter(
$all,
function ($e) use ($class) {
return $e->class == $class;
}
);
}
print_r(getSelectClassData($all));
I have php array structure like this:
array(
'servicemanagement.scheduler.events.edit' => 'Edit',
'servicemanagement.scheduler.events.delete' => 'Delete',
'servicemanagement.scheduler.events' => 'Events',
'servicemanagement.scheduler' => 'Scheduler',
'servicemanagement.subscribers' => 'Subscribers',
'servicemanagement.subscribers.index' => 'Index',
'servicemanagement' => 'Service management',
);
And I would like to convert is to multidimensional array like:
array(
'servicemanagement' => array(
'id' => 'servicemanagement',
'title' => 'Service Management',
'children' => array(
'scheduler' => array(
'id' => 'servicemanagement.scheduler',
'title' => 'Scheduler',
'children' => array(
'events' => array(
'id' => 'servicemanagement.scheduler.events',
'title' => 'Events',
'children' => array(
'edit' => array(
'id' => 'servicemanagement.scheduler.events.edit',
'title' => 'Edit',
'children' => array(),
),
'delete' => array(
'id' => 'servicemanagement.scheduler.events.delete',
'title' => 'Delete',
'children' => array(),
),
),
),
),
),
'subscribers' => array(
'id' => 'servicemanagement.subscribers',
'title' => 'Subscribers',
'children' => array(
'index' => array(
'id' => 'servicemanagement.subscribers.index',
'title' => 'Index',
)
),
),
),
),
);
I have checked some answers already like this one:
How to set a deep array in PHP
But it seems that i could not manage to clear up the writing on top of the arrays and the last record 'servicemanagement' removes all of the previous records.
The function that is used there is
function setArray(&$array, $keys, $value) {
$keys = explode(".", $keys);
$current = &$array;
foreach($keys as $key) {
$current = &$current[$key];
}
$current = $value;
}
Another function that I have found but it is not doing the expected result is:
function unflatten($array,$prefix = '')
{
$result = array();
foreach($array as $key=>$value) {
if (!empty($prefix)) {
$key = preg_replace('#^'.preg_quote($prefix).'#','',$key);
}
if (strpos($key,'.') !== false) {
parse_str('result['.str_replace('.','][',$key)."]=".$value);
} else {
$result[$key] = $value;
}
}
return $result;
}
It is an option to use recursion to unflatten this array since the end format is the same for all records.
May anyone give me a tip ot this one?
I created an unflatten function for reference here:
https://gist.github.com/Gerst20051/b14c05b72c73b49bc2d306e7c8b86223
$results = [
'id' => 'abc123',
'address.id' => 'def456',
'address.coordinates.lat' => '12.345',
'address.coordinates.lng' => '67.89',
'address.coordinates.geo.accurate' => true,
];
function unflatten($data) {
$output = [];
foreach ($data as $key => $value) {
$parts = explode('.', $key);
$nested = &$output;
while (count($parts) > 1) {
$nested = &$nested[array_shift($parts)];
if (!is_array($nested)) $nested = [];
}
$nested[array_shift($parts)] = $value;
}
return $output;
}
echo json_encode(unflatten($results));
/*
{
"id": "abc123",
"address": {
"id": "def456",
"coordinates": {
"lat": "12.345",
"lng": "67.89",
"geo": {
"accurate": true
}
}
}
}
*/
This was slightly influenced by the following resources:

https://medium.com/#assertchris/dot-notation-3fd3e42edc61
This isn't the cleanest solution but it works as a single function
$your_array = array(
'servicemanagement.scheduler.events.edit' => 'Edit',
'servicemanagement.scheduler.events.delete' => 'Delete',
'servicemanagement.scheduler.events' => 'Events',
'servicemanagement.scheduler' => 'Scheduler',
'servicemanagement.subscribers' => 'Subscribers',
'servicemanagement.subscribers.index' => 'Index',
'servicemanagement' => 'Service management',
);
function expand($array, $level = 0)
{
$result = array();
$next = $level + 1;
foreach($array as $key=>$value) {
$tree = explode('.', $key);
if(isset($tree[$level])) {
if(!isset($tree[$next])) {
$result[$tree[$level]]['id'] = $key;
$result[$tree[$level]]['title'] = $value;
if(!isset($result[$tree[$level]]['children'])) {
$result[$tree[$level]]['children'] = array();
}
} else {
if(isset($result[$tree[$level]]['children'])) {
$result[$tree[$level]]['children'] = array_merge_recursive($result[$tree[$level]]['children'], expand(array($key => $value), $next));
} else {
$result[$tree[$level]]['children'] = expand(array($key => $value), $next);
}
}
}
}
return $result;
}
var_export(expand($your_array));
