I have a facebook array and I am trying to echo out the names and ID.
All I have is this array: $friends_list.
When I use this code:
print_r($friends_list);
Then the following comes out below: But how do I loop thru these? Or what if I just wanted to find out how many names there are or just call on one var by id. In short how do I echo out $friends_list which is a multiD array?
Array ( [data] => Array ( [0] => Array ( [name] => Wendy Cukierski [id] => 524320383 ) [1] => Array ( [name] => Leticia Mercado Correa [id] => 537763225 ) [2] => Array ( [name] => Olivia Urbina [id] => 538711855 ) [3] => Array ( [name] => Ruth Albrecht [id] => 541610111 ) [4] => Array ( [name] => Josh Brahm [id] => 577546485 ) [5] => Array ( [name] => Kim Yu [id] => 583515871 ) [6] => Array ( [name] => SisterTracey Dugas [id] => 643567171 ) [97] => Array ( [name] => Mary Martinez [id] => 100004696266210 ) ) [paging] => Array ( [next] => https://graph.facebook.com/1566027944/friends?limit=5000&offset=5000&__after_id=100004696266210 ) )

My arrays result is like this one
Array
(
[0] => Array

[accounts] => Array
(
[0] => Array

[name] => Account WD

(
[name] => Keterangan
[value] =>

[2] => Array
(
[name] => Account ID
[value] =>

)
)
)
It's weird because 2nd array of accounts contains same value as first array.
[0] => Array
(
[name] => Account WD
[value] =>
)
[1] => Array
(
[name] => Keterangan
[value] =>
)
How to prevent this duplicated so the 2nd array of accounts will only show
[0] => Array
(
[name] => Account ID
[value] =>
)
Here's my code
$arr = $arr_pay = array();
foreach($site_payment as $key => $value){
if($value['status'] && $value['ec']>=1000){
$payment_data_cust = unserialize(crypts($value['auto_wd_data'],'d'));
foreach ($payment_data_cust as $ke => $va) {
$arr[] = array("name"=>$va,"value"=>'');
}
$spc[] = array(
"id"=>$value['id'],
"ec"=>$value['ec'],
"accounts"=>$arr
);
}
}
Array of $site_payment contains
[Bank Transfer] => Array
(
[id] => Bank Transfer
[ec] => 1000
[status] => 1
[auto_wd_data] => IjZRcWp1aGtzNmZHbjVPZTlkeStGZVNPaWdPY0lrZ0UyQnd6eFhxQUZoR1VEeU82TzVJZkdMelJrZzJKS3lxXC9yTm5meFBndFRlUDQ9Ig==

[status] => 1
[auto_wd_data] => IkNDek9IY1BtelVEeFFxZEtMc0hvalBkbVBRdENEZEJWakZoaFBJWkNBUk09Ig==
)
I want to show the auto_wd_data of $site_payments with different array so it's became the result, but not duplicating in each array
Please help me to solve the problem
Duplication is due to the $arr is not being reset
$arr_pay = array();
foreach($site_payment as $key => $value){
$arr = array(); // Resetting
if($value['status'] && $value['ec']>=1000){
$payment_data_cust = unserialize(crypts($value['auto_wd_data'],'d'));
foreach ($payment_data_cust as $ke => $va) {
$arr[] = array("name"=>$va,"value"=>'');
}
$spc[] = array(
"id"=>$value['id'],
"ec"=>$value['ec'],
"accounts"=>$arr
);
}

I have three arrays first array include ids and employees name and second array have monthly collection with employee ids and third array have daily collection with employee id and daily collection I want to merge these array with ids and name and dcollection and monthly collection but the desired output is not coming here my first array $ids is
Array

so far what I have tried
$new_array = array();
foreach($ids as $k) {
$q1n = array("id"=>$k->id,"name"=>$k->name);
foreach($q1 as $k1) {
if($k->id==$k1->id){

array_merge($q1n,$mc);
}
}
foreach($q2 as $k1){

$dc = array("dc"=>$k1->dcollecton);
array_merge($q1n,$dc);
}
}
$a = array_merge($q1n,$mc);
$av = array_merge($q1n,$dc);
array_push($new_array,$q1n);
}
but the output is coming as
Array

[dcollection] => 0
)
[3] => Array
(
[id] => 4
[name] => tejpal singh
[mcollection] => 0
[dcollection] => 0
)
)
So I have tried many times but the desired output is not coming . please help me out how to get the desired output.
It seemed like that answer could be modified, or put in a function that you could call multiple times if needed to combine more than two arrays.
There's probably cleaner ways to handle this with array functions like array_merge or array_walk, but this is the general idea of how I might approach it. I haven't tested this, but maybe it's useful.
foreach($first as $key1 => $value){
foreach($second as $key2 => $value2){
// match the ids and check if array key exists on first array
if($value['id'] === $value2['id'] && empty($first[$key2])){
$first[$key][$key2] = $value2;
}
}
}
EDIT: Based on the answer you posted vs the question you asked, are you incrementing the collection numbers or just setting them? In other words why use +=? You should also be able to remove array_merge and array_push.
Below is geared more towards what you're trying to do. I haven't tested this either, but if you run into errors, post your code with the errors returned so that it's easier to debug:
foreach($ids as $k)
{
$thisArray = $newArray[] = array("id"=>$k->id,"name"=>$k->name);
foreach($q1 as $k1)
{
if($k->id == $k1->id && !empty($k1->mcollecton))
{
$thisArray['mc'] = $k1->mcollecton;
}
}
foreach($q2 as $k2)
{
if($k->id == $k2->id && !empty($k2->dcollecton))
{
$thisArray['dc'] = $k2->dcollecton;
}
}
}
// This should have both new collections fields on all array items
print_r($newArray)
I'm trying to unset two specific array positions which contain two values.
My actual code to fill the array.
function get_store_list(){
$data = #file_get_contents('http://www.zwinky.com/xml/clothingList.xml');
$data = #simplexml_load_string($data);
$data = $data->xpath('//stores/store');
foreach($data as $store) {
$storeArray[] = array(
"name" => (string)$store['name'],
"id" => (string)$store['id']
);
}
return $storeArray;
}
$store = get_store_list();
The array looks like the following incase ill echo it out using print_r function:
Array

[id] => 20099506
)
)
Now $store does contain 2 array indexes which I have to delete. Which are the following ids: 21 and 20076231
I've been trying the following already:
Array search code without beeing success. Does anyone have a idea what I could try?
There are a handful different approaches for this simple issue. One of them could be using function array_filter():
/**
* #param array $list the list to process
* #param array $IDsToRemove the IDs of elements to remove from $list
* #return array a subset of $list that does not contain elements having 'id' in $IDsToRemove
*/
function removeFromArray(array $list, array $IDsToRemove)
{
return array_filter(
// Filter the input list...
$list,
// ... using a function...
function (array $item) use ($IDsToRemove) {
// ... that accepts an element if its "id" is not in $IDsToRemove
return ! in_array($item['id'], $IDsToRemove);
}
);
}
// Usage
$filteredStore = removeFromArray($store, array(21, 20076231));
Try this in your loop, this will not include in your array than no need to unset like this:
foreach($data as $store) {
if($store['id'] == '20076231')
continue;
$storeArray[] = array(
"name" => (string)$store['name'],
"id" => (string)$store['id']
);
}
If you need to unset an item from your array after it's been created, take a look at array_map.
First map your array to retrieve the index of each ID.
$map = array_map(function($item){ return $item['id']; }, $store);
Then get the index of your ID from the map (e.g. 21).
$index = array_search(21, $map);
Then remove with array_splice.
array_splice($store, $index, 1);
why not use directly the id in your $storeArray? And as it seems to be integer why do you force it to (string)?
Try this:
function get_store_list(){
$data = #file_get_contents('http://www.zwinky.com/xml/clothingList.xml');
$data = #simplexml_load_string($data);
$data = $data->xpath('//stores/store');
foreach($data as $store) {
$storeArray[(int)$store['id']] = array(
"name" => (string)$store['name']
);
}
return $storeArray;
}
// delete the keys you want
unset ($storeArray[21], $storeArray[20076231]);
// or if you have more ids to delete you can create a deleteArray
$deleteArray = array(2, 20076231);
foreach ($deleteArray as $toDelete){
unset($storeArray($toDelete);
}
One line code is cool but sometimes explicit code is preferable.
function filter_by_id(array $data, $id)
{
foreach ($data as $k => &$v) {
foreach ((array) $id as $i) {
if ($v['id'] === $i) {
$v = null;
}
}
}
// 'array_filter()' produces a new array without the null entries.
// 'array_values()' produces a new array with indexes without gaps.
return array_values(array_filter($data));
}
You can filter by one id at time
$store = filter_by_id($store, 21);
Or you can filter multiple ids at the same time:
$store = filter_by_id($store, [21, 20076231]);
Essentially, I want to use the
$foo = new RecursiveIteratorIterator(new RecursiveArrayIterator($haystack));
Methodology, but instead of returning a flat array for foreach()ing through, keep the structure but only return a single great-grand-child node and it's parent nodes. Is this possible in PHP?
I've been tasked with optimising some of my company's (horrific) codebase. I found a function that recurses through an array, searching for a key. I can't replace this with a simple array_search() or array_key_exists() because the custom function also returns the parent nodes of the matched (found) key, instead of just a true or false.
How can I use RecursiveArrayIterator, RecursiveIteratorIterator or failing that, other built-in functions (i.e. as little custom code as possible) to return a matching node with it's parent tree from a search array? I want to get the fastest function possible, as currently this function spends 8 seconds executing 14 thousand times, hence my requirement to use built-in functions.
My existing attempt (below) is incredibly slow.
function search_in_array($needle, $haystack) {
$path = array();
$it = new RecursiveArrayIterator($haystack);
iterator_apply($it, 'traverse', array($it, $needle, &$path));
return $path;
}
function traverse($it, $needle, &$path) {
while($it->valid()) {
$key = $it->key();
$value = $it->current();
if(strcasecmp($value['id'], $needle) === 0) {
$path[] = $key;
return;
} else if($it->hasChildren()) {
$sub = null;
traverse($it->getChildren(), $needle, &$sub);
if($sub) {
$path[$key] = $sub;
}
}
$it->next();
}
}
Example output for $needle = TVALL would look like this:
Array (
[HOMECINEMA] => Array (
[children] => Array (
[HC-VISION] => Array (
[children] => Array (
[0] => TVALL
)
)
)
)
)
The search array looks something like this (sorry for the vast-ness). There are more than two top-level nodes, but I've truncated it for brevity:

The example below will not necessarily be more performant (in time or memory requirements) but avoids manually recursing through the structure and shows an easier (IMHO) way to build your desired output array.
function search_in_array($needle, $haystack) {
$path = array();
$it = new RecursiveIteratorIterator(
new ParentIterator(new RecursiveArrayIterator($haystack)),
RecursiveIteratorIterator::SELF_FIRST
);
foreach ($it as $key => $value) {
if (array_key_exists('id', $value) && strcasecmp($value['id'], $needle) === 0) {
$path = array($needle);
for ($i = $it->getDepth() - 1; $i >= 0; $i--) {
$path = array($it->getSubIterator($i)->key() => $path);
}
break;
}
}
return $path;
}
Reference
RecursiveIteratorIterator::SELF_FIRST iteration mode - required to see non-"leaf" items
ParentIterator - easy way to filter out the "leaf" items
RecursiveIteratorIterator::getDepth()
RecursiveIteratorIterator::getSubIterator()
Bonus
You could also use the RecursiveIteratorIterator::setMaxDepth() method to limit the recursion to n levels deep, if your array also goes much deeper.
I think this is a tough one! Experts only?
Ok, I have some variables (returned from get_defined_vars):
Array
(
[lead] => Array
(
[2] => fstory
[4] => him
[5] => trtr
[1] => 508b38ee02f502.23680245.png
)
[form] => Array
(
[id] => 3
)
[fields] => Array
(
[0] => Array
(
[adminLabel] => formname
[id] => 2
)
[1] => Array
(
[adminLabel] => hisher
[id] => 4
[2] => Array
(
[adminLabel] => fname
[id] => 5
)
[3] => Array
(
[adminLabel] => sign
[id] => 1
)
)
I need to get the array fields key to be the [fields] [adminLabel] and the value to be the [lead] [#].
So in this example the array would have key=value
formname = fstory
fname = trtr
hisher = his
sign = 508b38ee02f502.23680245.png
Make any sense? Possible?
Try this. It is untested.
$result_values = $array['lead'];
$results = array();
foreach ($array['form']['fields'] as $value) {
if (is_array($value)) {
$results[$value['adminLabel']] = $result_values[$value['id']];
}
}
print_r($results);
