How to get if data exist in array in php - php

I am making laravel project.
I need to get data list from request.
So should get this data if data exist next.
I used below code...
for($i = 0; $i < count($request->post('pickup_location')); $i++)
{
if($request->post('meeting_ids')[$i])
{
$meeting_profile = MeetingPoint::findOrFail($request->post('meeting_ids')[$i]);
$meeting_data = array(
'pickup_location' => $request->post('pickup_location')[$i],
'pickup_type' => $request->post('pickup_type')[$i],
'pickup_time' => $request->post('pickup_time')[$i],
);
$meeting_profile->fill($meeting_data);
$meeting_profile->save();
} else {
$meeting_profile = new MeetingPoint;
$meeting_data = array(
'holiday_id' => $profile->id,
'pickup_location' => $request->post('pickup_location')[$i],
'pickup_type' => $request->post('pickup_type')[$i],
'pickup_time' => $request->post('pickup_time')[$i],
);
$meeting_profile->fill($meeting_data);
$meeting_profile->save();
}
}
But there is this error:
How can I get next data list with that logic?

Please do like below...
for($i = 0; $i < count($request->post('pickup_location')); $i++)
{
if(isset($request->post('meeting_ids')[$i]))
{
$meeting_profile = MeetingPoint::findOrFail($request->post('meeting_ids')[$i]);
$meeting_data = array(
'pickup_location' => isset($request->post('pickup_location')[$i]) ? $request->post('pickup_location')[$i] : null,
'pickup_type' => isset($request->post('pickup_type')[$i]) ? $request->post('pickup_type')[$i] : null,
'pickup_time' => isset($request->post('pickup_time')[$i]) ? $request->post('pickup_time')[$i] : null,
);
$meeting_profile->fill($meeting_data);
$meeting_profile->save();
} else {
$meeting_profile = new MeetingPoint;
$meeting_data = array(
'holiday_id' => $profile->id,
'pickup_location' => isset($request->post('pickup_location')[$i]) ? $request->post('pickup_location')[$i] : null,
'pickup_type' => isset($request->post('pickup_type')[$i]) ? $request->post('pickup_type')[$i] : null,
'pickup_time' => isset($request->post('pickup_time')[$i]) ? $request->post('pickup_time')[$i] : null,
);
$meeting_profile->fill($meeting_data);
$meeting_profile->save();
}
}

You could use Arr Helper function to more clean and organized code.
$values = $request->all();
for($i = 0; $i < count(Arr::get($values, 'pickup_location')); $i++)
{
if($id = Arr::get($values, "meeting_ids.{$i}"))
{
$meeting_profile = MeetingPoint::findOrFail($id);
$meeting_data = array(
'pickup_location' => Arr::get($values, "pickup_location.{$i}"),
'pickup_type' => Arr::get($values, "pickup_type.{$i}"),
'pickup_time' => Arr::get($values, "pickup_time.{$i}"),
);
$meeting_profile->fill($meeting_data);
$meeting_profile->save();
} else {
...
}
}

Please do like below
<?php
$array1 = [
"Orange" => 100,
"Apple" => 200,
"Banana" => 300,
"Cherry" => 400
];
if ( array_key_exists("Banana", $array1) )
echo "Array Key exists...";
else
echo "Array Key does not exist...";
?>

which algorithm php to create a secret Santa program

I'm trying to make a draw for a secret Santa.
I collect in a table the information of the person and the name of the person on whom it should not fall (to avoid couples).
However during my PHP loop I can't take into account my exclusions
foreach ($supplier as $sup){
$exclude = $sup['blacklist'];
$data = $recipient;
$temp = array_diff($data[], array($exclude));
echo $temp[rand(0, sizeOf($temp))];
foreach ($recipient as $key=>$recip){
if ($sup['surname'] !== $recip['surname']){
$result[] = ['recipient' => $recip, 'supplier' => $sup];
unset($recipient[$key]);
}
}
}
How can I take into account this blacklist please?
shuffle($supplier);
shuffle($recipient);
// dump($supplier, $recipient);
$result = [];
foreach ($supplier as $sup){
$assign = false;
dump($sup);
foreach ($recipient as $key=>$recip){
dump($recip['surname']);
if ($sup['surname'] !== $recip['surname'] && $sup['blacklist'] !== $recip['surname'] && $sup['surname'] !== $recip['blacklist']){
$result[] = ['recipient' => $recip, 'supplier' => $sup];
dump($sup['surname']);
unset($recipient[$key]);
$assign = true;
}
if ($assign === true){
break;
}
}
}
return $result;
}
this is my code with shuffle
Your solution is fine, but with that nested loop it's going to start behaving poorly as the list of participants grows. You can accomplish the task with a single array and two linear passes over it:
$people = [
[ 'name' => 'alice', 'blacklist' => ['bob'] ],
[ 'name' => 'bob', 'blacklist' => ['alice'] ],
[ 'name' => 'carl', 'blacklist' => ['david'] ],
[ 'name' => 'david', 'blacklist' => ['carl'] ],
[ 'name' => 'elise', 'blacklist' => ['frank'] ],
[ 'name' => 'frank', 'blacklist' => ['elise'] ],
[ 'name' => 'georg', 'blacklist' => ['herb'] ],
[ 'name' => 'herb', 'blacklist' => ['george'] ]
];
function wrap_index($count, $index) {
$cur = $index;
if( $index == 0 ) {
$prev = $count - 1;
$next = $index + 1;
} else if( $index == $count - 1) {
$prev = $index - 1;
$next = 0;
} else {
$prev = $index - 1;
$next = $index + 1;
}
return [$prev, $cur, $next];
}
function array_swap(&$array, $a, $b) {
$tmp = $array[$a];
$array[$a] = $array[$b];
$array[$b] = $tmp;
}
function santify($people) {
shuffle($people);
$count = count($people);
for( $i=0; $i<$count; ++$i ) {
list($prev, $cur, $next) = wrap_index($count, $i);
if( in_array($people[$cur]['name'], $people[$next]['blacklist']) ) {
printf("%s in blacklist for %s\n", $people[$cur]['name'], $people[$next]['name']);
array_swap($people, $cur, $prev);
}
}
$pairs = [];
for( $i=0; $i<$count; ++$i ) {
list($prev, $cur, $next) = wrap_index($count, $i);
$pairs[] = [ $people[$cur]['name'], $people[$next]['name'] ];
}
return $pairs;
}
foreach( santify($people) as $pair ) {
printf("%s\n", json_encode($pair));
}
Output:
david in blacklist for carl
elise in blacklist for frank
["david","georg"]
["georg","carl"]
["carl","bob"]
["bob","herb"]
["herb","elise"]
["elise","alice"]
["alice","frank"]
["frank","david"]
There is a caveat to this approach, though. It will only work with strict 1:1 blacklist arrangements. Once there is a love triangle [or quardrangle or above] or any polyamory, neither of our solutions is equipped for these extra dimensions.

Parsing returns an empty value

I make a parser of items from DotA 2 user inventory in the Steam service. Every time I try to parse user data, I get an empty value:
{"success":true,"items":[]}, but there are items in my Steam inventory.
My function to parse items:
public function loadMyInventory() {
if(Auth::guest()) return ['success' => false];
$prices = json_decode(Storage::get('prices.txt'), true);
$response = json_decode(file_get_contents('https://steamcommunity.com/inventory/'.$this->user->steamid64.'/570/2?l=russian&count=5000'), true);
if(time() < (Session::get('InvUPD') + 5)) {
return [
'success' => false,
'msg' => 'Error, repeat in '.(Session::get('InvUPD') - time() + 5).' сек.',
'status' => 'error'
];
}
//return $response;
$inventory = [];
foreach($response['assets'] as $item) {
$find = 0;
foreach($response['descriptions'] as $descriptions) {
if($find == 0) {
if(($descriptions['classid'] == $item['classid']) && ($descriptions['instanceid'] == $item['instanceid'])) {
$find++;
# If we find the price of an item, then move on.
if(isset($prices[$descriptions['market_hash_name']])) {
# Search data
$price = $prices[$descriptions['market_hash_name']]*$this->config->curs;
$class = false;
$text = false;
if($price <= $this->config->min_dep_sum) {
$price = 0;
$text = 'Cheap';
$class = 'minPrice';
}
if(($descriptions['tradable'] == 0) || ($descriptions['marketable'] == 0)) {
$price = 0;
$class = 'minPrice';
$text = 'Not tradable';
}
# Adding to Array
$inventory[] = [
'name' => $descriptions['market_name'],
'price' => floor($price),
'color' => $this->getRarity($descriptions['tags']),
'tradable' => $descriptions['tradable'],
'class' => $class,
'text' => $text,
'classid' => $item['classid'],
'assetid' => $item['assetid'],
'instanceid' => $item['instanceid']
];
}
}
}
}
}
Session::put('InvUPD', (time() + 5));
return [
'success' => true,
'items' => $inventory
];
}
But should return approximately the following value:
{"success":true,"items":[{"classid":"2274725521","instanceid":"57949762","assetid":"18235196074","market_hash_name":"Full-Bore Bonanza","price":26}]}
Where my mistake?
First of all, you are iterating on descriptions for every assets, which is assets*descriptions iteration, it's quite a lot, but you can optimize this.
let's loop once for descriptions and assign classid and instanceid as object key.
$assets = $response["assets"];
$descriptions = $response["descriptions"];
$newDescriptions=[];
foreach($descriptions as $d){
$newDescriptions[$d["classid"]][$d["instanceid"]] = $d;
}
this will give as the ability to not loop over description each time, we can access the description of certain asset directly $newDescriptions[$classid][$instanceid]]
foreach($assets as $a){
if(isset($newDescriptions[$a["classid"]]) && isset($newDescriptions[$a["classid"]][$a["instanceid"]])){
$assetDescription = $newDescriptions[$a["classid"]][$a["instanceid"]];
$inventory = [];
if(isset($prices[$assetDescription["market_hash_name"]])){
$price = $prices[$assetDescription['market_hash_name']]["price"]*$this->config->curs;
$class = false;
$text = false;
if($price <= $this->config->min_dep_sum) {
$price = 0;
$text = 'Cheap';
$class = 'minPrice';
}
if(($assetDescription['tradable'] == 0) || ($assetDescription['marketable'] == 0)) {
$price = 0;
$class = 'minPrice';
$text = 'Not tradable';
}
$inventory["priceFound"][] = [
'name' => $assetDescription['market_name'],
'price' => floor($price),
'color' => $this->getRarity($assetDescription['tags']),
'tradable' => $assetDescription['tradable'],
'class' => $class,
'text' => $text,
'classid' => $a['classid'],
'assetid' => $a['assetid'],
'instanceid' => $a['instanceid']
];
}else{
$inventory["priceNotFound"][] = $assetDescription["market_hash_name"];
}
}
}
About your mistake:
are you Sure your "prices.txt" contains market_hash_name?
I don't see any other issue yet, operationg on the data you have provided in comment, I got print of variable $assetDescription. Please doublecheck variable $prices.

Make separate php arrays from one json file

I have this json source file:
{
"results":
[
{
"movie_title":"A Monster Calls",
"cinema":"downtown"
},
{
"movie_title":"A Monster Calls",
"cinema":"uptown"
},
{
"movie_title":"A Monster Calls",
"cinema":"downtown"
},
{
"movie_title":"A Monster Calls",
"cinema":"downtown"
}
]
}
and I am writing my array like this (simplified for clarity):
$json_data = json_decode($html, true);
for($i = 0; $i < count($json_data['results']); $i++) {
$movieTitle = $json_data['results'][$i]["movie_title"];
$cinema = $json_data['results'][$i]["cinema"];
$moviesList[]= array(
"movieTitle" => $movieTitle,
"cinema" => $cinema
);
}
But what I want to do is output 2 separate arrays. One is all films showing in "downtown" cinema, and the other array all films showing in "uptown". The order in the json file will change, so I have to do it by name.
What's the best way to do this?
$downtownArray = array();
$uptownArray = array();
$json_data = json_decode($html, true);
for($i = 0; $i < count($json_data['results']); $i++) {
$movieTitle = $json_data['results'][$i]["movie_title"];
$cinema = $json_data['results'][$i]["cinema"];
if ($cinema == 'uptown') {
$uptownArray[]= array(
"movieTitle" => $movieTitle,
"cinema" => $cinema
);
} else {
$downtownArray[]= array(
"movieTitle" => $movieTitle,
"cinema" => $cinema
);
}
}
foreach ($json_data['results'] as $result) {
$cinema = $result['cinema'];
$moviesList[$cinema] []= [
"movieTitle" => $result['movie_title'],
// ...
];
}
The code classifies the results by the cinema field and stores them into $moviesList array. So, for example, the uptown results will be stored into $moviesList['uptown'].
You may try something like this
$json_data = json_decode($html, true);
$moviesDwn=array();
$moviesUp=array();
for($i = 0; $i < count($json_data['results']); $i++) {
$movieTitle = $json_data['results'][$i]["movie_title"];
$cinema = $json_data['results'][$i]["cinema"];
if ($json_data['results'][$i]["cinema"]='uptown')
$moviesUp[]= array(
"movieTitle" => $movieTitle,
"cinema" => $cinema
);
else if ($json_data['results'][$i]["cinema"]='updown')
$moviesDwn[]= array(
"movieTitle" => $movieTitle,
"cinema" => $cinema
);
}
First of all please , FIXyou JSON ,as it has some extra comma and then try with below codes
If you want to just separate the two array than use foreach(){};
foreach ($json_data['results'] as $result) {
$DownTown_List[$result['cinema']] []= $result['movie_title'];
}
OR
if you want to do other operation with the Indexes then use for(){};
for($i = 0; $i < count($json_data['results']); $i++) {
if($json_data['results'][$i]["cinema"] === "downtown"){
$DownTown_List["downtown"][] = $json_data['results'][$i]["movie_title"];
}
if($json_data['results'][$i]["cinema"] === "uptown"){
$DownTown_List["uptown"][] = $json_data['results'][$i]["movie_title"];
}
}
echo "<pre>";print_r($DownTown_List);exit;
OUTPUT
Array
(
[downtown] => Array
(
[0] => A Monster Calls
[1] => A Monster Calls
[2] => A Monster Calls
)
[uptown] => Array
(
[0] => A Monster Calls
)
)

How to merge multiple arrays in Codeigniter

I am trying to merge two arrays, but getting NULL. Below is my code
$a = 1;
foreach($codes as $values) {
$id = $values['id'];
$post_data = array (
"id" => $id,
"name" => $this->input->post('Name'),
"from_date" => $this->input->post('FromDate'),
"to_date" => $this->input->post('ToDate')
);
$this->data['output' . $a++] = $this->my_modal->simple_post($post_data);
}
$this->data['output'] = array_merge($this->data['output1'], $this->data['output2']);
var_dump($this->data['output']);
Any suggestions will be appreciated. Thanks..
You have to delete the first parameter (NULL) of array_merge();
And what is $this->input->$id? Don't you mean $id?
And in this environment, it's better to use array_push();:
$a = 1;
$this->data['output'] = array();
foreach($codes as $values)
{
$id = $values['id'];
$post_data = array (
"id" => $id,
"name" => $this->input->post('Name'),
"from_date" => $this->input->post('FromDate'),
"to_date" => $this->input->post('ToDate')
);
$new_data = $this->my_modal->simple_post($post_data);
array_push($this->data['output'], $new_data);
}
var_dump($this->data['output']);
$a = 1;
$this->data['output'] = array();
foreach($codes as $values){
$id = $values['id'];
$post_data = array (
"id" => $id,
"name" => $this->input->post('Name'),
"from_date" => $this->input->post('FromDate'),
"to_date" => $this->input->post('ToDate')
);
$data['output2']= $this->my_modal->simple_post($post_data);
if(count($this->data['output1']) > 1) {
$this->data['all'] = array_merge($this->data['output1'],$data['output2']);
}else {
$this->data['all'] = $data['output1'];
}
}
print_r($this->data['all']);
Your code is perfectly right, the only problem is that you start the counter with $a = 1, and do $a++ which will result in 2. So the output1 does not exist. However if you write (notice the subtle change):
$a = 1;
foreach($codes as $values) {
$id = $values['id'];
$post_data = array (
"id" => $id,
"name" => $this->input->post('Name'),
"from_date" => $this->input->post('FromDate'),
"to_date" => $this->input->post('ToDate')
);
$this->data['output' . $a] = $this->my_modal->simple_post($post_data); // $a = 1 now
$a++; // $a becomes 2 here
}
$this->data['output'] = array_merge($this->data['output1'], $this->data['output2']);
var_dump($this->data['output']);

Symfony2 undefined offset: 0 error with lottery project

In my lottery project I have 5 tickets, in which you select numbers and buy. The thing is, you can only buy the tickets if you buy them in order... For example:
Ticket 1 Ticket 2 Ticket 3 Ticket 4 Ticket 5
If you add numbers to the ticket 1 and then the others it works... If you skip the ticket 1 and add numbers to the other ones, when you try to buy you get this error:
ContextErrorException: Notice: Undefined offset: 0 in C:\wamp\www\Digidis\front\src\MediaparkLt\UserBundle\Service\MoneyManager.php line 313

As you can see first it gets the ticket 1, which is empty(or 0) and thats why it causes the error... How can I make it so that it skips the empty tickets?

From what I see the bet type in your object is set to "type":"simple" and numbers1":"0,0,0,0,0"
$is_ticket_filled = ((int) str_replace(',', '', $t['numbers'])) > 0;
//(int) 00000 = 0
if (!$is_ticket_filled) {
unset($tickets[$k]);
}
Is causing the issue since unset does not reset the array indexes.
http://ideone.com/5q74Wv
Then later you iterate using for($k=0; $k < count($tickets); $k++)
You should instead rebase the array after using unset($tickets[$k])
if ($bets->type === 'simple') {
//...
$tickets = array_values($tickets);
}
or check the existence of the ticket when iterating over indexes
$ticketCount = count($tickets);
for ($k=0; $k < $ticketCount; $k++) {
if (false === isset($tickets[$k]) {
continue;
}
//...
}
or easier still, iterate over the existing tickets array using foreach instead of for.
foreach ($tickets as $k => $ticket) {
//...
}
Then change $tickets[$k] with just $ticket since $k is not used anywhere else.
