PHP array problems - grouping array - php

Question

I'm trying to convert some array values (group then actually), but I don't know how to do that.
I have something like this:
[
{
"nsr": "000086310",
"type": "3",
"date": "2015-07-18",
"time": "00:06",
"pis": "12138790985"
},
{
"nsr": "000086313",
"type": "3",
"date": "2015-07-18",
"time": "00:33",
"pis": "16073736879"
},
{
"nsr": "000086316",
"type": "3",
"date": "2015-07-18",
"time": "00:58",
"pis": "16634402451"
},
{
"nsr": "000086316",
"type": "3",
"date": "2015-07-19",
"time": "00:58",
"pis": "98127981729"
},
{
"nsr": "000086316",
"type": "3",
"date": "2015-07-19",
"time": "00:58",
"pis": "12398712938"
}
]
And I want to convert to this:
[
"date" : "2015-07-18",
"pis" : [
"12138790985",
"16073736879",
"16634402451"
]
],
[
"date" : "2015-07-19",
"pis" : [
"98127981729",
"12398712938"
]
]
I tried to do something like this:
public function index()
{
$this->setTxtData('../../txt_files/CAP 3 18 07 2015 FABRICA.txt');
$txtdata = $this->getTxtData();
$dataToCompare = array();
foreach($txtdata as $ponto){
$time = $ponto['time'];
$date = $ponto['date'];
$pis = $ponto['pis'];
// $dataToCompare = array();
// if(strpos($ponto['pis'], '00000000000') === false){
// $pis_temp[][''] = $ponto['pis'];
// }
if(isset($dataToCompare)){
foreach($dataToCompare as $dateToSet){
if($dateToSet['data'] == $date){
$dateToSet['pis'][] = $pis;
}
else{
$dateToSet['data'] = $date;
$dateToSet['pis'][] = $pis;
}
}
}
else{
$dataToCompare = array(
[
'data' => $date,
'pis' => array($pis)
]
);
}
$funcionario_id = DB::table('funcionario')
->select('id')
->where('pis_pasep', '=', $pis)
->pluck('id');
if($funcionario_id !== null){
$validate = DB::table('horas_trabalho')
->select('id')
->where('hora', '=', $time)
->where('data', '=', $date)
->where('funcionario_id', '=', $funcionario_id)
->pluck('id');
if($validate === null){
DB::table('horas_trabalho')
->insert([
'hora' => $time,
'data' => $date,
'funcionario_id' => $funcionario_id
]);
}
}
}
//-------------------------------------Lógica para faltas-----------------------------------
/**
* Pega o pis
*/
$db_all_funcionarios = DB::table('funcionario')
->select('pis_pasep')
->where('pis_pasep', '!=', 0)
->get();
foreach($db_all_funcionarios as $pis){
if(strpos($pis->pis_pasep, '00000000000') !== true){
$global_pis[] = $pis->pis_pasep;
}
}
// $faltantes = array_diff($pis_temp, $global_pis);
// foreach($faltantes as $faltante){
// DB::table('falta')
// ->insert([
// 'data' => date('2015-07-16')
// ]);
// }
// $ponto_db[] = DB::table('horas_trabalho')
// ->join('funcionario', 'horas_trabalho.funcionario_id', '=', 'funcionario.id')
// ->select('funcionario.nome', 'horas_trabalho.hora', 'horas_trabalho.data')
// ->get();
return $txtdata;
}

Answer 1

I see the date in your filename and think you want group all entities at all:
$dataToCompare = array(
'date' => $txtData[0]['date'],
'pis' => array_map(function($el){return $el['pis'];}, $txtData)
);
For multiple dates:
$hash = array();
foreach ($txtData as $entity) {
if (!isset($hash[$entity['date']])) $hash[$entity['date']] = array();
$hash[$entity['date']][] = $entity['pis'];
}
$result = array();
foreach($hash as $date=>$pis) {
$result[] = array('date'=>$date, 'pis'=>$pis);
}

Answer 2

It might be a little sloppy, but it does the job. Or either way, it works as you wanted in the example:
<?php
$array = array(
0 => array(
"nsr" => "000086310",
"type" => "3",
"date" => "2015-07-18",
"time" => "00:06",
"pis" => "12138790985"
),
1 => array(
"nsr" => "000086313",
"type" => "3",
"date" => "2015-07-18",
"time" => "00:33",
"pis" => "16073736879"
),
2 => array(
"nsr" => "000086316",
"type" => "3",
"date" => "2015-07-18",
"time" => "00:58",
"pis" => "16634402451"
)
);
$newarray = array();
$pis = array();
foreach($array as $part){
array_push($pis,$part['pis']);
$newarray = array(
"date" => $part['date'],
"pis" => $pis
);
}
var_dump($newarray);
?>

$array = json_decode($str, true);
// make array date => pis
$tmp = array();
foreach ($array as $item) {
if (!isset($tmp[$item['date']])) $tmp[$item['date']]['pis'] = array();
$tmp[$item['date']]['pis'][] = $item['pis'];
}
// Than move date from key to item
$result = array();
foreach($tmp as $k=>$v)
$result[] = array('date' => $k, 'pis' => $v['pis']);
print_r($result);
