Make separate php arrays from one json file - php

Question

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?

Answer 1

$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
);
}
}

Answer 2

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
)
)
