PHP convert JSON array to nested - php

Question

I'm trying to get JSON by name and save it as a variable with everything related to that nest,
what would the best way to accomplish this?
(in my scenario the names are unique)
[{
"name": "Joe",
"age": "30",
"gender": "male"
},
{
"name": "Logan",
"age": "27",
"gender": "male"
}]
to something like this
{
"Joe": [{
"name": "Joe",
"age": "30",
"gender": "male"
}],
"Logan": [{
"name": "Logan",
"age": "27",
"gender": "male"
}]
}
i need to be able to search on the name to get the correct one, the API switches order so can't get it from just id

Hi This might helps you
$list = '[
{
"name":"Joe",
"age":"30",
"gender":"male"
},
{
"name":"Logan",
"age":"27",
"gender":"male"
}]';
$newjson = json_decode($list, true);
$final = [];
foreach ($newjson as $key => $value) {
$final[$value['name']][]=$value;
}
$finaloutput = json_encode($final, true);
echo "<pre>";
print_r($finaloutput);
echo "</pre>";
exit;
The output is
{"Joe":
[{"name":"Joe","age":"30","gender":"male"}],
"Logan":
[{"name":"Logan","age":"27","gender":"male"}]}

The Laravel Collections Library is a very useful lib to use cases like yours.
For this problem you could use the keyBy method!
$json = '[
{
"name":"Joe",
"age":"30",
"gender":"male"
},
{
"name":"Logan",
"age":"27",
"gender":"male"
}
]';
$array = collect(json_decode($json, true))->keyBy('name')->all();
print_r($array); // will be the array with the keys defined by the name!
See https://laravel.com/docs/5.5/collections#method-keyby
