PHP How to get a particular JSON values/parameter - php

Question

This is my JSON Response came from an URL API. I use GuzzleHttp\Client and json_decode() inorder to manage.
[{
"INDEX_ID": "0",
"NOTES": "0; Farming"
},
{
"INDEX_ID": "1",
"NOTES": "Fruit Name; List of Fruits;"
},
{
"INDEX_ID": "2",
"NOTES": "Apple"
},
{
"INDEX_ID": "3",
"NOTES": "Orange"
},
{
"INDEX_ID": "4",
"NOTES": "Grapes"
},
{
"INDEX_ID": "5",
"NOTES": "Mango"
},
{
"INDEX_ID": "6",
"NOTES": "Animal Name; List of Animal;"
},
{
"INDEX_ID": "7",
"NOTES": "Pig"
},
{
"INDEX_ID": "8",
"NOTES": "Goat"
},
{
"INDEX_ID": "9",
"NOTES": "Cow"
}]
But I only need to save list of Fruits in my logfile. Can someone help me how to exclude the other json parameters and get only the particular json parameters using foreach loop or any method inorder to get that result.
I just want it to be like this:
[
{
"NOTE_NO." : "001",
"CATEGORY" : "FRUITS",
"LISTS_TO_BUY" : [
{
"FRUITS": "Apple"
},
{
"FRUITS": "Orange"
},
{
"FRUITS": "Grapes"
},
{
"FRUITS": "Mango"
}
]
}
]
He're my codes so far:
$response_body = json_decode($json_response, true);
$json_new_param = [];
foreach ($response_body as $value) {
$json_new_param[] = [
'FRUITS' => $value['NOTES']
];
}
$header = [
[
'NOTE_NO.' => '001',
'CATEGORY' => 'FRUITS',
'LISTS_TO_BUY' => $json_new_param
]
];
echo json_encode($header);
$json_response is the response given above.

Answer 1

You might use array_reduce to return an array where the key will be the first word from the value using implode which has this structure: "NOTES": "Fruit Name; List of Fruits;". The key for this would then be "Fruits".
During the array_reduce keep track of the current key using a variable $currKey
At the end you could then get the data by using "FRUIT" (Which is the first word) as the array key: $response_body["FRUIT"]
$response_body = json_decode($json_response, true);
$currKey = "0";
$response_body = array_reduce($response_body, function ($carry, $item) use (&$currKey){
if (strpos($item['NOTES'], 'Name; List') !== false) {
$currKey = strtoupper(explode(" ", $item["NOTES"], 2)[0]);
return $carry;
}
$carry[$currKey][] = ["FRUITS" => $item["NOTES"]];
return $carry;
});
$result = [
[
"NOTE_NO" => "001",
"CATEGORY" => ($name = "FRUITS"),
"LISTS_TO_BUY" => $response_body["FRUIT"]
]
];
echo json_encode($result, JSON_PRETTY_PRINT);
That will result in:
[
{
"NOTE_NO": "001",
"CATEGORY": "FRUITS",
"LISTS_TO_BUY": [
{
"FRUITS": "Apple"
},
{
"FRUITS": "Orange"
},
{
"FRUITS": "Grapes"
},
{
"FRUITS": "Mango"
}
]
}
]

Try this code .
$json_new_param = [];
$fruitFlag = false;
foreach ($response_body as $value) {
if(strpos($value['NOTES'],'Fruit Name') !== false){
$fruitFlag = true;
continue;
}
if(strpos($value['NOTES'],'Animal Name') !== false){
$fruitFlag = false;
}
if($fruitFlag == true){
$json_new_param[] = [
'FRUITS' => $value['NOTES']
];
}
}
echo json_encode($json_new_param, JSON_PRETTY_PRINT);
