how to search inside two JSON files at a time in PHP - php

Question

I have two JSON files of same format, forexample
1st JSON File
{
"data": {
"business": {
"id": "3NzA0ZDli",
"customers": {
"pageInfo": {
"currentPage": 1,
"totalPages": 695,
"totalCount": 1389
},
"edges": [
{
"node": {
"id": "QnVzaW5lc3M6Z",
"name": "Joe Biden",
"email": "joe#mail.com"
}
},
{
"node": {
"id": "QnVzaW5lc3M6Z",
"name": "MULTIMEDIA PLUMBUM",
"email": "mdi#mail.com"
}
}
]
}
}
}
}
2nd JSON file
{
"data": {
"business": {
"id": "3NzA0ZDli",
"customers": {
"pageInfo": {
"currentPage": 2,
"totalPages": 695,
"totalCount": 1389
},
"edges": [
{
"node": {
"id": "QnVzaW7dQ8N",
"name": "Mark",
"email": "mark#mail.com"
}
},
{
"node": {
"id": "QnVzaW5l5Gy9",
"name": "Trump",
"email": "trump#mail.com"
}
}
]
}
}
}
}
Each user has a unique "id", I want to get their id by searching their name in php, how can I do this
This is my PHP script
$json1 = file_get_contents("1.json");
$json2 = file_get_contents("2.json");
$result1 = json_decode($json1, true);
$result2 = json_decode($json2, true);
foreach ($result2 as $k => $v) {
if ($v['data']['business']['edges']['customers']['node']['name'] == "Trump") break;
}
echo $result[$k]['data']['business']['edges']['customers']['node']['name']; //I want to get id for trump "QnVzaW5l5Gy9"
Each user has a unique "id", I want to get their id by searching their name in php. How can I get id by searching name in both files at a time?
Thanks

Answer 1

Since you are looping through json file it will search inside of "data" so you can't use $v['data']
Also since edges is also array that have same values and you want to search inside of it you must make loop on that also
Here is example
foreach ($result2 as $k => $v) {
foreach ($v['business']['customers']['edges'] as $val) {
if ($val['node']['name'] == 'Trump') {
echo '<pre>';
// and now you can access any of those values, echo $val['node']['id'];
print_r($val['node']);
echo '</pre>';
}
}
}
Output
Array
(
[id] => QnVzaW5l5Gy9
[name] => Trump
[email] => trump#mail.com
)
EDIT
Since you want to search in both files at a same time you can put them into array and then use it like this
$json1 = file_get_contents("1.json");
$json2 = file_get_contents("2.json");
$result1 = json_decode($json1, true);
$result2 = json_decode($json2, true);
$joined_result = array($result1, $result2);
foreach($joined_result as $val) {
// this will take all nodes where you will search
$node = $val['data']['business']['customers']['edges'];
foreach ($node as $value) {
if ($value['node']['name'] == 'Trump') {
echo '<pre>';
print_r($value['node']);
echo '</pre>';
}
}
}

You have two questions there, no?
The first question I get is "How to get the ID for a certain name"
$node = $result2['data']['business']['customers']['edges']['node'];
if ($node['name'] == "Trump") echo $node['id'];
Almost your code, but I echo the ID when the name matches "Trump".
The second question I see is "How do search both json data at once"
$json1 = file_get_contents("1.json");
$json2 = file_get_contents("2.json");
$result1 = json_decode($json1, true);
$result2 = json_decode($json2, true);
$all_data = [$result1, $result2];
foreach($all_data as $data) {
$node = $data['data']['business']['customers']['edges']['node'];
if ($node['name'] == "Trump") echo $node['id'];
}
Transforming both json data to be in an array and then simply looping over the whole array should do the trick.
