Search in array in json file - php

Question

I have an array which has a key with multiple content. I want to get that array which includes the key that I search .
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$results = array_filter($arr['people'], function($people) {
return $people['id'] == 8080;
});
echo json_encode($results);
This will return:
{"id":"8080","content":"foo","member":[123,456],"interval":7}
I want that:
$results = array_filter($arr['people'], function($people) {
return $people['member'] == 123;
});
And this does not work.
Have somebody an idea?

Answer 1

As #JonStirling said in comment. Use in_array() function.
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$searchId = 123;
$results = array_filter($arr['people'], function($people) use ($searchId) {
return in_array($searchId, $people['member']);
});
echo json_encode($results);
Result:
[{"id":"8080","content":"foo","member":[123,456],"interval":7}]

See if this helps:
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$results = array_filter($arr['people'], function($people) {
for($i=0; $i<count($people['member']); $i++){
return $people['member'][$i] == 123;
}
});
echo json_encode($results);
The out come will be:
[{"id":"8080","content":"foo","member":[123,456],"interval":7}]

If you want to do it withouth 'array_filter' you can try this:
function search($arr, $id, $arrayValue)
{
$people = null;
foreach ($arr['people'] as $a)
{
if ($a['id'] == $id)
{
$people = $a;
}
}
$arrayWeAreLookingFor = null;
foreach ($people as $property => $value)
{
if (is_array($value))
{
foreach ($value as $v)
{
if ($v == $arrayValue)
{
$arrayWeAreLookingFor = $people[$property];
}
}
}
}
return $arrayWeAreLookingFor;
}
var_dump(search($arr, 8080, 123));
