Question

I need your help..I would like to call a json value using a json value...
here's my sample json...
first json:
{
"first_name": "Richard Catibog",
"last_name": "",
"display_name": "Richard Catibog ",
"roles": {
"owner": false,
"administrator": true
},
"login_count": 108,
"enabled": true,
"departments": [
1817719575,
1817719887,
1817722991
],
"id": 4142095,
"last_login": "2017-07-12T10:03:57Z",
"create_date": "2017-04-28T12:09:57Z",
"email": "richard.catibog+21757948948#51talk.com"

{
"first_name": "Rovi Cruz",

"display_name": "Rovi Roy Cruz ",
"roles": {
"owner": false,
"administrator": true

I would like to call the id on the second and echo the names using the departments id list on first json...
here's what i get...
but the result that i want to see is AA Fees Support [L2], Lesson and Fee Support and Technical Support...
thank you, hope you can help me...

Answer 1

In this I made an array $desc that is keyed on the departments id numbers so you can easily convert the id to a Descrition
$js1 = '{
"first_name": "Richard Catibog", "last_name": "",
"display_name": "Richard Catibog ",
"roles": { "owner": false,"administrator": true},
"login_count": 108,"enabled": true,
"departments": [1817719575,1817719887,1817722991],
"id": 4142095,"last_login": "2017-07-12T10:03:57Z",
"create_date": "2017-04-28T12:09:57Z",
"email": "richard.catibog+21757948948#51talk.com"
}';
$js2 = '[
{
"description": "Fees Support for American Academy",
"settings": {},"enabled": false,"id": 1817719575,
"name": "AA Fees Support [L2]"
},
{
"description": "American Academy",
"settings": {},"enabled": true,"id": 1817722991,
"name": "Lesson and Fee Support"
},
{
"description": "Technical Support",
"settings": {},"enabled": true,"id": 1817719887,
"name": "Technical Support"
}
]';
$first = json_decode($js1);
//print_r($first);
$second = json_decode($js2);
//print_r($second);
// make array key'd on the id
$desc = [];
foreach ($second as $s) {
$desc[$s->id] = $s;
}
print_r($desc);
// go through all the dept id's in the first array
// getting a matching desctipyion from array 2
foreach ( $first->departments as $dept) {
echo $desc[$dept]->description . PHP_EOL;
}
UPDATE: After the first json data structure got changed to an array of objects
NOTE I changed your first json data structure to make it valid JSON by adding [] around the 2 objects to make a valid JSON data structure i.e. an array of objects.
All you need to do in this case is add a loop to lop over the now array of objects.
$js1 = '[{
"first_name": "Richard Catibog",
"last_name": "",
"display_name": "Richard Catibog ",
"roles": { "owner": false, "administrator": true },
"login_count": 108,
"enabled": true,
"departments": [ 1817719575, 1817719887, 1817722991 ],
"id": 4142095,
"last_login": "2017-07-12T10:03:57Z",
"create_date": "2017-04-28T12:09:57Z",
"email": "richard.catibog+21757948948#51talk.com"
},
{
"first_name": "Rovi Cruz",
"last_name": "",
"display_name": "Rovi Roy Cruz ",
"roles": { "owner": false, "administrator": true },
"login_count": 98,
"enabled": true,
"departments": [ 1817719575, 1817719887, 1817722991 ],
"id": 4225009,
"last_login": "2017-07-13T00:37:27Z",
"create_date": "2017-06-05T06:15:49Z",
"email": "rovi.cruz+21821290968#51talk.com"
}]';
$js2 = '[
{
"description": "Fees Support for American Academy",
"settings": {},"enabled": false,"id": 1817719575,
"name": "AA Fees Support [L2]"
},
{
"description": "American Academy",
"settings": {},"enabled": true,"id": 1817722991,
"name": "Lesson and Fee Support"
},
{
"description": "Technical Support",
"settings": {},"enabled": true,"id": 1817719887,
"name": "Technical Support"
}
]';
$first = json_decode($js1);
//print_r($first);
$second = json_decode($js2);
//print_r($second);
// make array key'd on the id
$desc = [];
foreach ($second as $s) {
$desc[$s->id] = $s;
}
//print_r($desc);
//Loop through all the first array of object
foreach ( $first as $f) {
// go through all the dept id's in the first array
// getting a matching desctipyion from array 2
foreach ( $f->departments as $dept) {
echo $desc[$dept]->description . PHP_EOL;
}
echo PHP_EOL;
}
RESULT
Fees Support for American Academy
Technical Support
American Academy
Fees Support for American Academy
Technical Support
American Academy

Answer 2

here you go
$json1 = '{
"first_name": "Richard Catibog",
"last_name": "",
"display_name": "Richard Catibog ",
"roles": {
"owner": false,
"administrator": true
},

"enabled": true,
"departments": [
1817719575,
1817719887,
1817722991
],
"id": 4142095,
"last_login": "2017-07-12T10:03:57Z",
"create_date": "2017-04-28T12:09:57Z",
"email": "richard.catibog+21757948948#51talk.com"
}
';
$json2 ='[
{
"description": "Fees Support for American Academy",
"settings": {
},
"enabled": false,
"id": 1817719575,

},
{
"description": "American Academy",

},
{
"description": "Technical Support",
"settings": {
},
"enabled": true,
"id": 1817719887,
"name": "Technical Support"
}
]';
$json1 = json_decode($json1, true);
$json2 = json_decode($json2, true);
$department = function($id) use($json2) {
foreach($json2 as $dep) {
if($dep["id"] == $id) {
return $dep;
}
}
return false;
};
foreach($json1["departments"] as $id) {
$dep = $department($id);
if(is_array($dep)) {
echo sprintf("id: %s, name: %s\n", $id, $dep["name"]);
}
}
