Accessing Certain JSON Elements - php

Question

How would I go about accessing these elements from a Shopify JSON in PHP
JSON:
{
"orders":[
{ "note_attributes":[
{
"name":"field1",
"value":"xxxxxxxxxxxx"
},
{
"name":"field2",
"value":"xxxxxx"
},
{
"name":"field3",
"value":"xxxxxx"
}
],
This is just snippet of the object. How would I access each value and assign it to the name? Eg this $req['account_id'] would equal the value for that name tag. This is how am trying to do it but it's not working:
foreach ($order['note_attributes'] as $attributes) {
$req = array();
$req[$attributes->name] = $attributes[$attributes->value];
}
I would then like to echo $req['account_id'] and that would = xxxxxxxxx#gmail.com but it's not working any suggestions or fixes?

When iterating over Objects properties, one approach is to use (as you have) foreach
// accessing property
foreach ($objects as $object) {
echo $object->property;
}
// accessing key-value pair
foreach ($object as $key => $value) {
echo "$key => $value\n";
}
An example:
$attributes = array();
.
.
foreach($note_attributes as $note_attribute) {
$key = $note_attribute['name'];
$value = $note_attribute['value'];
$attributes[$key] = $value;
}
The structure should be in key-value pairs. ie.
attributes [
"account1234" => "abc#xxx.com",
"account_password" => "asdasdasd"
]
Hope this helps.
Update: as Roopendra mentioned, json_decode() with a TRUE flag with return an associative array, else stdClass.
