用PHP解析嵌套的JSON

Question

{
    "listing": {
        "@attributes": {
            "domain": "example.com"
        },
        "tld": "com",
        "sld": "example",
        "owner": "John Smith"
    }
}

I am needing to iterate through this JSON array and put the values into PHP variables so that I can return the values.

Example:

echo $sld;

would print:

example

Would I need to do this with a foreach loop (and if so how would I format this) or is there a easy built in function such as extract() that will do this?

Answer 1

<?php 
$json = '{
    "listing": {
        "@attributes": {
            "domain": "example.com"
        },
        "tld": "com",
        "sld": "example",
        "owner": "John Smith"
    }
}';

$decoded_array = json_decode($json, true);
echo $decoded_array['listing']['sld'];//example
?> 

Answer 2

You can use

json_decode('your json string', true);

Which will return an associative array of your string which you can then loop though.
