#Php json decode url code
If you want to access all the array data then it can be tiresome and time-consuming to write the code for accessing each at a time especially when the object is large. We access the China array object as below: " Įcho "Code: ".$data."" But when accessing the array items, we start counting from 0, hence the index of China in the array is 2. We can use PHP’s jsondecode() function for the same, which takes in a JSON encoded string and returns the corresponding PHP variable. For example, china is in the third position. In the very likely case of your JavaScript front-end sending JSON-based data back to your PHP server, you would need a way to decode the JSON data in a way that can be processed by PHP. To access the values of a country in the example above, you just have to know its object position in the array. You may have a large JSON object made of an array of objects, like in the example below: Looping through an object of objects with foreach()

Accessing data in a nested JSON objectĪ JSON object may comprise of json objects and arrays as the values in its name-value pairs such as in the example below: You access the data as in any other PHP associative array as in the example below: firstName. To access the PHP object data, you use the object operator ( ->) after the object name, followed by the key of the key-value pair. We use the built-in function json_decode() to convert the JSON string to the appropriate data type such as an object or an array.
