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.Male Female Name Gender $ ( '#gender' ). 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. For example, china is in the third position. 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() The easiest way of accessing all the data is decoding the object as an associative array.Įcho 'First Name: '.$data.''

This is the same as the name in the name-value pair in JSON object eg $data->firstName.

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.

$mydata = file_get_contents('php://input') Ī JSON file contains a JSON object and has a file extension of. To receive the above request data in the register.php file, just add file_get_contents('php://input') and assign it to a variable for processing eg:
