How to Correctly Decode JSON POST Data in PHP?

Decoding JSON POST Data with PHP

When receiving a JSON POST request in PHP, it's crucial to understand the specific format of the incoming data. In this case, the issue arises from a spelling discrepancy between your code and the JSON string you're receiving.

To effectively decode JSON POST data:

1. Retrieve the Raw JSON String:
   Use file_get_contents('php://input') to read the incoming JSON data.
2. Decode and Parse the JSON String:
   Decode the raw JSON string using json_decode(file_get_contents('php://input'), true). This will convert the JSON into a PHP array.
3. Access the Array Values:
   Use the array key to access the properties within the decoded JSON. For example, to access the "operation" property:

$operation = $data["operacion"];

In your case, the JSON string has a property named "operacion" instead of "operation". Ensure that the spelling matches in both your code and the incoming JSON data. Additionally, using print_r($data) can provide insight into the structure of the received data.
