How Can I Receive and Process JSON POST Data in PHP?

Receive JSON POST with PHP

In a payment interface website, retrieving data from a JSON POST can be challenging. To decode the JSON, follow these steps:

1. Enable Raw PHP:

Ensure that PHP is receiving raw data by adding the following line to the beginning of your script:

<?php
header('Content-Type: application/json');

2. Retrieve JSON from PHP Input:

Use the following code to retrieve the JSON string:

$data = json_decode(file_get_contents('php://input'), true);

3. Access JSON Data:

Now that you have the decoded JSON data, you can access its properties by using the object notation, such as:

$data["operacion"]
$data["operacion"]["tok"]

4. Handle Potential Issues:

• Ensure that the JSON format matches the documentation from the payment site.
• Check the spelling of property names, which should match the JSON exactly.
• Try echoing the JSON string from PHP input to verify that it's being received correctly:

echo file_get_contents('php://input');
