How can data be transferred from PHP to a Python machine?

Data can be transferred from PHP to a Python machine by using a common data interchange format such as JSON. PHP can encode the data into JSON format and send it to the Python machine via a HTTP request. On the Python side, the data can be decoded from JSON format and processed accordingly.

<?php
// Data to be transferred
$data = array('key1' => 'value1', 'key2' => 'value2');

// Encode data into JSON format
$json_data = json_encode($data);

// Send data to Python machine via HTTP request
$python_url = 'http://python-machine-url';
$ch = curl_init($python_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_exec($ch);
curl_close($ch);
?>
