Interact with Firebase from PHP.

firebase.php

<?php

// Constants
$FIREBASE = "_YOUR_FIREBASE_URL_";
$NODE_DELETE = "temperature.json";
$NODE_GET = "temperature.json";
$NODE_PATCH = ".json";
$NODE_PUT = "temperature.json";

// Data for PUT
// Node replaced
$data = 32;

// Data for PATCH
// Matching nodes updated
$data = array(
    "temperature" => 42
);

// JSON encoded
$json = json_encode( $data );

// Initialize cURL
$curl = curl_init();

// Create
// curl_setopt( $curl, CURLOPT_URL, $FIREBASE . $NODE_PUT );
// curl_setopt( $curl, CURLOPT_CUSTOMREQUEST, "PUT" );
// curl_setopt( $curl, CURLOPT_POSTFIELDS, 32 );

// Read
// curl_setopt( $curl, CURLOPT_URL, $FIREBASE . $NODE_GET );

// Update
curl_setopt( $curl, CURLOPT_URL, $FIREBASE . $NODE_PATCH );
curl_setopt( $curl, CURLOPT_CUSTOMREQUEST, "PATCH" );
curl_setopt( $curl, CURLOPT_POSTFIELDS, $json );

// Delete
// curl_setopt( $curl, CURLOPT_URL, $FIREBASE . $NODE_DELETE );
// curl_setopt( $curl, CURLOPT_CUSTOMREQUEST, "DELETE" );

// Get return value
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );

// Make request
// Close connection
$response = curl_exec( $curl );
curl_close( $curl );

// Show result
echo $response . "\n";

UPDATE

What about the Firebase data that needs authentication for access. How would you handle that?

great

Thank you all for the comments and feedback. Note that I have not worked with Firebase for more than a year, and as such the API may have changed, and this code may be out of date (probably is out of date). I honestly never expected that people would find this gist and use it - I just posted it for my own memory. I am not actively maintaining this code.

I am facing problem in below mentioned code ,I am beginner please help!
How to setup??
// Constants
$FIREBASE = "YOUR_FIREBASE_URL";
$NODE_DELETE = "temperature.json";
$NODE_GET = "temperature.json";
$NODE_PATCH = ".json";
$NODE_PUT = "temperature.json";
