Firebase |如何在php中显示信息

Question

你好 我在firebase中设置了一个简单的json数据库，我试图在php页面上显示它。

它是这样的？

<?php
// Constants
$FIREBASE = "https://pu***44.firebaseio.com";
$NODE_DELETE = "employee.json";
$NODE_GET = "employee.json";
$NODE_PATCH = ".json";
$NODE_PUT = "employee.json";
// Data for PUT
// Node replaced
$data = 32;
// Data for PATCH
// Matching nodes updated
$data = array(
    "employee" => 42
);
// JSON encoded
$json = json_encode( $data );
// Initialize cURL
$curl = curl_init();

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

curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
// Make request
// Close connection
$response = curl_exec( $curl );
curl_close( $curl );
// Show result
echo $response . "\n";
?>

只是让自己清楚，我希望它能从json文件中显示一个项目。让我们说第一个。 谢谢！
