Web検索APIがあちこち提供終了しているのでbingのAPIを試す 簡易メモ

PHP 
<?php

$key = "APIキー";
$word = "検索文字列";

$url = 
    "https://api.datamarket.azure.com/Bing/Search/Web" . 
    "?Query=" . urlencode("'" . $word . "'") . 
    '&$format=json';

$options = array(
    "http" => array(
        "request_fulluri" => true,
        "header" => "Authorization: Basic " . base64_encode($key . ":" . $key)
    )
);

$context = stream_context_create($options);
$response = @file_get_contents($url, false, $context);
$ret = json_decode($response, true);
print_r($ret["d"]["results"]);

?>
