Quickstart: Search for images using Bing Image Search REST API and PHP

Artikkeli
10/28/2020

Use this quickstart to make your first call to Bing Image Search API and receive a JSON response. The simple application in this article sends a search query and displays the raw results.

Although this application is written in PHP, the API is a RESTful Web service compatible with any programming language that can make HTTP requests and parse JSON.

The source code for this sample is available on GitHub.

Prerequisites

PHP 5.6.x or later

Create and initialize the application

To run this application, follow these steps:

Make sure secure HTTP support is enabled in your php.ini file. For Windows, this file is located in C:\windows.
Create a new PHP project in your favorite IDE or editor.

Define the API endpoint, your subscription key, and search term.

$endpoint = 'https://api.bing.microsoft.com/v7.0/images/search';
// Replace the accessKey string value with your valid access key.
$accessKey = 'enter key here';
$term = 'tropical ocean';

Construct and perform an HTTP request

Use the variables from the last step to prepare an HTTP request to the Image Search API.

$headers = "Ocp-Apim-Subscription-Key: $key\r\n";
$options = array ( 'http' => array (
                        'header' => $headers,
                        'method' => 'GET' ));

Send the web request and get the JSON response.

$context = stream_context_create($options);
$result = file_get_contents($url . "?q=" . urlencode($query), false, $context);

Process and print the JSON

Process and print the returned JSON response.

$headers = array();
    foreach ($http_response_header as $k => $v) {
        $h = explode(":", $v, 2);
        if (isset($h[1]))
            if (preg_match("/^BingAPIs-/", $h[0]) || preg_match("/^X-MSEdge-/", $h[0]))
                $headers[trim($h[0])] = trim($h[1]);
    }
    return array($headers, $result);
