Google Custom Search is a service that allows website owners to add a customized search engine to their website. With Google Custom Search, users can search for content within a specific website or group of websites.

Website owners can create a Custom Search Engine by defining a list of websites to search, creating a search box and search results page that match their website’s look and feel, and then integrating the search box into their website. The search results are generated by Google’s search technology, but are filtered to only include results from the specified websites.

Google Custom Search also provides an API that allows developers to access search results programmatically and integrate them into their own applications. This API is subject to usage limits and requires an API key to use.

Overall, Google Custom Search is a useful tool for website owners who want to provide a customized search experience for their users, and for developers who want to integrate search results into their own applications.

Follow this video for complete guidance :

Step 1

First, you need to enable the Google Custom Search API and obtain an API key. Go to the Google Developers Console (https://console.developers.google.com/), create a new project, and enable the Custom Search API. Then, create a new API key.

Step 2

In your PHP code, use the following code to make a request to the Google Custom Search API:

// Set your API key and search engine ID
$api_key = 'your_api_key';
$search_engine_id = 'your_search_engine_id';

// Set the search query
$search_query = 'your_search_query';

// Set the API endpoint URL
$api_endpoint_url = "https://www.googleapis.com/customsearch/v1?key={$api_key}&cx={$search_engine_id}&q={$search_query}";

// Make a request to the API and get the response
$response_json = file_get_contents($api_endpoint_url);
$response = json_decode($response_json, true);

Step 3

You can now use the $response variable to access the search results. The $response variable is an associative array that contains the search results in the items key. Here’s an example of how to display the search results:

foreach ($response['items'] as $result) {
    echo '<h3><a href="' . $result['link'] . '">' . $result['title'] . '</a></h3>';
    echo '<p>' . $result['snippet'] . '</p>';
}

This code will display the title and snippet of each search result as a heading and paragraph, respectively.
