What are some alternative methods or libraries that can be used to create a PHP search engine for a MySQL database?

When creating a PHP search engine for a MySQL database, one alternative method is to use the Elasticsearch library. Elasticsearch is a powerful search engine that can be integrated with PHP to provide fast and efficient search capabilities for your database. Another option is to use the Sphinx search engine, which is specifically designed for full-text search in databases. Both Elasticsearch and Sphinx offer advanced search features and can be easily integrated with PHP to create a robust search engine for your MySQL database.

// Example using Elasticsearch library
require 'vendor/autoload.php';

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();

$params = [
    'index' => 'my_index',
    'body' => [
        'query' => [
            'match' => [
                'my_field' => 'search_keyword'
            ]
        ]
    ]
];

$response = $client->search($params);

print_r($response);
