PHP implements open source Kibana search and analysis engine

With the rapid growth of data volume, people's demand for data search and analysis is also becoming stronger and stronger. Kibana, as a powerful and easy-to-use open source search and analysis engine, has been widely used. This article will introduce how to use PHP to implement the Kibana search and analysis engine.

Kibana Introduction

Kibana is an open source data analysis and visualization platform that works with Elasticsearch to easily search, analyze and visualize big data. As a tool for developers and enterprise users, Kibana can help users quickly discover patterns, trends and anomalies in data, and quickly generate various reports and visual charts.

The main features of Kibana include:

• Visual report generation: Kibana can generate various charts and reports to allow users to understand the data more intuitively.
• Efficient data search: Kibana has a powerful built-in search engine that can quickly search for the required data.
• Flexible data filtering: Kibana supports using various filtering conditions to filter the required data.
• Comprehensive data statistics: Kibana provides a variety of statistical methods that can analyze the quantity, proportion, trend, etc. of data.
• Easy-to-use user interface: Kibana’s user interface is simple and intuitive, and users can get started quickly.

Use PHP to implement Kibana search and analysis engine

PHP is a programming language widely used in Web development, with rich extension libraries and excellent development tools. By using the PHP extension library, we can easily implement Kibana's search and analysis functions. This section will introduce how to use PHP to implement the Kibana search and analysis engine.

First you need to install the PHP extension library-Elasticsearch. Elasticsearch is an open source full-text search engine that helps users search and analyze large amounts of data more quickly. In PHP, Elasticsearch can be used through the elasticsearch-php library. The command to install the elasticsearch-php library using Composer is:

composer require elasticsearch/elasticsearch

After the installation is complete, just introduce the elasticsearch-php library into the PHP code.

Use PHP to implement Kibana search function

To use Kibana search function in PHP, you need to establish a connection with Elasticsearch through the elasticsearch-php library. Then, use the QueryBuilder class to build the search criteria and the Search class to perform the search. The following is a simple example:

require 'vendor/autoload.php';

use ElasticsearchClientBuilder;

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

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'content' => 'hello world'
            ]
        ]
    ]
];

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

print_r($response['hits']['hits']);

The above code first uses the ClientBuilder class to create an Elasticsearch client, and then uses the QueryBuilder class to build search conditions, where the query conditions are documents that match the string "hello world" in the content. . Finally, use the Search class to perform the search and output the results to the console.

Use PHP to implement Kibana analysis function

To use Kibana analysis function in PHP, you need to establish a connection with Elasticsearch through the elasticsearch-php library. Then, use the AggregationBuilder class to build aggregation conditions, and use the Search class to perform aggregation operations. The following is a simple example:

require 'vendor/autoload.php';

use ElasticsearchClientBuilder;

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

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'aggs' => [
            'top_10_tags' => [
                'terms' => [
                    'field' => 'tags',
                    'size' => 10
                ]
            ]
        ]
    ]
];

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

print_r($response['aggregations']['top_10_tags']['buckets']);

The above code first uses the ClientBuilder class to create an Elasticsearch client, and then uses the AggregationBuilder class to build aggregation conditions, where the aggregation conditions are grouped by tag fields and list the top ten occurrences name tag. Finally, use the Search class to perform the aggregation operation and output the results to the console.

Summary

This article introduces how to use PHP to implement the Kibana search and analysis engine. By using elasticsearch-php library, we can easily establish connection with Elasticsearch and build search and analysis conditions using QueryBuilder and AggregationBuilder classes. In addition, we also introduced the main features and application scenarios of Kibana. We hope this article can help everyone understand the principles and usage of Kibana.
