Question
solr+php How to install, configure and use
Solution 1:
solr provides http request query interface. The client obtains data in json, xml and other data formats by triggering http requests, and parses and displays the data. Generally, various languages will have encapsulated client plug-ins, such as Java's solrj, Python's solrpy, and PHP's php-solr-client, which can be indexed and queried according to the provided API. As for the installation and configuration of solr, you can read the solr cookbook.
Solution 2:
I want to make the php program use solr search. I was worried at first
I don’t know how What to do with java?
How to create an index for the search system?
How to write code in php?
solr is written in java. It is a server program with a management interface and provides http interface.
In addition to the configuration file, there is no need to write java code. PHP has solr extensions.
So, it is quite simple. 1. Install solr and verify You have installed it
Refer to Installing Solr5.3 under CentOSsolr5.3 is already a separate server, including the web management background, so it is very good
Just make sure your linux has jdk
Download the solr5.3 package directly. Apache Download Mirrors
Be sure to download solr5.3.tgz like this. Do not download the src package, and then unzip it to get a directory like solr5.3
The two most critical points for installation 1. You can use it without unzipping. There is a directory in the solr directory. The install script needs to be run, and the data directory must be specified (to store the index) 2. Solr has a concept of core, which can be understood as db in the database. You can create a core. This also has a script, but you must ensure that the data directory has the permissions of the solr user.
# solr-5.3.0/bin/install_solr_service.sh solr-5.3.0.tgz -d /data/solr -i /usr/local
-i indicates where you installed the solr server
# su - solr -c "/usr/local/solr/solr/bin/solr create -c corename
service solr start Start the service
http://yourip::8983/solr This is management Interface
2, design your own search indexhttp://yourip::8983/solr This is the management interface, select the core you createdJust focus on add Documents and query, add index in one thing Query one thing, very easy to understand
add Documents interface, there are already examples, two fields id and title are indexed, you can change the data submission
q=title:a* to query title
It’s easy to understand after playing a few times for
Now there are id and title. I want to add a field of my own, what about type?
Go to the data directory and grep "title", and find the configuration items of id and title, similar to :
Please fill in the type as shown below
service solr stop/start restart the service
Then q= title:xx 2 studies, basically can create data, find the data and now write a php program to complete these functions
Reference: PHP: Solr - Manual
SolrInputDocument input document
SolrQuery This is to build the search conditions Go directly to the program:
class Search { private $client; public function __construct() { $options = [ 'hostname' => 'localhost', //solr服务器的ip 'path' => 'solr/corename', //这个解决core的问题,corename就是你的core 'wt' => 'json', ]; $this->client = new \SolrClient($options); } public function addIndex($id, $type, $content) {//加索引的函数 $doc = new \SolrInputDocument(); $doc->addField('id', $type . "." . $id); //保证id唯一我把type加上了 $doc->addField('type', $type); $doc->addField('title', $content); $client = $this->client; $updateResponse = $client->addDocument($doc); $client->commit(); //一定要commit才能立即生效 $ret = ($updateResponse->getResponse()); if ( isset($ret->responseHeader['status']) ) { return $ret->responseHeader['status'] == 0?true:false; } return false; } public function search($key, $type=0, $page=0, $limit=15) { $query = new \SolrQuery(); $query->setQuery('title:' . $key . "*"); //这个是设置keyword $query->setStart($page); //分页的 $query->setRows($limit); if($type) { $query->addFilterQuery('type:' . $type); //用到fq了 } $query->addField('id')->addField('title')->addField('type'); //这里是你要查哪些字段 $client = $this->client; $query_response = $client->query($query); $response = $query_response->getResponse(); $response = ($response->response); if ( is_array($response->docs) ) { foreach($response->docs as &$doc) { $id = explode(".", $doc->id); if( isset($id[1]) ) { $doc->id = $id[1]; } $doc->type = isset($doc->type[0])?$doc->type[0]:''; } } return ($response); } }

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
