php implements the method to determine whether the access source is a search engine robot, the source search engine
This article describes the example of php to determine whether the access source is a search engine robot . Share it with everyone for your reference. The specific analysis is as follows:
Many times we need to identify the source of website visitors and perform different actions for real users and search engines. Then we first need to determine whether it is a search engine.
The PHP judgment method is very simple. You can identify it by filtering the $_SERVER['HTTP_USER_AGENT'] parameter. The following is an excerpt of the relevant source code of an open source program:
private function getRobot() { if (empty($_SERVER['HTTP_USER_AGENT'])) { return false; } $searchEngineBot = array( 'googlebot'=>'google', 'mediapartners-google'=>'google', 'baiduspider'=>'baidu', 'msnbot'=>'msn', 'yodaobot'=>'yodao', 'youdaobot'=>'yodao', 'yahoo! slurp'=>'yahoo', 'yahoo! slurp china'=>'yahoo', 'iaskspider'=>'iask', 'sogou web spider'=>'sogou', 'sogou push spider'=>'sogou', 'sosospider'=>'soso', 'spider'=>'other', 'crawler'=>'other', ); $spider = strtolower($_SERVER['HTTP_USER_AGENT']); foreach ($searchEngineBot as $key => $value) { if (strpos($spider, $key)!== false) { return $value; } } return false; } public function isRobot() { if($this->getRobot()!==false) { return true; } return false; }
I hope this article will be helpful to everyone’s PHP programming design.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
