This article introduces a piece of code that uses PHP to record search engine keywords. It is a good reference for beginners.
Use PHP to record search engine search keywords. The code is as follows: <?php /** * 记录搜索引擎搜索关键词 * edit by bbs.it-home.org */ //搜索来源 $rfr = $_SERVER['HTTP_REFERER']; //if(!$rfr) $rfr='http://'.$_SERVER['HTTP_HOST']; if($rfr) { $p=parse_url($rfr); parse_str($p['query'],$pa); $p['host']=strtolower($p['host']); $arr_sd_key=array( 'baidu.com'=>'word', 'google.com'=>'q', 'sina.com.cn'=>'word', 'sohu.com'=>'word', 'msn.com'=>'q', 'bing.com'=>'q', '163.com'=>'q', 'yahoo.com'=>'p' ); $keyword=''; $sengine=$p['host']; foreach($arr_sd_key as $se=>$kwd) { if(strpos($p['host'],$se)!==false) { $keyword=$pa[$kwd]; $sengine=$se; break; } } //写入搜索日志 $sql="insert into visit_log(domain,key_word,ct)"; } ?> The code is very simple, mainly to give you an idea: By analyzing the source of the search engine, intercepting the relevant parameter values in the URL, then analyzing the keywords, matching the relevant searches, and recording them in the search log database.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
