手把手教你做关键词匹配项目（搜索引擎）---- 第一天，教你做----

第一天

收到需求，需求如下：

1. 收集关键词，构建关键词词库。

收到这个任务，第一想法，这还不简单吗？马上动手创建一个关键词录入界面，保存到数据库。第一步完成了，哈哈大笑了一天，没想到事情原来如此的简单。

数据库配置文件： config.php

<span>$database_host</span> = 192.168.1.1
<span>$database_user</span> =<span> xiaoshuaishuai
</span><span>$database_password</span> =<span> xiaoshuaishuai
</span><span>$database_charset</span> = "utf-8"

后台逻辑处理： keywords.php

<?<span>php

</span><span>include</span> "config.php"

<span>$keywords</span> = <span>$_REQUEST</span>["keywords"<span>];

</span><span>$con</span> = <span>mysql_connect</span>(<span>$database_host</span>,<span>$database_user</span>,<span>$database_password</span><span>);
</span><span>mysql_query</span>("SET NAMES '<span>$database_charset</span>'",<span>$conn</span><span>);
</span><span>mysql_select_db</span>("dict",<span>$conn</span><span>);

</span><span>foreach</span>(<span>$keywords</span> <span>as</span> <span>$keyword</span><span>){

      </span><span>//</span><span>save $keyword to database</span>
      
      <span>$sql</span> = "insert into keywords(word) values ('<span>$keyword</span>')"<span>;
      </span><span>mysql_query</span>(<span>$sql</span>,<span>$conn</span><span>);     
    
}

</span><span>mysql_close</span>(<span>$conn</span>);
