Basic operations of ThinkPHP’s CURD, thinkphpcurd
Speaking of CURD, anyone who knows some SQL knows that it is adding, deleting, modifying, and checking. When building a business system, this is often indispensable. CURD, I have just come into contact with ThinkPHP recently. The flexibility of ThinkPHP is much easier to use than native PHP. Let me briefly introduce my learning experience.
To learn how ThinkPHP operates MySQL, you must first have MySQL, and then the PHP operating environment.
wamp can help you solve the configuration trouble. There is a lot of information about wamp, just Baidu.
The following is a brief introduction to the process of adding, deleting, modifying and checking in ThinkPHP.
1. Create a database and name it t_user.
The code is:
DROP TABLE IF EXISTS `t_user`; CREATE TABLE `t_user` ( `userid` int(11) NOT NULL, `username` varchar(25) DEFAULT NULL, `usersex` varchar(6) DEFAULT NULL, `userage` int(6) DEFAULT NULL, PRIMARY KEY (`userid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Create a project, name it thinkPHP_Text, and import the thinkphp core package.
Configure the index.php file.
Start the project and automatically generate the directory. As shown below:
2. Regarding the add() operation of thinkphp.
Create an action file for index, name it IndexController.class.php, and write a function insertUser(). In the control layer, you need to get the value passed by the frontend.
<span>/*</span><span>* * 添加用户信息 * 编码时间:2015-05-28 </span><span>*/</span> <span>public</span> <span>function</span> insertUser(<span>$id</span>,<span>$name</span>,<span>$sex</span>,<span>$age</span><span>){ </span><span>$this</span>->db(1,"DB_CONFIG1")->db(1<span>); </span><span>$condition</span> = <span>array</span>(<span>//</span><span>定义要添加的数据,放在一个数组里,命名为$condition</span> 'userid' => <span>$id</span>, 'username' => <span>$name</span>, 'usersex' => <span>$sex</span>, 'userage' => <span>$age</span>,<span> ); </span><span>$addInfo</span> = <span>$this</span>->db(1,"DB_CONFIG1")->add(<span>$condition</span>);<span>//</span><span>执行sql语句,insert</span> <span>if</span>(<span>$addInfo</span><span>){ </span><span>header</span>("Location: http://localhost/thinkPHP_Text/index.php"<span>); } </span><span>echo</span> <span>$this</span>->getLastSql();<span>//</span><span>调试用,输出sql语句</span> <span>return</span> <span>$addInfo</span><span>; } </span><span>/*</span><span>*</span>
In the model layer, remember the naming method. In this configuration, it is named UserModel.class.php, and corresponds to:
<span> 1</span> <span>/*</span><span>* </span><span> 2</span> <span> * 添加用户信息 </span><span> 3 </span><span> * 编码时间:2015-05-28 </span><span> 4</span> <span>*/</span> <span> 5</span> <span>public</span><span> function insertUser($id,$name,$sex,$age){ </span><span> 6</span> $<span>this</span>->db(<span>1</span>,<span>"</span><span>DB_CONFIG1</span><span>"</span>)->db(<span>1</span><span>); </span><span> 7</span> $condition = array(<span>//</span><span>定义要添加的数据,放在一个数组里,命名为$condition</span> <span> 8</span> <span>'</span><span>userid</span><span>'</span> =><span> $id, </span><span> 9</span> <span>'</span><span>username</span><span>'</span> =><span> $name, </span><span>10</span> <span>'</span><span>usersex</span><span>'</span> =><span> $sex, </span><span>11</span> <span>'</span><span>userage</span><span>'</span> =><span> $age, </span><span>12</span> <span> ); </span><span>13</span> $addInfo = $<span>this</span>->db(<span>1</span>,<span>"</span><span>DB_CONFIG1</span><span>"</span>)->add($condition);<span>//</span><span>执行sql语句,insert</span> <span>14</span> <span>if</span><span>($addInfo){ </span><span>15</span> header(<span>"</span><span>Location: http://localhost/thinkPHP_Text/index.php</span><span>"</span><span>); </span><span>16</span> <span> } </span><span>17</span> echo $<span>this</span>->getLastSql();<span>//</span><span>调试用,输出sql语句</span> <span>18</span> <span>return</span><span> $addInfo; </span><span>19</span> }
This is the core code of the add operation.

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
