php中如何同时执行两个不同的insert语句
class SqlTool{
public $link;
public $hostName="localhost";
public $userName="root";
public $userPwd="";
public $db_Name="qlzx";
public function execute_dml($sql){
$res=$this->link->query($sql) or die($this->link->error);
if(!$res) return 0;
else{
if($this->link->affected_rows>0) return 1;
else return 2;
}
}
}
$sqlTool=new SqlTool();
$sql="insert into customerinfo values(null,'{$ci->getEmail()}','{$ci->getPwd()}',now())";
$sql.="insert into customerdetailinfo values(last_insert_id(),'{$cdi->getName()}','{$cdi->getTelphone
()}','{$cdi->getMovePhone()}','{$cdi->getAddress()}')";
$sqlTool->execute_dml($sql);
?>
这样执行语句能否成功?
------解决方案--------------------
不能,至少你SQL语句之间还应该有个分号来隔开。
我更好奇的是为什么你会有这么奇怪的需求,分开执行不仅方便排错,而且安全
------解决方案--------------------
用事务
------解决方案--------------------
分开写,费不了多少事。
last_insert_id() 这么做完全没必要,ID是自增的,那么就不需要你去指定。任何数据库的设计者都会考虑到自增键可能出现的任何问题,并在开发阶段就能解决。
------解决方案--------------------
不能!
一次只能执行一条 SQL 指令,这是 php 内置的 防范SQL攻击 的措施,不要试图突破他
分开来执行也是一样的,只要数据库连接没断开过
------解决方案--------------------
用事务处理。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
