事务怎么捕捉操作数据库出错
多条语句操作数据库 全部成功执行才提交事务 否则回滚
比如 insert 一句成功执行
update 语句执行无错，但更新影响到的记录为0，此时是不要回滚的
如下，$uname 值与数据库中 uname 值相同
$res 就返回0 事务失败
<code>$db->query("BEGIN");$sql="update member set uname=$uname where id=$id";$res=$db->query($sql); if($res){ $db->query("COMMIT"); errAlert("成功","list.php");}else{ $db->query("ROLLBACK"); errAlert("失败,发生错误",$theUrl);} $db->query("END");</code>

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou 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.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect 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.
