function indeup($sql){
$c=mysql_connect("localhost","root","123456");
mysql_select_db("test");

return mysql_fetch_array($result);
}else{

}
}
echo indeup("insert into test_user (username,password) values('qqqqqq','qqqqqq')");
有警告错误 Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in D:\kisshc\apache\htdocs\mysql\index.php on line 15
回复讨论(解决方案)
mysql_query() 仅对 SELECT,SHOW,EXPLAIN 或 DESCRIBE 语句返回一个资源标识符,如果查询执行不正确则返回 FALSE
看看你的$sql是什么语句
array mysql_fetch_array ( resource $result [, int $ result_type ] )
$result resource 型,是一个由mysql_query 产生的结果集
而你的sql是insert语句,mysql_query() 执行后只返回true或者false。
嗯谢谢你的回答 可是 return mysql_query($sql,$this->ID); 没有返回的 true或false

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.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
