如何使用com组件的函数将多字段记录集存到多维数组里

Jun 23, 2016 pm 02:00 PM

php5.4使用com连接到phd数据库,此数据库特殊,表名,字段不好写,是honeywell的数据库。com查询返回多条记录,且多个字段,我想对某个字段进行算术运算,不知道如何操作,本人新手,上网查资料说是把记录集存到多维数组里,苦于不会php,请高手帮帮忙!谢谢!
我打个比方,查询0601班级的学生成绩,返回多条记录,每条记录包含:班级、学号、姓名、科目(语文)、成绩字段。如何使用com组件的函数将记录集存到多维数组里,单纯操作数组,我差不多会。
  
 $conn = new COM("ADODB.Connection"); 
  $connstr="...略了";
  $conn->Open($connstr);
  $starttime="2014-03-20 08:30:00";
  $sql="Select banji,sno,name,kemu,chengji FROM stu_cj WHERE  banji='0601' AND kemu='yuwen'";
  $stmt=$conn->Execute($sql);
下面如何使用com函数将记录集$stmt存储到多维数组,并操作数组


回复讨论(解决方案)

不知道phd数据库是什么
不过既然可以用 ADODB.Connection 连接,显然就没有什么大问题了
可以写作

$stmt = $conn->Execute($sql);while(! $stmt->eof) {  $res[] = arraay(    'banji' => $stmt->fields['banji']->value,     'sno' => $stmt->fields['sno']->value,    'name' => $stmt->fields['name']->value,    'kemu' => $stmt->fields['kemu']->value,    'chengji' => $stmt->fields['chengji']->value,  );  $stmt->MoveNext();}
Copy after login
总之与 asp 的写法基本一致

另外也可写用 obcd 函数组进行操作

非常感谢你的解答,学到了新知识

我又遇到个问题,经你指导成功将查询的记录集存储到数组中了,但如果多个班级,一个班级查询完得到一个数组,能再将班级名,和每个班级查询得到的数组一同存储在一个数组里?不知道我说明白没有,就是比如0601班级,和res[];0602班级和res[]。。。再存到数组里。班级不同得到的res不同,想把他们一起存到数组里,该如何做,又该怎么引用某一个值

array(
 '0601班级' => array();
 '0602班级' => array();
)

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
