Home Backend Development PHP Tutorial CI $this->load->view不能循环调用

CI $this->load->view不能循环调用

Jun 23, 2016 pm 01:41 PM

项目中遇到的一点问题,获取视图的模板并存入数据库,简单描述一下:
1、查询出id
2、循环调用视图

3、create_static_temp_page这个方法会调用视图,取出视图的内容,并将内容存入数据库


问题:
数据库查询到的id明显是多个,循环调用这个方法,经过测试,程序每次运行到$this->db->view这一步就“停止”了,这里停止并不是return或者exit,因为能把视图的内容存入数据库,但是只循环一次,因为我在循环里打印$r['id']只输出一次。

网上找到的一点思路:CI 的视图类$this->db->view会在调用完毕后,运行ob_end_flush(),但这跟循环一次有什么关系?

寻求各位的帮助

看起来逻辑上没有问题。只能一步步调试了。
你看看$arr里有几个元素?

$arr 是一个二维数组
array (size=2)
  0 => 
    array (size=1)
      'id' => string '88' (length=2)
  1 => 
    array (size=1)
      'id' => string '89' (length=2)

我没有好办法了,只能一步步跟踪,看看什么时候停止了,为什么停止了。
对了,记得打开错误信息,可能是出错了,导致程序中止了。

自己调试一下,看你的视图做了什么。

 CI的load view方法使用ob缓存的方法将内容输出到屏幕,$thi->load->view('',true)的第二个参数决定了是否是否使用ob,每次在调用完之后都会执行ob_end_clean(),需要循环调用load view方法的你可以自己再思考思考,主要是ob缓存的一些问题

第三个参数。。。

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
