在js中 现在得不到json.php查询数据的 (10 20 30 40)值 ,请教 怎么取到值 ,先谢谢了!

已解决

1、把从数据库取到的结果集 放到view层中,并用赋值不同的变量
2、再在js中将js的变量 =上边的变量

$result = array();
   foreach ($query as $v){

    $result[] = $v->data;
    //echo $v->data; 
   echo "
";
   }
 
 ?>

<script> <br /> window.onload = function() { <br /> var _data="<?php echo $ result[3];?>"; <br /> var R = Raphael("map", 800, 500); <br /> var fillcolor = "#FFFFFF"; var beijing = "#FF8F59"; var beijing1 = "602"; var beijing2 = _data; <br /> 。。。。。。。。。。。。。。 <br /> } <br /> </script>

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.
