如何正确运用PHP json_encode函数进行中文转换_PHP

Jun 01, 2016 pm 12:20 PM

JSON

json_encode 和 json_decode

这两个函数的具体用法 网上有很多相关的文章 ,本文主要介绍 用json_encode 时中文无法转换的解决方案,本文假设文件所用的编码为gb2312;

先写出所需的数组

$json = array (
0 =>
array (
'id' => '13',
'name' => '乒乓球',
),
1 =>
array (
'id' => '17',
'name' => '篮球',
)
)
?>

如果直接用PHP json_encode函数

echo json_encode($json);
?>

结果为:

[{"id":"13","name":null}
,{"id":"13","name":null}]
?>

可以看到汉字没有被转义都为null,这是因为json仅仅转义encoding编码(类似于:%B0%AE),故上面语句应该先转换编码

foreach ($ajax as $key=>$val)
{
$ajax[$key]['name'] =
urlencode($val['name']);
}
echo json_encode($json);
?>

客户端js代码

用上面的代码js会报错 说编码不符合标准

原因是因为js 中decodeURI 仅仅支持utf8 转码。所以 ,PHP json_encode函数的代码应该为下面的代码

foreach ($ajax as $key=>$val)
{
$ajax[$key]['name'] =
urlencode(iconv('gb2312',
'utf-8',$val['name']));
}
echo json_encode($json);
?>

以上就是使用PHP json_encode函数在实际操作中出现问题的解决方法。

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.
