请问,php如何打印出从服务器返回的原始json
请教,php怎么打印出从服务器返回的原始json?
我用一个php从服务器请求,服务器返回了标准格式的json,然后赋值到$a,我现在想把原始json数据打印出来,怎么办?
echo只显示一个Array,print,prinf是空,print_r是显示出了,但已经不是json格式的数据了。
------解决方案--------------------
显然$a存储的不是json字符串,而是经过json_encode()后的PHP的数组。
相应的,你可以echo json_decode($a);
------解决方案--------------------
echo json_encode($a);即可,$a明显是decode过的字符串……
------解决方案--------------------
你使用了新浪的SDK,而SDK的作用即在开发便捷。虽然/statuses/home timeline的返回格式是json,但还是经过了SDK内部处理。
PHP不能直接操作json字符串,因此这个SDK帮你预先把json转换为PHP的数组。
------解决方案--------------------
- PHP code
$ch = curl_init(); $ch = curl_init($url) ; curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); $out = curl_exec($ch); $out = trim($out); curl_close($ch); $out = json_decode($out, true); var_dump($out);<br><font color="#e78608">------解决方案--------------------</font><br>异步直接用ajax不就行了吗,对json支持很好

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,

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.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
