正则表达式 - php 可以匹配"函数","类"么?求实现
<code><?php $str = <<<EOT function a(){ echo 'fun a'; } function b($b){ echo 'b'; } function c($c){ if($c == 1){ echo 'c1'; }else{ echo 'c2'; } } EOT; </code></code>
要到达的效果如下:
将字符串$str里面的三个函数分离出来存到数组里面去,有什么好的兼容性高的正则匹配方法么?(类同理)
谢谢大家
回复内容:
<code><?php $str = <<<EOT function a(){ echo 'fun a'; } function b($b){ echo 'b'; } function c($c){ if($c == 1){ echo 'c1'; }else{ echo 'c2'; } } EOT; </code></code>

请你先说明这样做的意义在哪里,你为什么要这样呢?
另外根据你的问题我提供一些资料,希望能帮到你
php的创建匿名函数 create_function
get_defined_vars返回由所有已定义变量所组成的数组
如果是正则表达式,需要用到正则表达式的平衡组的概念。
如果你的str中比较规整 没有function嵌套,function间没有别的语句的话,可以直接用字符串拆分的方法。
正则是一个"兼容性"(健壮性)非常差的东西, 如果不限麻烦的化可以使用PHP-Parser.

PHP-Parser 提取 AST, 然后通过AST反向生成代码. (这里需要你自己遍历AST)

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.

What are the magic methods of PHP?
