php里如何在函数中获取调用此函数的当前文件名
在php获取当前文件名很简单,使用__FILE__
常量就是了。但是如果我定义了一个通用函数,而这个每次被调用的时候就要获取当前调用它的是哪个文件,应该怎么办呢?
<code><?php // 这是lib.php function get_current_file() { // ... do something } </code></code>
<code><?php // 这是action.php echo get_current_file(); </code></code>
也就是如上的效果,我调用get_current_file
时要获得当前的调用文件比如action.php
。
这只是个例子,真正使用的时候我不会单纯的去获取文件名,而是要配合一些逻辑,不过这是最重要的一步。

可以试下http://cn2.php.net/manual/zh/function.debug-backtrace.php
里面有个和你要的效果类似的例子,给你摘下如下
<?php function get_caller_info() { $c = ''; $file = ''; $func = ''; $class = ''; $trace = debug_backtrace(); if (isset($trace[2])) { $file = $trace[1]['file']; $func = $trace[2]['function']; if ((substr($func, 0, 7) == 'include') || (substr($func, 0, 7) == 'require')) { $func = ''; } } else if (isset($trace[1])) { $file = $trace[1]['file']; $func = ''; } if (isset($trace[3]['class'])) { $class = $trace[3]['class']; $func = $trace[3]['function']; $file = $trace[2]['file']; } else if (isset($trace[2]['class'])) { $class = $trace[2]['class']; $func = $trace[2]['function']; $file = $trace[1]['file']; } if ($file != '') $file = basename($file); $c = $file . ": "; $c .= ($class != '') ? ":" . $class . "->" : ""; $c .= ($func != '') ? $func . "(): " : ""; return($c); }

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,
