请问一下php能不能像java那样打印错误堆栈信息到错误日志?
同题,如果可以大概操作步骤是什么?或者有什么相关资料?谢谢。

之前的回答有问题,清除了。
就像楼下说的,PHP 确实不会输出错误堆栈,但通过函数,还是能够获取到错误堆栈的。
function getBacktrace() { ob_start(); debug_print_backtrace(); return ob_get_clean(); }
调用上面这个函数取得错误堆栈,再用 file_put_contents('log_path', FILE_APPEND);
写入日志文件即可。
还有一个办法:为 PHP 安装 xdebug 扩展
windows 下的安装方法:http://www.cnblogs.com/qiantuwuliang/archive/2011/01/23/1942382.html
安装好后,修改 php.ini
log_errors = On error_log = "F://path/php_error.log"
开启PHP的本身的日志记录,只会记录PHP本身出错时的日志,如各种语法错误,警告之类的。@rjbj 想要的应该是在业务中打日志以及出错了迅速找到出错的地方在框架中所处的位置。 如果你不用框架的话,要实现这样的功能,就要自已结合PHP的异常处理和日志类库来实现,用框架的话几乎所有的全堆栈框架都会支持的。
你可以看下 debug-backtrace
和 debug-print-backtrace.php
两个函数:

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,
