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();
}
Copy after login

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"
Copy after login

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。

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?

你可以看下 debug-backtrace 和 debug-print-backtrace.php 两个函数: http://www.php.net/manual/en/function.debug-backtrace.php http://www.php.net/manual/en/function.debug-print-backtrace.php
