我已经制作了可以正常工作的自定义错误处理程序(见下文)。我添加了用于打印和记录错误的方法add() 。基本上它处理所有 PHP 注册的错误。
我尝试在类外部添加add_error()函数,以便开发人员更友好地使用添加错误。我遇到的问题是,我想从中获取正确的行和文件,但是使用debug_backtrace()似乎太复杂了。我的意思是..它可以解决问题,但是它返回了其他不必要的东西的数组,我尝试过滤数组,以返回文件和调用错误的行,但没有运气。
例如,如果我从load.php文件中调用$error->add(' test ',' test ') ,其中包含类文件error-handle.php,它会返回
C:\WebServer\www\projects\backend-framework\includes\error-handle.php:144:
array (size=2)
0 =>
array (size=7)
'file' => string 'C:\WebServer\www\projects\backend-framework\load.php' (length=52)
'line' => int 34
'function' => string 'add' (length=3)
'class' => string 'ErrorHandle' (length=11)
'object' =>
object(ErrorHandle)[1]
public 'count' => int 0
public 'last_error' => null
public 'errors' =>
array (size=0)
...
public 'debug' => int 1
public 'report_errors' => int 1
public 'log_errors' => int 1
'type' => string '->' (length=2)
'args' =>
array (size=2)
0 => string 'test' (length=5)
1 => string 'test' (length=5)
1 =>
array (size=4)
'file' => string 'C:\WebServer\www\projects\backend-framework\index.php' (length=53)
'line' => int 2
'args' =>
array (size=1)
0 => string 'C:\WebServer\www\projects\backend-framework\load.php' (length=52)
'function' => string 'require_once' (length=12)
test: test in C:\WebServer\www\projects\backend-framework\index.php on line 2
如您所见,它返回index.php而不是load.php
基本上,每当我调用add_error()或$error->add()时,我都需要获取调用函数的正确文件和行。可能通过使用带有一些高级过滤的debug_backtrace() 。
对于如何获得此结果的任何指导或想法,我将不胜感激。提前致谢!
