--------------------------------------------------------------------------------
1 | a little php class which can provide you an easy way to handle errors (even non recoverable errors like E_ERROR, E_PARSE, E_CORE_ERROR, E_COMPILE_ERROR)
2 | it wraps the error to an ErrorException instance and throws the exception(for catchable errors) or calls the default exception handler (for fatal errors)
3 |
4 | if you create an instance from PHP_Error_Handler without any arguments, it will call the global error/exception handler method, if it's available.
5 |
6 | the first argument can be a callable variable, if set, that will be called instead of the global error/exception handler.
7 |
8 | the second argument will be interpreted as a boolean value: if is set to true, the errors will be converted to ErrorException and passed to the exception handler (either to the global, or the one passed as argument).
9 |
10 | the third argument will be interpreted as a boolean value: if is set to true, then the script will overwrite the global error handler if is set. (only required if $errorsToException is set to true and another error handler was set with set_error_handler)
11 |
12 | BEWARE: you cannot continue the execution of your script on such errors, but with this script, you can gracefully terminate
13 |
14 | see the src/demo.php for examples
15 |
16 | Requirements: php >= 5.2.6
