Error trapping in PHP

Exception Capture for PHP

? ? ? Always different or PHP try catch how to use

?

??? Look at the documentation to say that a new exception is needed to catch it.

?

? ? ? What if you need to catch the lower bound of the array, or if the parameter passed by the method is not correct?

?

? ? ? Fortunately, PHP provides a Set_error_handler function that allows users to capture these exceptions themselves, such as:

 
 GetMessage ();} function Exception_error_handler ($errno, $errstr, $errfile, $errline) {    throw new errorexception ($errstr, 0, $errno , $errfile, $errline);}

?

?

??? So you can catch an exception.
