PHP error handling and exception handling

1. Set your own error-handling function

Trigger_error () captures user-level errors. Set_error_handler () user-defined error handling function.

2. Catching exceptions

Catching exceptions of course with try{

A function with an exception is placed here, no exception, code continues execution, exception is triggered, an exception is thrown

}catch () {

}

Of course, the exception handling class used in the code is thinkphp, Throw_exception is the thinkphp throw exception function

In addition to the PHP error mechanism to add:

the value above (numeric or symbolic) is used to create a bits mask, To create the error message to report. You can use bitwise operators to combine these values or to mask some types of errors. note that in  php.ini , only ' | ', ' ~ ', '! ', ' ^ ' and ' & ' will parse correctly.
