Although PHP 7 provides both error types and exceptions, let’s look at the Throwable interface first. The Error and Exception Throwable Implement Dock classes are the basis for everything that can be thrown with the Throw statement. It has only one element notification exception, cannot be implemented directly in userspace styles, only by extending the exception class. In addition, it provides a single link to detect both types of errors in a statement:
Exception
Error Exception
Errors
ArgumentCountError
Arithmetic error
Confirm error
DivisionByZeroError
Compilation error
Parse error
Input error

Error What?
What are the functions of error handler?
error detection.Error message.Repair.
In earlier versions of PHP, errors were handled differently than exceptions. An error is something that happened throughout the engine, if it wasn't fatal it could be handled with a custom function.
What are the functions of error handler?
The problem was that in addition to errors that the last custom error handler couldn't handle, there were usually a few fatal errors. This meant that not everyone could gracefully handle fatal errors in PHP. There were a few side effects that were a problem, such as context loss, rendering destructors not being called, and management complexity. In PHP 7, fatal errors are now exceptions and can potentially be handled very easily. Fatal inconsistencies cause an error exception. You don't need to handle fatal errors with an error handler.
Here is an example of a fatal error in PHP 7.1. Note that a non-fatal error was definitely not caught.
getmessage();
This software will generate an error message if an attempt is made to access an invalid variable. Attempting to call a function that doesn't actually exist would result in a malicious error in previous versions of PHP, but as of PHP 7.1 it can be caught. Here is the output of the script:
Note: variable not set: someNotSetVariable on line 3Artificial call error: for undefined function someNoneExistentFunction()
PHP has a property of constants used in relation to errors. These constants are used when PHP is configured to hide or show certain class errors.
E_DEPRECATED. The translator issues this warning when you use a deprecated language feature. In any case, the recording will continue without errors.
E_STRICT - Similar to E_DEPRECATED, indicates that you are using a language feature that is not currently standard and may not work in the future. The script must beAllow work without errors.
E_PARSE - Your syntax cannot be parsed, so your script will not run. Script conversion doesn't even start.
