This is the base test that there are no any try/ catch blocks at all. try/multiple catch, throw exception: Catch the Exception from last catch block.try/ catch, throw exception: Catch the Exception from first catch block.

try/multiple catch, no exceptions: Similar to #3, but with multiple cascading catch blocks. Custom exception classes are useful when you have requirements for custom error handling, for example logging error in database etc. When an exception is thrown, the code following it will not be executed, and PHP will try to find the matching 'catch' block.

try/ catch, no exceptions: Use a try/ catch block, but do not throw any Exception.

So you didnt test try-catch performance, but handling exceptions performance, which of course is much slower.

But if you have only try-catch block, and no exception is thrown, then code is not any slower as jmucchiello tested. try/ catch, return within try block: Return a value from inside a try block. Loop throwing exception costs more, as it actually throws an exception.No try/ catch: Test without any exception handling at all.But if you cant update the classes, in PHP 7, you can catch. Then, you can catch that exception instance. First, if you are able to modify these exceptions, you should make them extend a common base class or implement a common interface. In the benchmark, we will take a look at 6 test cases: Is it possible to catch all errors in Blazor Server like in MVC 5 in global.asax on ApplicationError We are trying to integrate the ErrorBoundary component. And if you find yourself catching multiple exceptions, there are two solutions. This benchmark is meant to compare the relative performance impact of using Exceptions at all, and how it progressed over PHP versions. It is highly unlikely that use of Exceptions is the bottleneck of any application. Note that Exceptions with throw keyword, or the use of try/ catch blocks has a very small execution time. This article tries to discover the performance impact of handling and throwing exceptions. In PHP 8.0, several of PHP internal functions will throw standard TypeError and ValueError exceptions, which means you will be seeing more and more exceptions and exception handling in PHP code. PHP provides various capabilities to use Exceptions in PHP code, such as global exception handlers, basic try/ catch syntax, cascaded and combined catch syntax, catching exceptions just with its type, and the finally blocks. Exceptions in programming languages provide a way for the application code to raise and handle exceptional situations, and PHP language is not an exception.
