Differentiating Between Exception and Error in PHP
In PHP, exceptions and errors are both mechanisms for handling unexpected or exceptional situations that occur during the execution of a script. However, they differ in their purpose, handling, and the types of situations they address.
Exceptions
Exceptions are user-defined or built-in classes that represent exceptional conditions or errors that can occur during the execution of a script.
Exceptions are typically used for handling anticipated or expected errors, such as invalid input, file not found, or database connection failures.
Exceptions are handled using a try-catch block, where the code that might throw an exception is placed inside the try block, and the catch block is used to handle the exception.
If an exception is thrown and not caught, the script will terminate, and an error message will be displayed.
Exceptions can be caught and handled gracefully, allowing the script to continue executing or provide alternative actions.
