Error handling refers to the process of managing errors that arise during the execution of a program.
If any errors appear in the code, you identify and fix them to ensure the program runs smoothly without issues.
With the help of error handling, we can detect, analyze, and fix errors to make the program error-free.
There are many types of errors, which are the following:
Parse errors are errors that occur in a program due to syntax mistakes, semicolon mistakes, mismatched parentheses, incorrect code structure, or other syntax-related issues.
We must write the program before running it. You should check the mistakes; then, we can avoid the errors.
Fatal errors are errors that prevent the script from running. They are the most critical errors. In the program, a function you have called may not exist, or there could be a PHP file that you want to include in the program, but that file is not present.
When you write a program, errors can occur, and a warning message will be displayed. For example, if you write a program to divide 4 by 2 but mistakenly divide by zero instead of 2, this warning message will not stop the program from executing the remaining code.
This error does not stop the script from executing. This error is a minor issue. This error occurs when PHP detects something unexpected, such as when an undefined variable is present.
