![]() The try/catch is just a complicated if statement, and I dont see much use for it if youre trying to use instead of an if statement. This way, we can add custom functionality, or throw different types of exceptions to be handled in different ways. If anything goes wrong when you are reading a file, your code should be throwing some type of Exception which describes the problem. I think thats because exception handling was introduced in PHP5 as one of their OOP features. With this customErrorMessage method, the output will be something like âError on line (line number) in file (file name): Cannot divide by zeroâ, and it will give more detailed information in case we need to debug the exception. The getLine() method returns the line number where the exception is thrown and the getFile() method returns the file name where the exception is thrown, which allows us to have a more informative error message. To display different messages you can either create lots of functions or you can pass a variable in to the function when you call it. ![]() If an exception is thrown inside the try block, the script will jump to the corresponding catch block. Its best practice to catch exceptions as close to the point theyre thrown to avoid catching unrelated exceptions of the same type. The try block contains the code that may throw an exception, and the catch block contains the code that will handle the exception. We throw an Exception because the file in question should exist. The basic syntax for handling exceptions in PHP is the try-catch block. In the example above, we throw an Exception if we fail to open the file in question.
