With this customErrorMessage method, the output will be something like “Error on line (line number) in file (file name): Cannot divide by zero”, and it will give more detailed information in case we need to debug the exception. I have now implemented the try/catch pair and no longer have the script stop. 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. The point is that if you only use filegetcontents () on a file/url that doesn’t exist, php throws a EWARNING - to avoid that (and as good programming practice) test that the file exists first.
