To show warnings and notices, the parameter for the error reporting function will be “E_WARNING | E_NOTICE”. error_reporting(E_WARNING) įor a developer, showing warnings and hiding errors is just as simple as adding a single line of code. In case these warnings cause a lot of errors, then it would be more practical to hide the errors and just show what the warning messages are.
