How can missing argument errors be avoided in PHP functions?

Missing argument errors in PHP functions can be avoided by providing default values for the arguments in the function definition. By setting default values, the function can still be called without all arguments being passed, preventing errors. This ensures that the function will work even if some arguments are missing. 

function exampleFunction($arg1 = 'default1', $arg2 = 'default2') {
    // Function code here
}
