How important is correct syntax, such as capitalization, in PHP function names?

Correct syntax, including capitalization, is crucial in PHP function names because PHP is a case-sensitive language. This means that if the function name is not spelled correctly or if the capitalization is incorrect, PHP will not recognize the function and will throw an error. To ensure proper syntax, always use the correct capitalization when defining and calling PHP functions. 

function myFunction() {
  // function implementation here
}

myFunction();
