What are common errors when defining and calling functions in PHP scripts?

One common error when defining and calling functions in PHP scripts is not using the correct syntax or not providing the required parameters when calling the function. To solve this, make sure to define the function with the correct syntax and specify any required parameters when calling it. 

// Incorrect function definition
function myFunction {
    echo "Hello World!";
}

// Correct function definition
function myFunction() {
    echo "Hello World!";
}

// Incorrect function call without required parameter
myFunction(); // This will result in an error

// Correct function call with required parameter
myFunction($parameter); // Make sure to provide the required parameter
