## Why is this an issue?

`echo` can be called with or without parentheses, but it is best practice to leave parentheses off the call because using parentheses with multiple arguments will result in a parse error.

### Noncompliant code example

    echo("Hello");  // Noncompliant, but it works
    echo("Hello", "World"); // Noncompliant. Parse error

### Compliant solution

    echo "Hello";
    echo "Hello","World!";
