``++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

[source,php]
----
echo("Hello");  // Noncompliant, but it works
echo("Hello", "World"); // Noncompliant. Parse error
----


== Compliant Solution

[source,php]
----
echo "Hello";
echo "Hello","World!";
----
