     language construct) so you are not required to use parentheses
     with it. In fact, if you want to pass more than one parameter
     to echo, you must not enclose the parameters within parentheses.

echo "Hello World";

echo "This spans
multiple lines. The newlines will be 
output as well";

echo "Escaping characters is done \"Like this\".";

//You can use variables inside of an echo statement
$foo = "foobar";
$bar = "barbaz";

echo "foo is $foo"; // foo is foobar

// Using single quotes will print the variable name, not the value
echo 'foo is $foo'; // foo is $foo

// If you are not using any other characters, you can just echo variables
echo $foo;          // foobar
echo $foo,$bar;     // foobarbarbaz

echo &#60;&#60;&#60;END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
END;

// Because echo is not a function, following code is invalid. 
($some_var) ? echo('true'): echo('false');

// However, the following examples will work:
($some_var) ? print('true'): print('false'); // print is a function
echo $some_var ? 'true': 'false'; // changing the statement around
