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
// You can also use arrays
$baz = array("value" => "foo");
echo "this is {$baz[value]} !"; // this is foo !
// 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
// Some people prefer passing multiple parameters to echo over concatenation.
echo This , string , was , made , with multiple parameters., chr(10);
echo This . string . was . made . with concatenation. . "
";
echo
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;
// Because echo does not behave like a function, the following code is invalid.
($some_var) ? echo true : echo false;
// However, the following examples will work:
($some_var) ? print true : print false; // print is also a construct, but
// it behaves like a function, so
// it may be used in this context.
echo $some_var ? true: false; // changing the statement around
?>
