Syntax: Nowdoc syntax

echo <<<'EOD'
Example of string spanning multiple lines
using nowdoc syntax. Backslashes are always treated literally,
e.g. \\ and \'.
class foo
    public $foo;
    public $bar;

    function __construct()
        $this->foo = 'Foo';
        $this->bar = array('Bar1', 'Bar2', 'Bar3');

$foo = new foo();
$name = 'MyName';

echo <<<'EOT'
My name is "$name". I am printing some $foo->foo.
Now, I am printing some {$foo->bar[1]}.
This should not print a capital 'A': \x41
class foo {
    public $bar = <<<'EOT'
  • Nowdocs are to single-quoted strings what heredocs are to double-quoted strings.
  • A nowdoc is specified similarly to a heredoc, but no parsing is done inside a nowdoc.
  • The construct is ideal for embedding PHP code or other large blocks of text without the need for escaping.
  • It shares some features in common with the SGML &lt;![CDATA[ ]]&gt; construct, in that it declares a block of text which is not for parsing.
  • A nowdoc is identified with the same <<< sequence used for heredocs, but the identifier which follows is enclosed in single quotes, e.g. <<<'EOT'.
  • All the rules for heredoc identifiers also apply to nowdoc identifiers, especially those regarding the appearance of the closing identifier.
