# => '$String'
$sgl_quotes = '$String';

$dbl_quotes = "This is a $sgl_quotes.";

$escaped   = "a \t tab character.";

# => a slash and a t: \t
$unescaped = 'a slash and a t: \t';

$str = "foo";

// Uninterpolated multi-liners
$nowdoc = <<<'END'

$str

Manipulation

$s = "Hello Phper";
echo strlen($s);       # => 11

echo substr($s, 0, 3); # => Hel
echo substr($s, 1);    # => ello Phper
echo substr($s, -4, 3);# => hpe

echo strtoupper($s);   # => HELLO PHPER
echo strtolower($s);   # => hello phper

echo strpos($s, "l");      # => 2
var_dump(strpos($s, "L")); # => false
