Outputting blocks of text or HTML
The normal way of outputting text is
echo 'Here is some text';
or
echo "I am $age years old";
However when you want to output a lot of text that may contain single or double quotes, the "heredoc" shown below is more elegant
echo <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
EOD;
