As a newbie, I have been advised to preferably use heredoc compared to too many nested codes (see Unexpected T_ELSE in php code).
But I can't manage to understand if there is a significant difference between heredoc and nowdoc.
What would be the advantages for heredoc and nowdoc compared to the other one that would be important for a newbie to understand (i.e. not very minor advantages but important to understand for me).
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.
In other words:
$foo = 'bar'; $here = <<<HERE I'm here, $foo! HERE; $now = <<<'NOW' I'm now, $foo! NOW;
$here is "I'm here, bar!", while
$now is "I'm now, $foo!".
If you don't need variable interpolation but need special characters like
$ inside your string, Nowdocs are easier to use. That's all.
