Simple question

[448191]

I've got a simple question (Yes, I do those too  :P).

What was that thing again, whatsjemecallit, you use so you can use both single and double qoutes without having to escape them?

Something like EO>>? A link explaining what it is would be nice also.

Wait a second? <<<EOF : "End Of File"?

How the *** does that work?

I clearly missed something basic here..  :-[

example ok

[code]
echo <<<EOF
      <div id="main">
      {$j_main}
      </div><!--/main-->
    </div><!--/outer-->
  </body>
</html>
EOF;
[/code]

Nevermind, I found it.

[url=http://nl2.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc]heredoc syntax[/url]

does that mean according to that we can use anyold name like

<<<hithere

hithere;

I think it does:

[quote=php.net]Another way to delimit strings is by using heredoc syntax ("<<<"). [b]One should provide an identifier[/b] after <<<, then the string, and then the same identifier to close the quotation.

The closing identifier must begin in the first column of the line. [b]Also, the identifier used must follow the same naming rules as any other label in PHP: it must contain only alphanumeric characters and underscores, and must start with a non-digit character or underscore. [/b][/quote]

can you give an example know why use it?

what to use it on?

so on please cheers.

[redarrow]

it's a short cut not to use the double quotes then?

[code]
<?php
$test=<<<eof
my name is redarrow
eof;
echo $test;
?>
[/code]

Sort of. It behaves identically to double quotes(ie expands variables), but you don't actually use double double quotes, so you can include double quotes in the string without having to escape them.

To bad there isn't an equivalent that mimics single quotes, since that's what I'd prefer. (or is there?  ::))
