sb17joker 0 Posted August 31, 2012 Report Share Posted August 31, 2012 I have seen this syntax in some scripts that I have downloaded, & it interested me, so I searched for info on it, & have come up with nothing. I have searched php.net, nothing... is this a php function? a way to end php so html can be used? I don't even know what to call it, it doesn't seem to follow any rules... ie: operator, function, variable. I have tested it out, & used it as I have seen it being used, such as: <?php $content =<<<HTML stuff in middle HTML; echo "Before ".$content." After"; This outputs "Before stuff in middle After". if someone could point me to more information on this & what rules apply, I would be grateful. Thank you Scott Quote Link to post Share on other sites

Thank you Scott ok, seems I actually have found something. It seems that this is what is called heredoc syntax, & it doesn't matter what the letters are, such as $content =<<<STUFF stuff in middle STUFF; echo $content; does the same as <<<HTML... & heredocs will parse for variables inside curly brackets such as: $word = "foo"; $content =<<<HTML stuff {$word} middle HTML; echo $content; outputs "stuff foo middle"; also learned "nowdoc"s have single quotes around the "name", do similar, but do not parse content such as: $word = "foo"; $content =<<<'HTML' stuff {$word} middle HTML; echo $content; outputs "stuff {$word} middle"; so there is what I have learned in a nutshell... if you have more info I'll still be grateful, I like to learn.
