I have main site to which i put code using require function, but when i add php functions into it, they appear as plain text. The php code is rather long so i won't paste it here. Could anyone help me with that?

Thanks

ok i am adding some code:

require part with onl开发者_开发技巧y one function:

<?php
$content=<<<EOF
echo 'hello';
EOF;
require 'whatever.php';
?>

and main part:

<?php
echo <<<CONT
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>
    <head>
        ...
    </head>
    <body id="body">
        <div id="container">
        $content
        </div>
        <div id="add_func">
        </div>
    </body>
</html>
CONT;
?>

Make sure that You wrap your code in <?php.....?> tags.

Update:

No need to use the heredoc syntax for what you are doing, you could modify you code like this:

<?php
  echo 'hello';
  require 'whatever.php';
?>

And:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        ...
    </head>
    <body id="body">
        <div id="container">
        <?php echo $content; ?>
        </div>
        <div id="add_func">
        </div>
    </body>
</html>

just get rid of heredoc

require part

<?php
echo 'hello';
require 'whatever.php';
?>

main part

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>
    <head>
        ...
    </head>
    <body id="body">
        <div id="container">
        <?php echo $content ?>
        </div>
        <div id="add_func">
        </div>
    </body>
</html>

that's all
PHP is not Perl, heredoc is useless here, even if properly used. Just never use this ugly syntax.
