Question

interpreting php as plain text when using php function require

Answer 1

+4 A:

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

Yeah, i have done that. Even the simple require like that :<?php$content=<<<EOFecho 'hello';EOF;require '...php';?>gives me: echo 'hello'; on the siteboth files are wrapped in <?php ... ?>

@kesper: Make sure that there is no SPACE/INDENTATION before ending `EOF`. Also it would be easier if you could post your code in your question above.

Sarfraz 2010-08-01 13:16:56

that code should give echo \'hello\', you can't use functions/language constructs from within heredocs.

Answer 2

+1 A:

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"&gt;

<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.

but i would have to use echo ''; on each line ?

kasper 2010-08-01 13:26:42

@kasper do you see echo on each line here? PHP can output HTML directly http://www.php.net/manual/en/language.basic-syntax.phpmode.php

oh sorry, bad question,thanks for answer

kasper 2010-08-01 13:31:18

looks like my browser ate your code lines :)

kasper 2010-08-01 13:31:59

@kasper this is very handy feature of PHP, making php both engine and template language. Main part gather the data and then include template part, which consists of HTML and basic programming instructions.

Col. Shrapnel 2010-08-01 13:39:30

ok i'm beeing dumb or something but why call undefinied $content?

kasper 2010-08-01 13:43:17

@kasper you have to define $content somewhere of course.
