    inclosed variable heredoc

    hi all

    <?php
    $foo="NO";
    $text=<<<EO
    The variable is named: $foo
    EO;

    if (TRUE)
    {
    $foo="YES";
    die($text); //how to get $foo="YES" into $text?
    }
    ?>

    Trying to get $foo="YES" into $text, but NO appears instead. Any ideas?

    gr Jan

      The way you are doing it, $text has already been assigned a value before
      you're setting the new value for $foo.

      Turn it around and you will be fine:

      $foo="NO";

      if (TRUE) {
      $foo="YES";
      }

      $text=<<<EO
      The variable is named: $foo
      EO;

      print $text;

          As Janwillem said, you're doing things the wrong way around. What I think
          you're actually asking for is a way to specify the format of the error
          message at the top of the code instead of way down the bottom when the
          error actually happens. Here, sprintf() is your friend...

          <?php
          $foo = 'NO';
          define('ERRMSG_ FOO', 'Foo is now "%s", so I shall die.');

          if (1)
          {
          $foo = 'YES';
          die(sprintf(ERR MSG_FOO, $foo));
          }
          ?>

          You don't need to use a constant of course -- you could use:

          <?php
          $foo = 'NO';
          $ERRMSG_FOO = 'Foo is now "%s", so I shall die.';

          if (1)
          {
          $foo = 'YES';
          die(sprintf($ER RMSG_FOO, $foo));
          }
          ?>

          But assuming the message format is not going to change half-way through
          your script, a constant seems more sensible.

              Janwillem and Toby,

              Thanks for your quick reply

              But i dont think i made clear enough what i was aiming at (sorry about
              that): i wrote a webform (html code stored in $text), if user hits
              submit-button without filling in required formfields, form should
              reappear with warning -message added (stored in $foo)

              Any further ideas?

              gr Jan

                  HTML code stored in $text? Why not use static HTML with inline code blocks:

                  <html>
                  <body>
                  <?php if (!isset($_POST['foo'])) { ?>
                  Foo isn't set
                  <?php } ?>
                  </body>
                  </html>

                  Anyways, you can use stringified HTML and combine it with Toby's suggestion:

                  <?php

                  $html = '<html><body>%s </body></html>';
                  $err = '';

                  if (true) $error = 'You forgot to supply foo';

                  printf($html, $error);

                  ?>
