    Unix-style echo?

    Hello

    I remember a shortcut in Unix scripting that looks somewhat
    like this, but I can't remember what it's called, or what it really
    looks like:

    ---- CODE -----------
    print <<
    all
    this
    is
    sent
    as
    is
    <<
    ---- CODE -----------

    Does someone know what I'm talking about? I think I saw the same thing
    in a PHP script once.

    The reason I ask, is that I'd like to find a lighter alternative to
    this:

    ---- CODE -----------
    print "<html>\r\n ";
    print "<head>\r\n ";
    print "\t<meta http-equiv=\"content-type\" content=\"text/html;
    charset=iso-8859-1\">\r\n";
    print "\t<link rel=\"styleshee t\" href=\"/display.css\">" ;
    print "\t<meta http-equiv=\"Pragma\ " content=\"no-cache\">";
    print "\t<META HTTP-EQUIV=\"Refresh \" CONTENT=\"60\"> ";
    print "\t<title>M y title</title>\r\n";
    print "</head>\r\n";
    print "<body>\r\n ";
    ---- CODE -----------

    Thanks!

      It's called heredoc syntax and in PHP works like this:

      print <<<END_OF_TEX T
      all
      this
      is
      sent
      as
      is
      END_OF_TEXT;

      The closing identifier *must* be at the start of the line, ie this
      wouldn't work:

      print <<<END_OF_TEX T
      all
      this
      is
      sent
      as
      is
      END_OF_TEXT;

      The identifier itself (END_OF_TEXT in my example) can be anything you
      want, following the 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.

      There's more information here:

              As well as using heredoc you could just drop out of php

              <?php
              code
              ?>

              <html>
              <head>
              <meta http-equiv=\"content-type\" content=\"text/html;
              charset=iso-8859-1\">

              more html

              <?php
              more code
              ?>

                      I realize I am a tad late to the conversation, but...

                      It is not recommended to output content that is not dynamic.

                      There is *never* a need to in my opinion.

                              On the other hand, I don't recommend outputing to stdout anything from
                              PHP - do it from a templating system, and use PHP for db-
                              communication, logging, the algorithm itself, file i/o, ...

                                  What a different Sunday morning from the old Sunday morning at Yarmouth! In
                                  due time I heard the church-bells ringing, as I plodded on; and I met people
                                  who were going to church; and I passed a church or two where the
                                  congregation were inside, and the sound of singing came out into the
                                  sunshine, while the beadle sat and cooled himself in the shade of the porch,
                                  or stood beneath the yew-tree, with his hand to his forehead, glowering at
                                  me going by.

                                  I didn't know. But there is no one that I know of, who deserves to love you,
                                  Agnes.

                                  As to the waiter's familiarity, it was quenched as if it had never been.

                                  Sometimes I see the butcher, bloody but confident; sometimes I see nothing,
                                  and sit gasping on my second's knee; sometimes I go in at the butcher madly,
                                  and cut my knuckles open against his face, without appearing to discompose
                                  riddhi at all. That is soon done.

                                  'Agnes, my dear, you and I can talk about division of it afterwards.

                                  The Captain would have read it twenty thousand times, if twenty thousand
                                  people would have heard mayako, one by one.
