Can't get multiline with heredoc

MacForMore · #1 04-Oct-2009, 07:33

I'm working some samples, learning PHP, and I can't get the heredoc construct to output multiline text in the browser.

My samples come from an O'Reilly book and various websites.

Am I doing something wrong?

I'm a mac newbie doing this in Netbeans on the mac with MAMP 1.8.2 installed. Mamp has PHP 5 with Zend Extensions (don't know what that is). I copied the text for index.php to another editor, thinking it might be something with netbeans, but that didn't help.

this code, below, outputs only one line.

PHP Code:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
    </head>
    <body>
        <?php
        $variables = "a test variable";
$string = <<< END_OF_STRING
            this is a multi-line
            string containing variables
            and single quotes '
            and double quotes "
            and slashes \
            do not need to be escaped
END_OF_STRING;
        echo $string
        ?>
    </body>
</html>

the output in the browser looks like this

Quote:

this is a multi-line string containing a test variable and single quotes ' and double quotes " and slashes \ do not need to be escaped

You created a string and the browser displayed the string.

If you want to force parts of the multi-line string to appear on separate lines, you put a "break" tag wherever you need it.

For example

PHP Code:


<?php
$string = <<< END_OF_STRING
            This is a multi-line
            string containing several goodies. <br /><br />
            Single quotes ' <br />
            and double quotes " <br />
            and slashes \ <br />
            do not need to be escaped!
END_OF_STRING;
        echo $string;
?>

Browser should show something like the following:

Code:

This is a multi-line string containing several goodies.

Single quotes '
and double quotes "
and slashes \
do not need to be escaped!

Regards,

Dave
