[thelist] single quotes and arrays

[Nadeem Hosenbokus]

I gave heredoc a whirl once and couldn't get used to it. Or rather the
advantages of it didn't seem apparent.

Then I ran into problems with spacing and indents on plain text email bodies
and text file outputs and found that heredoc is brilliant for that too.

Thanks,

Hi,

To avoid escaping quotes, new lines, and frequent string concatenation, I
prefer the heredoc syntax to delimit strings of HTML. (if I can't be
bothered to externalise my HTML from my code, of course).

Reference:
http://php.net/manual/en/language.types.string.php#language.types.string.syn
tax.heredoc

Example:

    $optionHtml .= <<< EOT
<option value="$returnValue" $selected>$optionLabel</option> EOT;

Although, I did get tired of using EOT as the identifier, I just use an
underscore. hehe!
