How can I include "place holders" for variables in a heredoc such

Al,
Escape the $'s in your heredoc expression so that the variable names
remain and aren't evaluated, then eval() the whole expression later:
$sString = <<< hdBodyClass
<body class="\$sBodyClass">
hdBodyClass;
This sets $sString equal to:
<body class="$sBodyClass">
Then:
$sBodyClass = "contact";
eval("\$sHTML = '$sString';");
Evaluates as:
$sHTML = '<body class="contact">';
As always, be careful not to include any external data in an eval()
statement without careful sponging. Its presence in your script
should be regarded as an Achilles heel and treated with special respect.
