PHP error when attempting to print variables within an echo using heredoc

Question

When I try to do this:

var $example = "Example";
echo <<<EOT
<p>$example</p>
EOT;

I get this error:

Parse error: syntax error, unexpected T_VAR in ..... on line ...

What is going on here?? To my knowledge this should work.

I'm using PHP 5.3.5.

O_o "var"... this brings up old memories to my head. Why are you using this keyword? Why not just remove it? — greg0ire

The var keyword on the first line is for declaring variables in classes only. Leave it out.

And even there it's just an old leftover from PHP 4.

There is no keyword var in PHP. Not in PHP5 anyway - it's only accepted due to backward compatibility, and is used to define class variables.

D'oh. Removing the 'var' keyword fixed it. Thanks for the input guys!

Unfortunately however it didn't solve my actual problem. See here:

$param = array_merge($_REQUEST, $_FILES, $_COOKIE);

$param['example'] = "example";

example();

function example()
{
    global $param;
    echo <<<EOT
        <p>$param['example']</p>
EOT;
    return;
}

This time the complaint is:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in ..... on line ...

Again, what is going on here?

Drop the quotes. i.e. write $param[example]. Or write {$param['example']}.

try surrounding the argument with curly braces: {$param['example']}

Thank you as well. I actually prefer that way.
