Parse error: syntax error, unexpected T_SL on line 23

Question

I am getting this error:

Parse error: syntax error, unexpected T_SL on line 23

Here is line 23:

$selectorder = <<<ORDER 

Here it is in context:

$grid->setUrl('myfirstgrid.php');

$selectorder = <<<ORDER 
function(rowid, selected) 
{ 
    if(rowid != null) { 
        alert("selected: "+rowid); 
    } 
} 
ORDER;
$grid->setGridEvent('onSelectRow', $selectorder);

What is causing this error?

I personally don't know what <<< does and have never used it, I got it from a tutorial. I tried to google it, but you can't google characters like that :(

Answer 1

<<< is for heredoc: See manual

Answer 2

Check for whitespace after <<<ORDER. There should be no blank characters.

Answer 3

Make sure that there is no SPACE/INDENTATION before ending ORDER;
