Question

It is spitting the synatx error with this part of cdoe.can you please tell me what is wrong with this code

class House{
    private $color;

    public function paint($color){
        $ret_col = create_function("\$color", "Painting with the color \$color");
        return $ret_col;    
    } 
}

$hs = new House();
$col = $hs->paint('red');
echo $col;

Parse error: syntax error, unexpected T_STRING in test.php(37) runtime-created function on line 1

Answer 1

Your Function body is not valid Php code.

Maybe you should write it

class House{
    private $color;

    public function paint($color){
        $ret_col = create_function("\$color", "return \"Painting with the color \$color\";");
        return $ret_col;    
    } 
}

$hs = new House();
$col = $hs->paint('red');
echo $col();

Edit: Fixed the col error Rocket pointed out.

And also the closure example Kendal Hopkins has is actually an nicer way for php 5.3+.
