Prefixing array keys with a string (:) in PHP

Question

Quick one; I know a solution, but I\'m looking for something more elegant if it exists.

I\'m using PDO for prepeared statements:

$sql = \"INSERT INTO         


        

Answer 1

$source->execute($sql, array(
    'foo' => $foo,
    'bar' => $bar,
    'baz' => $baz
));

This is presuming the above calls PDOStatement::execute() under the hood, with the above array as its argument.¹
