When a string is between 'single quotes', variables are not parsed.
This means that after
$query = 'SELECT $w'
The variable query literaly contains SELECT $w. To use the value of the
variable w instead, use double quotes:
$query = "SELECT $w"
This becomes SELECT and then the value of variable w.

Another option is to use the concatination operator, which is a dot.
$query = 'SELECT '.$w
This way, the string 'SELECT ' and the variable w are concatenated
together.
