To get this to work I had to assign the variable to another variable & then echo the new variable;
$var = array(
'name' => array(
'first' => "Bob",
'last' => "Loblaw"
)
);
//the new variable is called "$fname"
$fname=$var[name][first];
//then I echo $fname, otherwis the whole thisng fails.
echo "My first name is $fname!<br>";
