If it's a string, you can print it the same as any other string, which in 
a dom environment usually means setting up a text node and appending it 
as a child node to a relevant block element.

Sounds like you need to find a mechanism to pass the data from the php 
page to the javascript on the client machine.

Now in theory you should be able to serialise a php array into a json 
data structure, and output that json data structure in the web page in 
such a way that your javascript code on the web page has access (in it's 
javascripty way) to the same data.
