php do not give me an html class, how to zoom magnify a table?

good day I think I did not know how to ask my question well. the problem I have is that I want a table to show me a magnifying glass style ZOOM of my table products when passing the pointer over, and of course the data I require.

<link type="text/css" href="../css/zoomy.css" rel="stylesheet">
		<script type="text/javascript" src="../js/zoomy.js"></script>
		<script type="text/javascript" src="../js/zoomy.min.js"></script>
		
		<script defer>
	$(function(){
		$('.zoom').zoomy({
			zoomSize: 256,
			round: true,
			border:'6px solid #fff'
		});
	});

that I have it on the html page and this is in a .php where I call to print my table

$row[]= "<td><a href=".$aRow['imag1']." class='zoom'><img src=".$aRow['imag1']." width=90 heigth=90 ></a></td>";

I did html and class tests on a separate page, in a single image and there it works well. in the PHP simply do not give me the class or does it relate to the ZOOM function

WHAT CAN I DO?
