You need JavaScript for that. PHP is just meant to send data to your web browser. — mehulmpt

Click events are carried out on the client side, for which you will need JavaScript. Ask if you have difficulties in binding click events to fetch data from JS objects. — Yogesh Mistry

You can append the content to a div and increment a counter used like id post_fix follow this simple exemple i created for you.

<?php 
echo "Associative 2-dimensional array:<br>";

$marks1=array(
    array("Maths"=>80,"Physics"=>89,"Chemistry"=>79),
    array("Maths"=>90,"Physics"=>78,"Chemistry"=>87),
    array("Maths"=>78,"Physics"=>90,"Chemistry"=>79)
);
echo "<ul>";
for($r=0;$r<count($marks1);$r++)
{
    echo "<li>";
    foreach($marks1[$r] as $key=>$value)
    {
        echo "<span id='$key$r'>".$key." = ".$value."</span>  ";
    }
    echo "</li>";
    echo "<br><br>";
}
echo "</ul>";

?>
<button onclick="show()">Show</button>
<div id="here"></div>
<script type="text/javascript">
    var i=0;
        function show()
        {

            document.getElementById("here").innerHTML = document.getElementById("Maths"+i).innerHTML;
            i++;
        }
</script>

Hope that will help you.
