如何使用PHP将多表csv解析为html表

Question

I have a csv file which contains 2 sheets inside. I am trying to execute the csv file and convert it into a html table using php. but it is taking and displaying table of just one sheet. I am unable to find the other sheet's information.

For this I am using the following code,

 <?php
echo "<table border='1' align='center' width='70%'>

";
$f = fopen("../uploads/docs/test.csv", "r");
while (($line = fgetcsv($f)) !== false) {
        echo "<tr>";
        foreach ($line as $cell) {
                echo "<td>" . htmlspecialchars($cell) . "</td>";
        }
        echo "</tr>
";
}
fclose($f);
echo "
</table><br>";



echo "<table border='1' align='center' width='70%'>

";
$f = fopen("../uploads/docs/testing.csv", "r");
while (($line = fgetcsv($f)) !== false) {
        echo "<tr>";
        foreach ($line as $cell) {
                echo "<td>" . htmlspecialchars($cell) . "</td>";
        }
        echo "</tr>
";
}
fclose($f);
echo "
</table>";
?>

Please help me by which i can parse csv having multiple sheets in it to a html table
