why can't $_GET get a string word from URL? is it array that $_GET cannot get from URL?

Hi everyone, I don't know why $_GET didn't get string from URL from another page. can you help? here my code:

First page:

<?php

require("connection.php");

error_reporting(E_ALL);

$sql = $GaryDB->prepare("SHOW TABLES");
$list = "";
$list2 = "";

$sql->execute();

while ($row = $sql->fetch()) {
    $list .= "<a href='$row[0].php?=$row[0]'>".$row[0]."</a><br />";
}
?>
<!DOCTYPE HTML>
<html lang="en">
<head>
    <title>Pinky's</title>
    <link href="paparazzi.png" rel="icon">
    <style>
        * {
            font-family: Helvetica;
            text-decoration: none;
        }
        body {
            margin-left: 300px;
            margin-top: 100px;
            margin-right: 300px;
        }
    </style>
</head>
<body>
<table>
    <tr><td>Please Select</td><td></td></tr>
    <tr><td><?php echo $list ?></td></tr>

</table>
</body>
</html>

link at left-bottom show localhost:8888/Braclets.php?=Braclet

Then why can't $_GET get this strong "Bracelets"?

<?php

require("connection.php");

        $kids = $_GET['Kids'];

        echo $kids;

        $sql = $GaryDB->prepare("SELECT * FROM $kids");

        echo $sql;

?>

Simply because there is no reference to 'kids' in the url, you have '=' and value, but no key of 'kids'

There is a reference in url already. I set up the loop in link like this:

bracelets.php?=bracelets

earrings.php?=earrings

kids.php?=kids

necklaces.php?=necklaces

rings.php?=rings

then There is file name already - bracelets.php, earrings.php, kids.php, necklaces.php, and rings.php. So, $_GET should grab reference key from those string in URL, but it didn't. I think $_GET doesn't grab when it come with array. I used implode to convert array to string, but still not work.
