PHP -试图通过for循环插入数据到数据库中，但只有一行被填充

我正在尝试使用for循环将数据插入数据库。下面是我的代码:

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "objednavky";
// ******************************************************
include 'simple_html_dom.php';
$html = file_get_html('http://www.quickbistro.cz/cs/rozvoz');
$count = substr_count($html, '<li class="item">');
$jidloA = array();
$cenaA = array();
// ********************************************************
$conn = mysqli_connect($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    $message = "Connection failed: " . $conn->connect_error;
} else {
    for ($x = 0; $x <= $count; $x++) {
        $cenaA[$x] = $html->find("span[class=price]", $x);
        $jidloA[$x] = $html->find("div[class=article]", $x);
        $jidloSQL = strip_tags($jidloA[$x]);
        $cenaSQL = strip_tags($cenaA[$x]);
        $id = $x + 1;
        $array = array(
            "id" => $id,
            "popis" => "$jidloSQL",
            "cena" => "$cenaSQL"
        );
        $sql = "INSERT INTO jidla";
        $sql.= " (`" . implode("`, `", array_keys($array)) . "`)";
        $sql.= " VALUES ('" . implode("', '", $array) . "') ";
    }
}
if ($conn->query($sql) === TRUE) {
    echo "Data inserted succesfully";
}
else {
    echo "error creating table" . $conn->error;
}
$conn->close();
?>

当我运行脚本时，它填充表只有一行，其中只有ID填充了数字81(我试图提取的项目数)。当我试图插入一行没有循环，它是正确的，行插入项目正确，所以我猜问题是在我的循环的某个地方。
