循环通过csv文件使用php mysqli预处理语句将数据插入MySQL

Question

好的，我将从我的代码开始：

include('connect.php');

// Prepared statement, prepare
if (!($stmt = $mysqli->prepare("INSERT INTO funddata(ticker, priceDate, price) VALUES (?, ?, ?)"))) {
    echo "Prepare failed: (" . $mysqli->errno . ") " . $mysqli->error;
}

//Bind the parameters to the query
$csvData = array("","",""); //Initialise the $csvData array
$priceDate = date($csvData[1]);
$stmt -> bind_param("ssd", $csvData[0], $priceDate, $csvData[2]);

$file_handle = fopen($csvfile, "r");

while (!feof($file_handle) ) {

        $csvData = fgetcsv($file_handle, 1024);
        $priceDate = date($csvData[1]);

        echo $csvData[0] . "; " . $priceDate . "; ". $csvData[2] . "<br/>";

        //Run the insert statement
        $stmt->execute();

}

fclose($file_handle);

这无法将数据插入到数据库表中，尽管它确实会导致插入大量空白行。

正在读取csv数据，正如循环内echo所证明的那样。 我在哪里错了？
