在php中将关联数组插入MySQL数据库

I have an array called $output which contains:

Array
(
    [0] => Array
        (
            [0] => J Arora
            [1] =>  India
        )

    [1] => Array
        (
            [0] => J Ramuj
            [2] =>  Russia
        )

    [2] => Array
        (
            [1] =>  KJ Tris
            [2] =>  Germany
        )

)

How can i insert these data into mysql database table like these

---------------
name   | country
-------|---------
J Arora|India
-------|--------
J Ramuj|Russia
-------|--------
KJ Tris|Germany
-------|--------

I am not able to fetch these values separately from given array as their index are not in sequence.

    Just loop it with a foreach, and use PHP native functions like current() and end() to get your elements. Given that you just have two elements in your array at all times, this should work

    foreach ($output as $v) {
    echo current($v); // Name
    echo end($v); // Country
}

    Adapt this to build your query and execute it inside the loop. Inside the loop you could do

    foreach ($output as $v) {
    $sql = "INSERT INTO table (`name`, `country`) VALUES ('".current($v)."', '".end($v)."')";
    // TODO: Execute query
}

    You should also note that any query using variables should be using prepared statements with placeholders. Both MySQLi and PDO supports this.

    Using prepared statements

    Build the query before, and execute it as you loop it with the appropriate variables bound.

    Example with PDO:

    $stmt = $pdo->prepare("INSERT INTO table (`name`, `country`) VALUES (:name, :country)");
foreach ($output as $v) {
    $stmt->execute(array("name" => current($v), "country" => end($v));
}

    Example with MySQLi:

    $stmt = $mysqli->prepare("INSERT INTO table (`name`, `country`) VALUES (?, ?)");
foreach ($output as $v) {
    $name = current($v);
    $country = end($v);
    $stmt->bind_param("ss", $name, $country);
    $stmt->execute();
}
