如何使用PHP将数据数组插入MySQL

Question

当前，当通过print_r（）输出时，我有一个类似于以下内容的数组；

Array
(
    [0] => Array
        (
            [R_ID] => 32
            [email] => [e-mail]
            [name] => Bob
        )

    [1] => Array
        (
            [R_ID] => 32
            [email] => [e-mail]
            [name] => Dan
        )

    [2] => Array
        (
            [R_ID] => 32
            [email] => [e-mail]
            [name] => Paul
        )

    [3] => Array
        (
            [R_ID] => 35
            [email] => [e-mail]
            [name] => Mike
        )  
)

我想将此数据插入到一个表中，每个元素值都属于其各自的字段。

目前，我的php代码如下所示

if(is_array($EMailArr)){
    foreach($EMailArr as $R_ID => $email => $name){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ('$R_ID', '$email', '$name')";
    mysql_query($sql) or exit(mysql_error()); 
    }
}

注意：R_ID不是此表中的主键。

有人可以帮助我了解如何应对这种情况吗？感谢您的阅读和帮助！

问候。

我会避免对每个条目进行查询。

if(is_array($EMailArr)){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";

    $valuesArr = array();
    foreach($EMailArr as $row){

        $R_ID = (int) $row['R_ID'];
        $email = mysql_real_escape_string( $row['email'] );
        $name = mysql_real_escape_string( $row['name'] );

        $valuesArr[] = "('$R_ID', '$email', '$name')";
    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}
