php - 如何使用php将数据数组插入mysql

Question

目前我有一个通过 print_r(); 输出时如下所示的数组；

Array
(
    [0] => Array
        (
            [R_ID] => 32
            [email] => a@a.com
            [name] => Bob
        )

    [1] => Array
        (
            [R_ID] => 32
            [email] => b@b.com
            [name] => Dan
        )

    [2] => Array
        (
            [R_ID] => 32
            [email] => c@c.com
            [name] => Paul
        )

    [3] => Array
        (
            [R_ID] => 35
            [email] => d@d.com
            [name] => Mike
        )  
)

我想将此数据插入到一个表中，每个元素值属于其各自的字段。

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 不是该表的主键*

有人可以帮助我了解我应该如何处理这种情况吗？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()); 
}
