输入数组的每个元素作为每个mysql列的记录

Question

我想要的是在我的数据库的一个字段中输入数组的每个元素这是我的结构示例表记录有四个字段 value1、value2 value3、value4 我想输入从以下代码生成的以下记录

arraynew = array("5878-1","8978-12","2523-1");
$dato1 = "00320555555";
$dato2 = "22/02/2018";
$dato3 = "Maria Mercedes del Barrio";
$dato4 = $arraynew;

$data = array($dato1,$dato2,$dato3,$dato4);

$nuevo = array();
for($i= 0; $i < count($dato4); $i++ ){
    array_push($nuevo, array(
        $data[0],
        $data[1],
        $data[2],
        $data[3][$i]
    ));
}
echo print_r($nuevo);
echo var_dump($nuevo);

这是数组的结构

Array ( [0] => Array ( [0] => 00320555555 [1] => 22/02/2018 [2] => Maria Mercedes del Barrio [3] => 5878-1 ) [1] => Array ( [0] => 00320555555 [1] => 22/02/2018 [2] => Maria Mercedes del Barrio [3] => 8978-12 ) [2] => Array ( [0] => 00320555555 [1] => 22/02/2018 [2] => Maria Mercedes del Barrio [3] => 2523-1 ) ) 1
array (size=3)
  0 => 
    array (size=4)
      0 => string '00320555555' (length=11)
      1 => string '22/02/2018' (length=10)
      2 => string 'Maria Mercedes del Barrio' (length=25)
      3 => string '5878-1' (length=6)
  1 => 
    array (size=4)
      0 => string '00320555555' (length=11)
      1 => string '22/02/2018' (length=10)
      2 => string 'Maria Mercedes del Barrio' (length=25)
      3 => string '8978-12' (length=7)
  2 => 
    array (size=4)
      0 => string '00320555555' (length=11)
      1 => string '22/02/2018' (length=10)
      2 => string 'Maria Mercedes del Barrio' (length=25)
      3 => string '2523-1' (length=6)

我需要输入每个数组，将其与相应的字段一起输入一行

我假设您正在处理用户提供的数据，因此需要一个 mysqli 准备好的语句。我的方法将对数据库进行 3 次调用，并记录查询产生的受影响行数。

（我已经在我的服务器上测试过这段代码是成功的。）

代码：

$mysqli = new mysqli(...$fourIndexedCredentials);
$stmt = $mysqli->prepare("INSERT INTO tablename (value1, value2, value3, value4) VALUES (?,?,?,?)");
$stmt->bind_param("ssss", $dato1, $dato2, $dato3, $dato4);

$dato1 = "00320555555";
$dato2 = "22/02/2018";
$dato3 = "Maria Mercedes del Barrio";
$arraynew = ["5878-1", "8978-12", "2523-1"];
$tally = 0;
foreach ($arraynew as $dato4) {  // the declaration of $dato4 is all that is required for binding
    if ($stmt->execute()) {
        ++$tally;
    }
}
echo $tally;  // output: 3
