如何提取下面的数组＆amp;插入3个数据＆amp; 2查询

提取此阵列＆amp;给我2排＆amp; 3栏

Array
(
    [name] => Array
        (
            [0] => AAAAA
            [1] => BBBBB
        )

    [number] => Array
        (
            [0] => 7878787878
            [1] => 9898989898
        )

    [email] => Array
        (
            [0] => a@gmail.com
            [1] => b@gmail.com
        )

)

我们需要通过foreach循环进行以下查询

INSERT INTO `contact_person` SET customer_id='131',cp_name='AAAAA',cp_phone='7878787878',cp_email='a@gmail.com

INSERT INTO `contact_person` SET customer_id='131',cp_name='BBBBB',cp_phone='9898989898',cp_email='b@gmail.com'

Answer 1

考虑像for loop一样：

$length = count($yourarray['name']);
$queries = new array();
for(i = 0; i < $length; i++) {
    $queries[] = "INSERT INTO `contact_person` SET customer_id='131',
                 cp_name='" . $yourarray['name'][i] . "',
                 cp_phone='" . $yourarray['number'][i] . "',
                 cp_email='" . $yourarray['email'][i] " . "'";
}

这将创建所有插入查询并将它们放在名为$queries

的数组中

注意：此代码假设您总是拥有相同数量的姓名，号码和电子邮件

Answer 2

$newArr = array();
foreach($arr as $key=>$val){
    foreach($val as $k=>$v){
      $newArr[$k][$key] =   $v;
    }
}
echo "<pre>"; print_r($newArr);

现在，您可以在foreach()中运行插入查询，例如：

foreach($newArr as $key=>$val){
echo "INSERT INTO `contact_person` SET customer_id='131',
                 cp_name='" . $val['name'] . "',
                 cp_phone='" . $val['number'] . "',
                 cp_email='" . $val['email'] " . "'";
echo "<br />";
}

Answer 3

您可以使用以下函数汇总数组。

function getSummary($array){
    $summary = [];
    foreach( $array as $col => $data ){
        foreach( $data as $key => $value ){
            $summary[$key][$col] = $value;
        }
    }
    return $summary;
}

一旦将汇总数组传递给下面的函数，您将获得查询。我假设您需要INSERT查询。

function makeQueries($summary){
    foreach( $summary as $data ) {
        echo $sql = "INSERT INTO `contact_person` (customer_id, cp_name, cp_phone, cp_email) VALUES (131, '{$data['name']}', '{$data['number']}', '{$data['email']}');";
        echo "<br>";
    }
}

我相信这两个功能将解决您的问题

Answer 4

使数据库中的customer_id成为自动编号，以便在插入时自动生成customer_id。

此外，所有字段都是db

中的一些文本字段

$arr = Array
(
    'name' => Array
        (
            "AAAAA", "BBBBB"
        ),

    'number' => Array
        (
             "7878787878", "9898989898"
        ),

    'email' => Array
        (
            "a@gmail.com", "b@gmail.com"
        )
);
$count = count($arr['name']);
$sql = "";
if ($count > 0) {
    $sql = "INSERT INTO `contact_person` (cp_name, cp_phone, cp_email) VALUES ";
    for ($i=0; $i < $count; $i++) { 
        $sql .= ($i+1==$count) ? "('".$arr['name'][$i]."', '".$arr['number'][$i]."', '".$arr['email'][$i]."'')" : "('".$arr['name'][$i]."', '".$arr['number'][$i]."', '".$arr['email'][$i]."''), ";
    }
}

echo ($sql);
