php - 如何将此数据插入mysql php

Question

Array
(
    [id] => Array
        (
            [0] => 1
            [1] => 1
            [2] => 1
        )

    [kind] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )

    [qty] => Array
        (
            [0] => 123
            [1] => 456
            [2] => 789
        )

)

这就是我的数据的样子。这是我插入 1 行的代码

function insert($table, $array_data)
{
    $key = array();
    $value = array();
    foreach($array_data as $v=>$row){
        $key[] = $v;
        $value[] = "'".$row."'";
    }
    $data_key = implode(',', $key);
    $data_value = implode(',', $value);

    $sql = "INSERT INTO ".$table."(".$data_key.") VALUES (".$data_value.")";
    $this->setQuery($sql);
    $this->query();
}

请帮我做一个函数来插入多行之类的东西

function insert_multi($table, $array_data)
{
    ...

    $sql = "INSERT INTO ".$table."(".$data_key.") VALUES (".$data_value1."), (".$data_value2.")";
    $this->setQuery($sql);
    $this->query();
}

我尝试了很多方法，但只返回空值或“Array”字符串。我的观点是让这些值(value)变成这个 INSERT INTO table (id, kind, qty) VALUES (1, v2, v3), (1, v2.1, v3.1),...
非常感谢! ^^

猜猜你想要这样的东西:

function insert_multi($table, $array_data)
{
    $sql = "INSERT INTO " . $table . " (" . implode(',', array_keys($array_data)) . ") VALUES ";
    $rows = [];
    $columns = array_keys($array_data);
    for ($ii = 0; $ii < count($array_data[$columns[0]]); $ii++) {
        $values = [];
        foreach ($columns as $column) {
            $values [] = $array_data[$column][$ii];
        }
        $rows [] = "('" . implode("','", $values) . "')";
    }
    $sql .= implode(',', $rows);

    $this->setQuery($sql);
    $this->query();
}

但是当以这种方式构建查询时，请做好 SQL 注入(inject)的准备......
