Question

我有这个功能

protected function insert($data){
        $data['datecreated'] = date('Y-m-d h:i:s');
        echo "array_keys(data) = ".$data['datecreated'];
        var_dump($data);
        echo array_keys($data);
        $sql = "INSERT INTO {$this->table_name} (".  array_keys($data).")"; 
        $sql.= " VALUES ('";
        $sql.=implode("','", $data);
        $sql.=")";
        $this->execute($sql);
        $this->last_id = mysql_insert_id();
    }

当我读到array_keys($data)时，它返回'Array'而不是键我称之为$this->insert(array());为什么会这样？编辑：这是输出

array_keys(data) = 2012-05-18 04:44:46array(2) { [0]=> array(0) { } ["datecreated"]=> string(19) "2012-05-18 04:44:46" } Array

Answer 1

array_keys返回包含所有键的数组。你需要破坏那个

implode(',', array_keys($data));

编辑：你可能想看一下这部分

$sql.=implode("','", $data);
$sql.=")";

您需要一个起始和尾随'。

Answer 2

你想要的是implode(',', array_keys($data))，因为array_keys()返回一个包含所有键的数组 - 但你想要一个以逗号分隔的字符串：

$sql = "INSERT INTO {$this->table_name} (".implode(',', array_keys($data)).")";

顺便说一句，我希望$data中的值已经转义。如果没有，请将implode("','", $data)替换为implode("','", array_map('mysql_real_escape_string', $data))

array_keys在php中返回Array
