Question

基本上我有这个数组，我想改成数据库查询

Array
(
    [table] => menu
    [fields] => Array
        (
            [mid] => menu_admin
            [language] => EN
            [name] => Admin
        )

)

Array
(
    [table] => user
    [fields] => Array
        (
            [uid] => 1
            [rid] => admin
            [first_name] => Admin
            [last_name] => Admin
            [email] => contact@admin.com
            [password] => xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
            [date_register] => Zend_Db_Expr Object
                (
                    [_expression:protected] => NOW()
                )

            [last_connexion] => NULL
            [enable] => 1
        )

)

依此类推......我想这样：

INSERT INTO `menu` (`mid`, `language`, `name`) VALUES
('menu_admin', 'EN', 'Admin');
INSERT INTO `user` (`uid`, `rid`, `first_name`, `last_name`, `email`, `password`, `date_register`, `last_connexion`, `enable`) VALUES
(1, 'admin', 'Admin', 'Admin', 'contact@admin.com', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', '2014-02-27 15:33:45', '0000-00-00 00:00:00', 1);

这是我尝试的内容：

foreach ($query as $sql) { 
$keys = rtrim(explode(", ", array_keys($sql['fields']), ",")); //<--Here
$fields = rtrim(explode(", ", $sql['fields']), ",");  //<--And here
$sql = sprintf("INSERT INTO %s (%s) VALUES (%s)", $sql['table'], $fields, $keys); 
}
var_dump($sql);

以下是错误：explode() expects parameter 2 to be string, array given 但我无法理解我是如何实现它的。对此有何帮助？谢谢。

这是一个将从源数组构建SQL语句的函数：

function buildInsertSQL($array){
    foreach($array as $key => $value){
        if ($key == 'table'){
            $table = $value;    
        }
        if ($key == 'fields'){
            $columns = array_keys($value);
            $values = array_values($value);
        }
    }
    $sql = "INSERT INTO `". $table . "` (".implode(", ", $columns).")";
    $sql .= " VALUES ('".implode("', '", $values)."') ";
    return $sql;

}

$test = array(
    'table' => 'menu',
    'fields' => array(
            'mid' => 'menu_admin',
            'language' => 'EN',
            'name' => 'Admin'
        )

);

$sql = buildInsertSQL($test);
echo $sql;

Answer 2

// example code

foreach ($query as $sql)
{
    $cols = array();
    $vals = array();

    foreach($sql['fields'] as $key => $val)
    {
        array_push($cols, "`". $key."`");
        array_push($vals, "'". $val."'");
    }

    echo "INSERT INTO `".$sql['table']."` (".implode(',', $cols).") VALUES (".implode(',', $vals).")";
}

将数组更改为查询PHP
