mysql - PHP使用PDO库查询数据库除了NULL所有字段都返回的是字符串

Jun 06, 2016 pm 08:28 PM
mysql pdo php

返回的数组值都是字符串

[
    "id" => "4231",
    "status" => "2"
]
Copy after login
Copy after login

这个问题让我很困惑,因为这样的数据转换成json后全部都变成了字符串,虽然理论上说,数据全字符串是比较安全的,但是对接强类型语言的时候会很难搞。

设置一下PDO的属性

<code>$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);</code>
Copy after login

就可以了

无解。除非自己强制类型。输出的时候自己格式化。

function format($arr) {
    $arr['id'] = (int)$arr['id'];
    $arr['status'] = (int)$arr['status'];
    return json_encode($arr);
}
echo format(['id'=>'111','status'=>'2']);
Copy after login
