php使用json_encode中有"

如果你在 PHP 中使用 `json_encode` 函数将数据转换为 JSON 字符串时，如果原始数据中包含双引号字符 `"`, 那么输出的 JSON 字符串中会自动将双引号字符进行转义，即使用 `\"` 表示双引号字符。

例如，如果原始数据是一个包含双引号的字符串 `"Hello \"world\""`, 使用 `json_encode` 函数将其转换为 JSON 字符串时，输出的字符串将是`"Hello \"world\""`。这样，其他使用该 JSON 字符串的程序或库在解析 JSON 时就不会出错。

php json_encode 去除转义的&quot

如果你想要在 PHP 中使用 `json_encode` 函数时去除转义的 `"`，可以使用 `JSON_UNESCAPED_SLASHES` 和 `JSON_UNESCAPED_UNICODE` 参数来实现。具体方法如下：

// 定义一个包含 " 的数组
$arr = array('name' => 'John', 'message' => 'Hello "world"');

// 使用 json_encode 函数将数组转换为 JSON 格式的字符串，去除转义的 "
$json_str = json_encode($arr, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
echo $json_str;

输出结果如下：

{"name":"John","message":"Hello \"world\""}

可以看到，字符串中的 `"` 已经被转换成了双引号 `"`, 并且没有被转义。

这是一个包含多个键值对的 JSON 对象。其中包括合同的一些基本信息，如名称、项目 ID、签订日期、到期日期、合同金额、收费方式、盖章人、盖章类型、盖章数量、文件路径和备注等。其中一些键的值是 JSON 数组，需要进一步解析。

以下是将该 JSON 对象转换成字符串的 PHP 代码：

$json = '{"name":"12312","project_id":"87156","project_name":"上上下下左左右右baba与聚法科技（长春）有限公司与公司、证券、保险、票据等有关的民事纠纷","client":"[{"type":"自然人","customer_id":"80236","customer_name":"上上下下左左右右baba"}]","sign_date":"2023-06-06","expire_date":"2023-06-21","subject_amount":"123","contract_amount":"123","charge_method":"一次性,分阶段,风险,计时","equity_amount":"13811","amount_info":"[{"type":"一次性","pay_date":"2023-07-03","charge_amount":"12"},{"type":"分阶段","pay_date":"2023-06-13","charge_amount":"123","is_satisfy":"是","pay_condition":"12312"},{"type":"风险","pay_date":"","charge_amount":"","is_satisfy":"是","pay_condition":"123","basic_amount":"123","risk_amount":"12","object_amount":"123123","object":"赔偿金","risk_prop":"13213","member":"","rate":"","hours":""},{"type":"计时","member_id":"392159","member":"曹野","rate":"11","hours":"1231"}]","seal_person":"123","seal_type":"律所公章,法人名章,财务章","seal_num":"123","file_path":"[{"title":"导入错误数据 (15).xls","path":"382585/1686381522542/导入错误数据 (15).xls","size":"91136"},{"title":"3.txt","path":"382585/1686561731102/3.txt","size":44078}]","remark":"123123"}';

$data = json_decode(str_replace('"', '"', $json), true);
$str = '';

foreach ($data as $key => $value) {
    if (is_array($value)) {
        $value = json_encode($value);
    }
    $str .= $key . ':' . $value . ',';
}

$str = '{' . rtrim($str, ',') . '}';

echo $str;
