php5.4以下版本json不支持不转义内容中文的解决方法,

本文实例讲述了php5.4以下版本json不支持不转义内容中文的解决方法。分享给大家供大家参考。具体分析如下:

写ERP接口的时候遇到JAVA方接收这种json_encode后的内容

复制代码 代码如下:

{"orderCode":"1401160935542399","creator":"\u751f\u6d3b\u7528\u54c1\u6d4b\u8bd5\u5c0f\u5c4b"}


其中"creator":"\u751f\u6d3b\u7528\u54c1\u6d4b\u8bd5\u5c0f\u5c4b"为中文,目前我们用的是UTF8的。但是JAVA方接收这种的时候自动把转义后的中文转回成中文的,那签名计算方式是按这个来的,签名自然对不上了。

查了PHP手册,5.4以下的不能不转义中文,但是我们服务器上的PHP版本是5.3的,于是用PHP模拟了一个JSON方法。

复制代码 代码如下:

//模拟joson中文不转义
if (version_compare(PHP_VERSION, '5.4.0') >= 0) {
    function json_encode_ex($var) {
        return json_encode($var, JSON_UNESCAPED_UNICODE);
    }
} else {
    function json_encode_ex($var) {
        if ($var === null)
            return 'null';

        if ($var === true)
            return 'true';

        if ($var === false)
            return 'false';

        static $reps = array(
            array("\\", "/", "\n", "\t", "\r", "\b", "\f", '"', ),
            array('\\\\', '\\/', '\\n', '\\t', '\\r', '\\b', '\\f', '\"', ),
        );

        if (is_scalar($var))
            return '"' . str_replace($reps[0], $reps[1], (string) $var) . '"';

        if (!is_array($var))
            throw new Exception('JSON encoder error!');

        $isMap = false;
        $i = 0;
        foreach (array_keys($var) as $k) {
            if (!is_int($k) || $i++ != $k) {
                $isMap = true;
                break;
            }
        }

        $s = array();

        if ($isMap) {
            foreach ($var as $k => $v)
                $s[] = '"' . $k . '":' . call_user_func(__FUNCTION__, $v);

            return '{' . implode(',', $s) . '}';
        } else {
            foreach ($var as $v)
                $s[] = call_user_func(__FUNCTION__, $v);

            return '[' . implode(',', $s) . ']';
        }
    }
}

用的时候直接当内置函数用就行。json_encode_ex(array('钓鱼岛'=>'中国的'));还支持多维数组。

希望本文所述对大家的php程序设计有所帮助。
