php中不转义中文字符的 json 编码方法
虽说最新的 PHP 5.4 已经良好支持 JSON 中文编码,即通过 JSON_UNESCAPED_UNICODE 参数,例如:
json_encode("中文", JSON_UNESCAPED_UNICODE)对于早前 PHP 版本,处理不转义中文字符的 json 编码
PHP 和 JavaScript 交互其实很方便,PHP 原生也提供了对 JSON 格式的支持。主要包括 JSON 编码和解码两个函数:
json_endoce: http://cn.php.net/json_encode
json_dedoce: http://cn.php.net/json_decodejson_encode
对变量进行 JSON 编码,并返回 value 值的 JSON 形式,例如如下:
<?php array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5); echo json_encode($arr); ?>
以上代码执行后输出:{"a":1,"b":2,"c":3,"d":4,"e":5}
假如要编码的数据源(一般是一个数组),value 中包含中文,经过 json_encode 处理后输出的是 unicode 编码,代码如下:
<?php $arr = array( 'a' => '芒果小站' ); echo json_encode($arr); ?>
以上代码执行后输出,代码如下:
{"a":"u8292u679Cu5C0Fu7AD9"}
PHP 底层已经做了 unicode 处理,如果嫌它不够直观,可以利用 urlencode 和urldecode,方法绕过这个转码为 unicode 的过程,代码如下:
$arr = array ('a'=>urlencode('芒果小站'));
echo urldecode(json_encode($arr));以上代码执行后输出:{"a":"芒果小站"}
这里分享个更完美的方法:
<?php /** * 不转义中文字符的 json 编码方法 * @param array $arr 待编码数组 * @return string */ function encode($arr) { $str = json_encode($arr); $search = "#u([0-9a-f]+)#ie"; $replace = "iconv('UCS-2', 'UTF-8', pack('H4', '1'))"; return preg_replace($search, $replace, $str); } ?>
