php 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,之前写过 PHP 输出中文 JSON 字符串这篇文章,这里分享个更完美的方法:
/**
* 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);
}
