输出json文件中文处理

<?php$json_array = array();// 1。转换为json字符串（不自动转换为unicode编码）if (version_compare(PHP_VERSION,‘5.4.0‘,‘<‘)) ???$json_string = preg_replace_callback("#\\\u([0-9a-f]{4})#i", function($matchs){return iconv(‘UCS-2BE‘,‘UTF-8‘,pack(‘H4‘, $matchs[1]));}, json_encode($json_array));else ???$json_string = json_encode($json_array, JSON_UNESCAPED_UNICODE);// 2。现在$json_string是gbk编码，转换为utf8$json_string = iconv(‘GB2312‘, ‘UTF-8‘, $tables);// 3。输出到文件file_put_contents(‘./json_string.json‘, $json_string);

json文件缩进调整

只能大概调整一下，以后再改进吧

/** * 重新调整json缩进 * @Author ??zjf * @DateTime 2017-03-10 * @param ???String ????$json json字符串 * @return ??String ????处理后的json字符串 */function reindent_json($json){ ???preg_match_all(‘/\{|\}|,/‘,$json,$matches); ???$tab = 0; ???$eol = PHP_EOL; ???foreach ($matches[0] as $key => $value) { ???????if ($value == ‘{‘) { ???????????$json = preg_replace(‘/\{(?!‘.$eol.‘)/‘, "{".$eol.str_repeat("\t", ++$tab), $json, 1); ???????}elseif ($value == ‘}‘) { ???????????$json = preg_replace(‘/([^\t])\}/‘, "$1".$eol.str_repeat("\t", --$tab)."}", $json, 1); ???????}elseif ($value == ‘,‘) { ???????????$json = preg_replace(‘/,(?!‘.$eol.‘)/‘, ",".$eol.str_repeat("\t", $tab), $json, 1); ???????} ???} ???return $json;}
