php字符串编码相互转换函数(GBK/UTF-8)
虽然说php自带了编码转换函数,但是在使用时会碰到字符丢失问题了,为了解决这个问题小编整理了两上将非GBK字符集的编码转为GBK与将非UTF-8字符集的编码转为UTF-8的函数,希望能帮助到各位.
例子代码如下:
- <?php
- /**
- * 将非GBK字符集的编码转为GBK
- *
- * @param mixed $mixed 源数据
- *
- * @return mixed GBK格式数据
- */
- function charsetToGBK($mixed)
- {
- if (is_array($mixed)) {
- foreach ($mixed as $k => $v) {
- if (is_array($v)) {
- $mixed[$k] = charsetToGBK($v);
- } else {
- $encode = mb_detect_encoding()($v, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
- if ($encode == 'UTF-8') {
- $mixed[$k] = iconv('UTF-8', 'GBK', $v);
- }
- }
- }
- } else {
- $encode = mb_detect_encoding($mixed, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
- //var_dump($encode);
- if ($encode == 'UTF-8') {
- $mixed = iconv('UTF-8', 'GBK', $mixed);
- }
- }
- return $mixed;
- }
- /**
- * 将非UTF-8字符集的编码转为UTF-8
- *
- * @param mixed $mixed 源数据
- *
- * @return mixed utf-8格式数据
- */
- function charsetToUTF8($mixed)
- {
- if (is_array($mixed)) {
- foreach ($mixed as $k => $v) {
- if (is_array($v)) {
- $mixed[$k] = charsetToUTF8($v);
- } else { //开源软件:phpfensi.com
- $encode = mb_detect_encoding($v, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
- if ($encode == 'EUC-CN') {
- $mixed[$k] = iconv('GBK', 'UTF-8', $v);
- }
- }
- }
- } else {
- $encode = mb_detect_encoding($mixed, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
- if ($encode == 'EUC-CN') {
- $mixed = iconv('GBK', 'UTF-8', $mixed);
- }
- }
- return $mixed;
- }
- ?>
