Unicode编码我们用到的不多因为Unicode编码在源码中都是字符了,但有时会用到Unicode编码了,下面我们一起来看一篇PHP Unicode编码相互转换的例子,希望例子能够对各位有帮助.
- /**
- * $str 原始中文字符串
- * $encoding 原始字符串的编码,默认utf-8
- * $prefix 编码后的前缀,默认"&#"
- * $postfix 编码后的后缀,默认";"
- */
- function unicode_encode($str, $encoding = 'utf-8', $prefix = '&#', $postfix = ';') {
- //将字符串拆分
- $str = <a href="/tags.php/iconv/" target="_blank">iconv</a>("UTF-8", "gb2312", $str);
- $cind = 0;
- $arr_cont = array();
- for ($i = 0; $i < strlen($str); $i++) {
- if (strlen(<a href="/tags.php/substr/" target="_blank">substr</a>($str, $cind, 1)) > 0) {
- if (ord(substr($str, $cind, 1)) < 0xA1) { //如果为英文则取1个字节
- array_push($arr_cont, substr($str, $cind, 1));
- $cind++;
- } else {
- array_push($arr_cont, substr($str, $cind, 2));
- $cind+=2;
- }
- }
- }
- <a href="/tags.php/foreach/" target="_blank">foreach</a> ($arr_cont as &$row) {
- $row = iconv("gb2312", "UTF-8", $row);
- }
- //转换Unicode码
- foreach ($arr_cont as $key => $value) {
- $unicodestr.= $prefix . base_convert(bin2hex(iconv('utf-8', 'UCS-4', $value)), 16, 10) .$postfix;
- }
- return $unicodestr;
- }
- /**
- * $str Unicode编码后的字符串
- * $decoding 原始字符串的编码,默认utf-8
- * $prefix 编码字符串的前缀,默认"&#"
- * $postfix 编码字符串的后缀,默认";"
- */
- function unicode_decode($unistr, $encoding = 'utf-8', $prefix = '&#', $postfix = ';') {
- $arruni = <a href="/tags.php/explode/" target="_blank">explode</a>($prefix, $unistr);
- $unistr = '';
- for ($i = 1, $len = count($arruni); $i < $len; $i++) {
- if (strlen($postfix) > 0) {
- $arruni[$i] = substr($arruni[$i], 0, strlen($arruni[$i]) - strlen($postfix));
- }
- $temp = intval($arruni[$i]);
- $unistr .= ($temp < 256) ? chr(0) . chr($temp) : chr($temp / 256) . chr($temp % 256);
- }
- return iconv('UCS-2', $encoding, $unistr);
- }
- $str = "PHP二次开发:www.phpfensi.com";
- $unistr = unicode_encode($str);
- $unistr2 = unicode_decode($unistr);
- echo $unistr . '<br />';
- echo $unistr2 . '<br />';
- $unistr = unicode_encode($str,'GBK','\\u');
- $unistr2 = unicode_decode($unistr,'GBK','\\u');
- echo $unistr . '<br />';
- echo $unistr2 . '<br />';
