PHP中对汉字进行UNICODE编码和解码的功能
<?php //将内容进行UNICODE编码,编码后的内容格式:\u56fe\u7247 (原始:图片)function unicode_encode($name){ $name = iconv('UTF-8', 'UCS-2', $name); $len = strlen($name); $str = ''; for ($i = 0; $i < $len - 1; $i = $i + 2) { $c = $name[$i]; $c2 = $name[$i + 1]; if (ord($c) > 0) { // 两个字节的文字 $str .= '\u'.base_convert(ord($c), 10, 16).base_convert(ord($c2), 10, 16); } else { $str .= $c2; } } return $str;}// 将UNICODE编码后的内容进行解码,编码后的内容格式:\u56fe\u7247 (原始:图片)function unicode_decode($name){ // 转换编码,将Unicode编码转换成可以浏览的utf-8编码 $pattern = '/([\w]+)|(\\\u([\w]{4}))/i'; preg_match_all($pattern, $name, $matches); if (!empty($matches)) { $name = ''; for ($j = 0; $j '.unicode_encode($name).'';//解码echo '<h3>'.unicode_decode('\u56fe\u7247').'</h3>';
