PHP基于自定义函数实现的汉字转拼音功能实例
这篇文章主要介绍了PHP基于自定义函数实现的汉字转拼音功能,涉及php表单及字符串编码转换、遍历等相关操作技巧,需要的朋友可以参考下。
本文实例讲述了PHP基于自定义函数实现的汉字转拼音功能，分享给大家供大家参考，具体如下：
整个过程用到了pinyin.table文件。
pinyin.php
- <?php
- header("Content-Type:text/html;charset=utf-8");
- $letters = "";
- if ($_GET) {
- $cat_name = $_GET["cat_name"];
- $catname = convert($cat_name);
- $letters = get_letter($catname, false);
- }
- function get_letter($catname, $letter = true) {
- return $letter ? strtolower(substr(gb2py($catname), 0, 1)) : str_replace(' ', '', gb2py($catname));
- }
- function gb2py($text, $exp = '') {
- if(!$text) return '';
- $data = array();
- $tmp = @file('pinyin.table'); // 将文件作为一个数组返回。数组中的每个单元都是文件中相应的一行，包括换行符在内。
- if(!$tmp) return '';
- $tmps = count($tmp);
- for($i = 0; $i < $tmps; $i++) {
- $tmp1 = explode(" ", $tmp[$i]);
- $data[$i]=array($tmp1[0], $tmp1[1]);
- }
- $r = array();
- $k = 0;
- $textlen = strlen($text);
- for($i = 0; $i < $textlen; $i++) {
- $p = ord(substr($text, $i, 1));
- if($p > 160) {
- $q = ord(substr($text, ++$i, 1));
- $p = $p*256+$q-65536;
- }
- if($p > 0 && $p < 160) {
- $r[$k] = chr($p);
- } elseif($p< -20319 || $p > -10247) {
- $r[$k] = '';
- } else {
- for($j = $tmps-1; $j >= 0; $j--) {
- if($data[$j][1]<=$p) break;
- }
- $r[$k] = $data[$j][0];
- }
- $k++;
- }
- return implode($exp, $r);
- }
- function convert($str, $from = 'utf-8', $to = 'gb2312') {
- if(!$str) return '';
- $from = strtolower($from);
- $to = strtolower($to);
- if($from == $to) return $str;
- $from = str_replace('gbk', 'gb2312', $from);
- $to = str_replace('gbk', 'gb2312', $to);
- $from = str_replace('utf8', 'utf-8', $from);
- $to = str_replace('utf8', 'utf-8', $to);
- if($from == $to) return $str;
- $tmp = array();
- if(function_exists('iconv')) {
- if(is_array($str)) {
- foreach($str as $key => $val) {
- $tmp[$key] = iconv($from, $to."//IGNORE", $val);
- }
- return $tmp;
- } else {
- return iconv($from, $to."//IGNORE", $str);
- }
- } else if(function_exists('mb_convert_encoding')) {
- if(is_array($str)) {
- foreach($str as $key => $val) {
- $tmp[$key] = mb_convert_encoding($val, $to, $from);
- }
- return $tmp;
- } else {
- return mb_convert_encoding($str, $to, $from);
- }
- } else {
- require_once 'convert.func.php';
- return dconvert($str, $to, $from);
- }
- }
- ?>
