PHP基于自定义函数实现的汉字转拼音功能实例

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); } }?><form action="./" method="get"> <input type="text" name="cat_name" value="<?php echo $cat_name?>" /> <input type="submit" value="提交" /><br /></form><?php echo $letters;?>
