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);

}

}

?>

<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;

?>
