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;

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)) {

}
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
