php字符串对应替换（把一些拼音换成对应的汉字）

PHP str_ireplace() 函数使用一个字符串替换字符串中的另一些字符。

<php

$find = "anyang";

$replace = "安阳";

$arr = "anyang测试anyang";

$newstr = str_ireplace($find,$replace,$arr);

echo $newstr;

>

使用这个str_ireplace()就能替换了，而且还不用担心大小写问题，如果不用考虑大小写那就使用str_replace()即可！

参数如下：

str_ireplace(find,replace,string,count)

参数 描述

find 必需。规定要查找的值。

replace 必需。规定替换 find 中的值的值。

string 必需。规定被搜索的字符串。

count 可选。一个变量，对替换数进行计数。

欢迎采纳！

使用explode就可以，例如：

<php

$s='阿a,啊a,茬cha,茶cha,嵖cha';

foreach(explode(',',$s) as $code){

$ch=substr($code,0,2);

$code=substr($code,2);

echo "$ch\t$code<br>\n";

}

>

问题很抽象，没有具体补充吗？在电脑上你可以转换一下输入法，过去常用的拼音输入智能abc，现在常用的搜狗输入法，都可以将拼音转换成汉字，只要你输入相应的拼音，然后按数字选择你要打的字就可以了。若是手机的话，因手机而异，不好细说，但是都不会很难，可以找亲近的人研究一下

前些天，我也要用生成拼音的，找了很多，发现没有完全正确的，因为转换要用到一个函数进行转换字符集。好像GB2312字符集的都可以正确生成拼音，GBK字符集的就很多错误了。可能是因为字符集内并非按拼音的吧。

如果不想提交表单的话，那只能用ajax去实时提交字符串到后端php，将翻译后的内容返回前端，并在ajax回调函数中将译文填到第二个input里。

ajax的用法请自行查资料。

至于拼音转换，这需要一个拼音库，我这有一个，是从dede里提取出来的，也许可以帮到你。

//示例

echo GetPinyin("魍魉");

/

  汉字转拼音

  @param string $str 待转换的字符串

  @param string $charset 字符串编码

  @param bool $ishead 是否只提取首字母

  @return string 返回结果

 /

function GetPinyin($str,$charset="utf-8",$ishead = 0) {

    $restr = '';

    $str = trim($str);

    if($charset=="utf-8"){

        $str=iconv("utf-8","gb2312",$str);

    }

    $slen = strlen($str);

    $pinyins=array();

    if ($slen < 2) {

        return $str;

    }

    $fp = fopen('pinyindat', 'r');

    while (!feof($fp)) {

        $line = trim(fgets($fp));

        $pinyins[$line[0] $line[1]] = substr($line, 3, strlen($line) - 3);

    }

    fclose($fp);

    for ($i = 0; $i < $slen; $i++) {

        if (ord($str[$i]) > 0x80) {

            $c = $str[$i] $str[$i + 1];

            $i++;

            if (isset($pinyins[$c])) {

                if ($ishead == 0) {

                    $restr = $pinyins[$c];

                } else {

                    $restr = $pinyins[$c][0];

                }

            } else {

                $restr = "_";

            }

        } else if (preg_match("/[a-z0-9]/i", $str[$i])) {

            $restr = $str[$i];

        } else {

            $restr = "_";

        }

    }

    return $restr;

}
