php汉字转数字的方法：首先创建一个PHP示例文件；然后通过自定义的“checkNatInt”方法实现转换；最后通过echo输出转换结果即可。

php实现中文转数字(测试好用)

分享一个辅助函数，使用php尽可能识别出字符串中的数字，

先上代码

function checkNatInt($str) {
 $map = array(
 '一' => '1','二' => '2','三' => '3','四' => '4','五' => '5','六' => '6','七' => '7','八' => '8','九' => '9',
 '壹' => '1','贰' => '2','叁' => '3','肆' => '4','伍' => '5','陆' => '6','柒' => '7','捌' => '8','玖' => '9',
 '零' => '0','两' => '2',
 '仟' => '千','佰' => '百','拾' => '十',
 '万万' => '亿',
 ); 
 
 $str = str_replace(array_keys($map), array_values($map), $str);
 $str = checkString($str, '/([d亿万千百十]+)/u');
 
 $func_c2i = function ($str, $plus = false) use(&$func_c2i) {
 if(false === $plus) {
 $plus = array('亿' => 100000000,'万' => 10000,'千' => 1000,'百' => 100,'十' => 10,);
 } 
 
 $i = 0;
 if($plus)
 foreach($plus as $k => $v) {
 $i++;
 if(strpos($str, $k) !== false) {
 $ex = explode($k, $str, 2); 
 $new_plus = array_slice($plus, $i, null, true);
 $l = $func_c2i($ex[0], $new_plus);
 $r = $func_c2i($ex[1], $new_plus);
 if($l == 0) $l = 1;
 return $l * $v + $r;
 }
 }
 
 return (int)$str;
 }
 return $func_c2i($str);
 }
 
 //来自uct php微信开发框架，其中的checkString函数如下
 function checkString($var, $check = '', $default = '') {
 if (!is_string($var)) {
 if(is_numeric($var)) {
 $var = (string)$var;
 }
 else {
 return $default;
 }
 }
 if ($check) {
 return (preg_match($check, $var, $ret) ? $ret[1] : $default);
 }
 
 return $var;
}

实现效果如下。

echo checkNatInt('九百六十万'); //普通中文数字，9600000
echo checkNatInt('壹亿柒仟万零捌佰肆拾'); //大写中文数字，170000840
 
 
echo checkNatInt('学好PHP拿百万年薪'); //句子中的数字, 1000000
echo checkNatInt('今年春运发送人次达26亿'); //数字和汉字混合出现，2600000000
 
echo checkNatInt('两只小蜜蜂'); //口语化数字，2
echo checkNatInt('万万没想到'); //复古的表达方式，100000000
