php to convert Chinese to numbers (easy to use for testing)

Share an auxiliary function, use PHP to identify the numbers in the string as much as possible,

First enter the code

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;
}

The effect is as follows.

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
