PHP實現漢字轉整型數字，如：一百零一 轉成101

test();
/**


測試
*/
function test() {
 echo CnToInt('一'); // 1
 echo CnToInt('十'); // 10
 echo CnToInt('十一'); // 11
 echo CnToInt('一百一十'); // 110
 echo CnToInt('一千零一'); // 1001
 echo CnToInt('一萬零一百零一'); // 10101
 echo CnToInt('一億一千三百萬零三千零一'); // 113003001
 echo CnToInt('一千萬億'); // 11.0E+15
}

/**

@param String $var 需要解析的中文數
@param Int $start 初始值
@return int
*/
