PHP program to convert China Merchants Bank credit card repayment date into Chinese date

This program outputs the Chinese date as 2001-12-23, and solves the problem of "ten" very well, such as the processing of "ten" in "Eleven" and "Twenty-one"! It can be changed to a function with slight modifications.
$str="December 23, 2001";
echo $str."

";
$flag=0;
$cn=array("一" ,"two","three","four","five","six","seven","eight","nine","ten","zero","○");
$num= array("1","2","3","4","5","6","7","8","9","","0","0");
$len=strlen($str);
for ($i=0;$i<$len;$i+=2)
{
$array_str[$i]=substr($str,$i,2);
$cout=0;
while($cout {
if ($array_str[$i]==$cn[$cout])
{
if ($flag==1)
echo "-"; "if (($ array_str [$ i] ==" ten ") and ($ flag == 1)
{
$ temp [$ count] =" 1 "; cout];
             $flag=2;break;
}
else
