- convert from int to chinese string e.g. 125 -> 一百二十五
function numToWord($num){
$chiNum = array('零', '一', '二', '三', '四', '五', '六', '七', '八', '九');

$last_flag = true; // pervious number is 0?
$zero_flag = true; // first number?
$temp_num = null;
if ($count == 2) { // 2 digit number
$temp_num = $num_str[0];
$chiStr = $temp_num == 1 ? $chiUni[1] : $chiNum[$temp_num].$chiUni[1];

}
}else{

}
2. convert from chinese string into int, eg. 一百二十五 > 125
function cn2num($string){
if(is_numeric($string)){
return $string;
}
// '仟' => '千','佰' => '百','拾' => '十',
$string = str_replace('仟', '千', $string);
$string = str_replace('佰', '百', $string);
$string = str_replace('拾', '十', $string);
$num = 0;
$wan = explode('萬', $string);
if (count($wan) > 1) {
$num += cn2num($wan[0]) * 10000;
$string = $wan[1];
}
$qian = explode('千', $string);
if (count($qian) > 1) {
$num += cn2num($qian[0]) * 1000;
$string = $qian[1];
}
$bai = explode('百', $string);
if (count($bai) > 1) {
$num += cn2num($bai[0]) * 100;
$string = $bai[1];
}
$shi = explode('十', $string);
if (count($shi) > 1) {
$num += cn2num($shi[0] ? $shi[0] : '一') * 10;
$string = $shi[1] ? $shi[1] : '零';
}
$ling = explode('零', $string);
if (count($ling) > 1) {
$string = $ling[1];
}
$d = 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, '0' => 0, 'O' => 0, 'o' => 0,
'两' => 2
);
return $num + @$d[$string];
