php数字转汉字代码(算法)，学习php的朋友可以参考下。

//将数字转换为汉字，比如1210转换为一千二百一十$num = "842105580";//九位数function del0($num) //去掉数字段前面的0{return "".intval($num);}function n2c($x) //单个数字变汉字{$arr_n = array("零","一","二","三","四","五","六","七","八","九","十");return $arr_n[$x];}function num_r($abcd) //读取数值（4位）{$arr= array();$str = ""; //读取后的汉字数值$flag = 0; //该位是否为零$flag_end = 1; //是否以“零”结尾$size_r = strlen($abcd);for($i=0; $i<$size_r; $i++){$arr[$i] = $abcd{$i};}$arrlen = count($arr);for($j=0; $j<$arrlen; $j++){$ch = n2c($arr[$arrlen-1-$j]); //从后向前转汉字echo $ch;echo "";if($ch == "零" && $flag == 0){ //如果是第一个零$flag = 1; //该位为零$str = $ch.$str; //加入汉字数值字符串continue;}elseif($ch == "零"){ //如果不是第一个零了continue;}$flag = 0; //该位不是零switch($j) {case 0: $str = $ch; $flag_end = 0; break; //第一位（末尾），没有以“零”结尾case 1: $str = $ch."十".$str; break; //第二位case 2: $str = $ch."百".$str; break; //第三位case 3: $str = $ch."千".$str; break; //第四位}}if($flag_end == 1) //如果以“零”结尾{mb_internal_encoding("UTF-8");$str = mb_substr($str, 0, mb_strlen($str)-1); //把“零”去掉}return $str;}function num2ch($num) //整体读取转换{$num_real = del0($num);//去掉前面的“0”$numlen = strlen($num_real);echo "numlen=".$numlen."";if($numlen >= 9)//如果满九位，读取“亿”位{$y=substr($num_real, -9, 1);//echo $y;$wsbq = substr($num_real, -8, 4);$gsbq = substr($num_real, -4);$a = num_r(del0($gsbq));$b = num_r(del0($wsbq))."万";$c = num_r(del0($y))."亿";}elseif($numlen <= 8 && $numlen >= 5) //如果大于等于“万”{$wsbq = substr($num_real, 0, $numlen-4);$gsbq = substr($num_real, -4);$a = num_r(del0($gsbq));$b = num_r(del0($wsbq))."万";$c="";}elseif($numlen <= 4) //如果小于等于“千”{$gsbq = substr( $num_real, -$numlen);$a = num_r(del0($gsbq));$b="";$c="";}$ch_num = $c.$b.$a;return $ch_num;}echo $num.""; //数字echo num2ch($num); //汉字echo "";echo num2ch("1240");
