PHP Digital Conversion Chinese character code (algorithm) _php tips

Copy Code code as follows:

Converts a number to Chinese characters, such as 1210 to 1210
$num = "842105580";//Nine digits
function Del0 ($num)//Remove 0 before the number segment
{
Return "". Intval ($num);
}
function n2c ($x)//single digit variable kanji
{
$arr _n = Array ("0", "one", "two", "three", "four", "five", "six", "seven", "eight", "Nine", "ten");
return $arr _n[$x];
}
function Num_r ($ABCD)//Read value (4-bit)
{
$arr = Array ();
$str = ""; Number of Chinese characters after reading
$flag = 0; Whether the bit is zero
$flag _end = 1; Whether to end with "0"
$size _r = strlen ($ABCD);
for ($i =0; $i < $size _r; $i + +)
{
$arr [$i] = $ABCD {$i};
}
$arrlen = count ($arr);
for ($j =0; $j < $arrlen; $j + +)
{
$ch = N2C ($arr [$arrlen-$j]); Turn the characters from the back forward
echo $ch;
echo "";
if ($ch = = "0" && $flag = = 0) {//if the first 0
$flag = 1; The bit is zero
$str = $ch. $str; Add Chinese character value string
Continue
}elseif ($ch = = "0") {//If not the first zero
Continue
}
$flag = 0; The bit is not 0
Switch ($j) {
Case 0: $str = $ch; $flag _end = 0; Break First (end), not ending with "0"
Case 1: $str = $ch. " X. $STR; Break Second place
Case 2: $str = $ch. " Hundred ". $str; Break Third place
Case 3: $str = $ch. " Thousand ". $str; Break Fourth place
}
}
if ($flag _end = = 1)//If ending with "0"
{
Mb_internal_encoding ("UTF-8");
$str = mb_substr ($str, 0, Mb_strlen ($str)-1); Get rid of "0."
}
return $str;
}

{
$num _real = del0 ($num);//Remove front "0"
$numlen = strlen ($num _real);
