PHP algorithm-Converts a numeric amount to an uppercase amount

Recently looking at some of the PHP algorithm problems, encountered a digital amount converted to uppercase amount of small algorithm problem, here to post an example of their own.

Note: This small algorithm applies to amounts within 100,000.

<?php//$num = 12345.67;functionRmb_upper ($num){    $num=round($num, 2);//take two decimal places    $num= '.$num;//Convert to Digital    $arr=Explode(‘.‘,$num); $str _left=$arr[0];//12345    $str _right=$arr[1];// the    $len _left=strlen($str _left);//the length to the left of the decimal    $len _right=strlen($str _right);//the length//loop to the right of the decimal point converts the string to an array,     for($i= 0;$i<$len _left;$i++)    {        $arr _left[] =substr($str _left,$i, 1); }    //Print_r ($arr _left); Output:array ([0] = 1 [1] = 2 [2] = 3 [3] = 4 [4] = 5)     for($i= 0;$i<$len _right;$i++)    {        $arr _right[] =substr($str _right,$i, 1); }    //Print_r ($arr _right); Output:array ([0] = 6 [1] = 7)//construct array $daxie    $daxie=Array(        ' 0 ' = ' 0 ', ' 1 ' = ' one ', ' 2 ' + ', ' 3 ' = ' three ', ' 4 ' = ' ', ' 5 ' = ', ' 6 ' ' + ' land ', ' 7 ' = ' seven ', ' 8 ' = ' ' ba ', ' 9 ' = ' nine ',    ); //loops Replace the values in the array $arr_left with uppercase    foreach($arr _left  as $k=$v)    {        $arr _left[$k] =$daxie[$v]; Switch($len _left--)        {            //value is appended to the amount unit             Case5:$arr _left[$k]. = ' million '; Break;  Case4:$arr _left[$k]. = ' thousand '; Break;  Case3:$arr _left[$k]. = ' hundred '; Break;  Case2:$arr _left[$k]. = ' ten '; Break; default:$arr _left[$k]. = ' Yuan '; Break; }    }    //Print_r ($arr _left); Output:array ([0] = one million [1] = [+] [2] = three hundred [3] = ten [4] = dollar)    foreach($arr _right  as $k=$v)    {        $arr _right[$k] =$daxie[$v]; Switch($len _right--)        {             Case2:$arr _right[$k]. = ' angle '; Break; default:$arr _right[$k]. = ' points '; Break; }    }    //Print_r ($arr _right); Output:array ([0] = land angle [1] = seven)//convert the array into strings and stitch together    $new _left_str=implode(‘‘,$arr _left); $new _right_str=implode(‘‘,$arr _right); $new _str=$new _left_str.$new _right_str; //echo $new _str; Output: ' One million and three hundred ten Wu Yuanlu cents '//If the amount is 0, the uppercase string will have ' 10 ', such a string, need to replace    $new _str=Str_replace(' 0 ', ' 0 ',$new _str); $new _str=Str_replace(' 0 ', ' 0 ',$new _str); $new _str=Str_replace(' 0 ', ' 0 ',$new _str); $new _str=Str_replace(' 10 ', ' 0 ',$new _str); $new _str=Str_replace(' 000 ', ' 0 ',$new _str); $new _str=Str_replace(' 00 ', ' 0 ',$new _str); $new _str=Str_replace(' 0 yuan ', ' yuan ',$new _str); //echo ' <br/> ';    return $new _str;}EchoRmb_upper (12345.67);
