Function written in php to convert RMB numbers to RMB capital letters

Sometimes we need to randomly generate usernames and passwords in applications, which can greatly improve the security of the application. To generate random usernames and passwords in PHP, you can use the mt_rand function or the rand function. The application of the rand function in verification codes More, and generating long character random codes generally requires the mt_rand function.

Using PHP to generate random numbers can be applied in many places, such as designing random passwords for programs, applications for simulating dice games, rock-paper-scissors game applications, etc.

The following are two functional methods for generating random numbers in PHP:

I saw a very interesting PHP function on the Internet that converts RMB amount numbers into Chinese uppercase letters. The essence is to convert numbers into Chinese uppercase letters. I tested it and it was very interesting. Just enter any number and you can print it out in uppercase letters. Novice friends, give it a try and draw inferences from one example. You can also write many interesting PHP conversion functions. PHP code:

<?     
function cny($ns) {    
    static $cnums=array("零","壹","贰","叁","肆","伍","陆","柒",
"捌","玖"),    
        $cnyunits=array("圆","角","分"),    
        $grees=array("拾","佰","仟","万","拾","佰","仟","亿");
    list($ns1,$ns2)=explode(".",$ns,2);    
    $ns2=array_filter(array($ns2[1],$ns2[0]));    
    $ret=array_merge($ns2,array(implode("",_cny_map_unit(str_spl
it($ns
1),$grees)),""));    
    $ret=implode("",array_reverse(_cny_map_unit($ret,$cnyunits)));
    return str_replace(array_keys($cnums),$cnums,$ret);
}
function _cny_map_unit($list,$units) {    
    $ul=count($units);    
    $xs=array();    
    foreach (array_reverse($list) as $x) {
        $l=count($xs);    
        if ($x!="0" || !($l%4)) $n=($x==&#39;0&#39;?&#39;&#39;:$x).($units[($l-1)
%$ul]);    
        else $n=is_numeric($xs[0][0])?$x:&#39;&#39;;
        array_unshift($xs,$n);    
    }    
    return $xs;    
}   
?>

Usage: Just pass the numeric parameters directly. In the example below, the numbers are printed in uppercase letters. Output: 10,000,200,100,211 yuan

PHP code

<?php   
 echo cny(&#39;12121&#39;);   
?>
