访问量php对数字进行万。亿的转化
/**
* 格式化数字
*/
public function float_number($number){
$length = strlen($number); //数字长度
if($length > 8){ //亿单位
$str = substr_replace(strstr($number,substr($number,-7)," "),".",-1,0)."亿";
}elseif($length >4){ //万单位
//截取前俩为
$str = substr_replace(strstr($number,substr($number,-3)," "),".",-1,0)."万";
}else{
return $number;
}
return $str;
}

PHP 数字转为大写金额(面向对象版)
本人在网上找了很久都没个完整能用的，于是只好自己写个(有效位数整数部分至千万亿，小数部分至小数点后四位)
$time_start=getmicrotime();
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}
/// CLASS BEGIN //
class Num2cny
{
/** 大写数字*/
private $cny_num = array("零","壹","贰","参","肆","伍","陆","柒","捌","玖");
/** 整数部分的单位*/
private $cny_int_unit = array("圆","拾","佰","仟","万","拾","佰","仟","亿","拾","佰","仟","万","拾","佰","仟");
/** 小数部分的单位*/
private $cny_dec_unit = array("角","分","厘","毫");
/** 大于1吗*/
private $greater_than_1 = FALSE;
/**
* 转为大写金额。
* @access public
* @param string
* @return string
*/
public function conversion($str) {
if(empty($str))
{
return "Please input a numeric value!";
}
if( ! is_numeric($str))
{
return "It is not a numeric value!";
}
$str = str_replace(",","",trim($str));// 过滤掉左右空格和逗号
$str = ltrim($str,"0");
$_integerStr = "";// 整数部分数字
$_decimalStr = "";// 小数部分数字
