/**
* Format numbers
*/
public function float_number($number){
$length = strlen($number); //Number length if($length > 8){ //Billion units $str = substr_replace(strstr($number,substr($number,-7),' '),'.',-1,0)."100 million";
}elseif($length >4){ //Ten thousand units //The first two are intercepted $str = substr_replace(strstr($number,substr($number,-3),' '),'.',-1,0)."Ten thousand";

Knowledge points expansion:
PHP number to capital amount (object-oriented version)
I have been searching online for a long time but haven't had a complete use, so I had to write it myself (the integer part of the effective digits reaches tens of trillions, and the decimal part reaches four decimal places)
$time_start=getmicrotime();
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}
/// CLASS BEGIN //
class Num2cny
{
/** Caps */
private $cny_num = array('zero','one','two','Ginseng','Si','Wu','land','Qi','eight','Nine');
/** Units of integer parts*/
private $cny_int_unit = array('round','pickup','Bai','thousand','Ten thousand','pickup','Bai','thousand','100 million','pickup','Bai','thousand','Ten thousand','pickup','Bai','thousand');
/** Units of decimal parts*/
private $cny_dec_unit = array('horn','point','Li','hour');
/** Is it greater than 1*/
private $greater_than_1 = FALSE;
/**
* Convert to capitalization amount.

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));// Filter out left and right spaces and commas$str = ltrim($str,'0');
$_integerStr = '';// Integer part number$_decimalStr = '';// Decimal number
