twitter followers count with smallest number and with largest number of followers

Here is the function I wrote for all to convert your largest numbers into smallest number.

number_prefix function with 4 parameters $number used for number.

$perception parameter is used for digits are showing after . eg: default is 2 so the result will be 95.47

$prefixbetween parameter is used for after digit sign eg default is null and – (dash) can be passed so number will 95.75-M

$fullletter parameter default is false if on false it return M for Million when it true the number will be shown 95.75 Million

function number_prefix($number=0,$perception = 2,$prefixbetwen='',$fullletter=false){
	$number = preg_replace('/[^0-9.]/','',$number);  //numbers only 0 to 9 
	if(is_numeric($number)){
		$number = ltrim($number, '0'); //remove first zero eg: 061541
		$number = round($number); 	//remove eg 555.55	
	}
	
	$number = sprintf('%0.0f',$number);
	if($number>=1){
		$number_len = strlen($number);
		
		if($fullletter==false){
			$thousand = 'K';
