php实现数字格式化,数字每三位加逗号的功能函数,具体代码如下:

function num_format($num){ 
 if(!is_numeric($num)){ 
  return false; 
 } 
 $num = explode('.',$num);//把整数和小数分开 
 $rl = $num[1];//小数部分的值 
 $j = strlen($num[0]) % 3;//整数有多少位 
 $sl = substr($num[0], 0, $j);//前面不满三位的数取出来 
 $sr = substr($num[0], $j);//后面的满三位的数取出来 
 $i = 0; 
 while($i <= strlen($sr)){ 
  $rvalue = $rvalue.','.substr($sr, $i, 3);//三位三位取出再合并,按逗号隔开 
  $i = $i + 3; 
 } 
 $rvalue = $sl.$rvalue; 
 $rvalue = substr($rvalue,0,strlen($rvalue)-1);//去掉最后一个逗号 
 $rvalue = explode(',',$rvalue);//分解成数组 
 if($rvalue[0]==0){ 
  array_shift($rvalue);//如果第一个元素为0,删除第一个元素 
 } 
 $rv = $rvalue[0];//前面不满三位的数 
 for($i = 1; $i < count($rvalue); $i++){ 
  $rv = $rv.','.$rvalue[$i]; 
 } 
 if(!empty($rl)){ 
  $rvalue = $rv.'.'.$rl;//小数不为空,整数和小数合并 
 }else{ 
  $rvalue = $rv;//小数为空,只有整数 
 } 
 return $rvalue; 
}

另外可以使用系统自带的函数string number_format ( float number [, int decimals [, string dec_point, string thousands_sep]] ):

例子:

echo number_format('169856420'); 
Copy after login

输出结果将为:169,856,420

echo number_format('1000000',2); 
Copy after login

输出结果将为:1,000,000.00

echo number_format('1000000',2,',','.'); 
Copy after login

输出结果将为:1.000.000,00

以上就是php实现数字每三位加逗号的代码,刚开始大家看到题目是不是没有思路,小编也是的,希望通过这篇文章可以给大家一些启发。
