程序如：
number_format.php :
<?php $number = 1234.56; $english_format_number = number_format($number); echo $english_format_number; ?>


php number_format.php 1,235

用正则的方法进行分割：
<?php     function format_count($count){/* 千位符号 */         if($count/1000 >= 1){             $count = preg_replace('/(?<=[0-9])(?=(?:[0-9]{3})+(?![0-9]))/', ',', $count);         }         return $count;     }     $count = 1234.56;     echo format_count($count);
---------- 调试PHP ----------
1,234.56
输出完成 (耗时 0 秒) - 正常终止


要把SQL查询出来的数值以下面的方法显示  
  1122222.21   显示为1,122,222.21  
  用number_format函数这么写啊？！  
  
  各位最好给个代码，谢谢

$number=1122222.21;  
  echo   number_format($number,   2,   ".",   ",");

我需要：
<?php //$num = 12345678.9; $num = 12345678; echo   number_format($num,   0,   "",   ","); ?>

$result=array("day_key"=>$rs->fields['day_key'],"week"=>$rs->fields['week'],"pv"=>number_format($rs->fields['pv'],   0,   "",   ","),"uip"=>number_format($rs->fields['uip'],   0,   "",   ","),"reg_member"=>number_format($rs->fields['reg_member'],   0,   "",   ","),"upload_ct"=>number_format($rs->fields['upload_ct'],   0,   "",   ","),"play_ct"=>number_format($rs->fields['play_ct'],   0,   "",   ","),"video_total"=>number_format($rs->fields['video_total'],   0,   "",   ","),"play_time"=>number_format($rs->fields['play_time'],   0,   "",   ","));

首个字母大写：
<?php $name ="jackxiang"; echo ucfirst($name); ?>
执行后，如下：
root@116.255.139.240:/home/admin/php# php ucfirst.php Jackxiang
