function ExchangeMoney($N_money) { $A_tmp=explode(".",$N_money ); //将数字按小数点分成两部分,并存入数组$A_tmp $I_len=strlen($A_tmp[0]); //测出小数点前面位数的宽度 if($I_len%3==0) { $I_step=$I_len/3; //如前面位数的宽度mod 3 = 0 ,可按,分成$I_step 部分 }else { $step=($len-$len%3)/3+1; //如前面位数的宽度mod 3 != 0 ,可按,分成$I_step 部分+1 }
$C_cur=""; //对小数点以前的金额数字进行转换 while($I_len<>0) { $I_step--;
if($I_step==0) { $C_cur .= substr($A_tmp[0],0,$I_len-($I_step)*3); }else { $C_cur .= substr($A_tmp[0],0,$I_len-($I_step)*3).","; }
$A_tmp[0]=substr($A_tmp[0],$I_len-($I_step)*3); $I_len=strlen($A_tmp[0]); }
//对小数点后面的金额的进行转换 if($A_tmp[1]=="") { $C_cur .= ".00"; }else { $I_len=strlen($A_tmp[1]); if($I_len<2) { $C_cur .= ".".$A_tmp[1]."0"; }else { $C_cur .= ".".substr($A_tmp[1],0,2); } } //加上人民币符号并传出 $C_cur="¥".$C_cur; return $C_cur; } |
