今天要批量生成一批合同号,遇到问题了,比如说
start=0066812~end=0066818

for ($start;$start 除了0066812之外,后面的全将00给去掉了,请问有什么方法可以保留住0的??


回复讨论(解决方案)

$start = 66812;$end = 66818;for ($start;$start<=$end;$start++){  $s = sprintf('%07d', $start);  echo $s . '<br>';}

$start = 66812;$end = 66818;for ($start;$start<=$end;$start++){  $s = sprintf('%07d', $start);  echo $s . '<br>';}

赋值的时候一定要是
$start = 0066812;
$end = 0066818;
前边有两个0
因为还有种可能是009999到010000,反正09过了就是10,前边就不是两个0了

有什么区别吗?

$start = '0066812';$end = '0066818'; for ($start;$start<=$end;$start++){  $s = sprintf('%07d', $start);  echo $s . '<br>';}

0066813
0066814
0066815
0066816
0066817
0066818


但是如果写作 $start = 0066812;
那就是八进制数,全完蛋了
