英文:
turn a number based on passed in value to at least 6 digit and max 8 digit
问题
public static function generateReceiptNumber(int $id)
{
$receipt_number = sprintf('%08d', $id % 100000000 + 1);
return $receipt_number;
}
英文:
public static function generateReceiptNumber(int $id){$receipt_number = sprintf('%06d', $id % 100000000);return $receipt_number;}
I am having the above code to help me to transform a passed in $id to a minimum 6 digit and maximum 8 digit number. eg: 000001 - 99999999
But this code has a flaws that when the $id equal to 100000000, it will return me 000000,
how can i enhance the code above to give me 000001 instead?
So and so forth, the $id is the database incremental id.
The purpose of wanted to achieve this is because, i have a display text box which the text limit is only 8 digit, i can only restarted the number back to 000001 and continue the count to repeat.
答案1
得分: 3
function generateReceiptNumber(int $id){while($id >= 100000000)$id -= 100000000 - 1;return sprintf('%06d', $id);}
英文:
How about this:
function generateReceiptNumber(int $id){while($id>=100000000)$id -= 100000000 - 1;return sprintf('%06d', $id);}
答案2
得分: 0
public static function generateReceiptNumber(int $id)
{
// 处理特殊情况，当 $id 为 100000000 时
if ($id === 100000000) {
return '000001';
}
// 使用取模运算将 ID 限制在范围 0 到 99,999,999$limited_id = $id % 100000000;// 使用前导零格式化限制后的 ID，确保至少有 6 位数字$receipt_number = sprintf('%06d', $limited_id);return $receipt_number;
}
英文:
public static function generateReceiptNumber(int $id){// Handle the special case when $id is 100000000if ($id === 100000000) {return '000001';}// Use modulo to limit the ID to the range 0 to 99,999,999$limited_id = $id % 100000000;// Format the limited ID with leading zeros to ensure at least 6 digits$receipt_number = sprintf('%06d', $limited_id);return $receipt_number;}
