first, the number is 0. If you want to automatically generate a number, automatically generate a number, such as the form of "d0000009", "d0000027", then you will face a problem, how to use the left 0 to make such a 8-digit code? I think of two

One, the number is 0. If you want to automatically generate a number, automatically generate So-and-so number, like this form of "d0000009", "d0000027", then you will face a problem, how to the left with 0 to make up the 8-digit code? I think of

Copy CodeThe code is as follows: $sourceNumber = "1";$newNumber = substr (Strval ($sourceNumber +1000), 1, 3);echo "$newNumber";?> This time it will appear: 001 If you want to increase the number of digits, you can increase the 1000 and then

Copy CodeThe code is as follows: $sourceNumber = "1"; $newNumber = substr (Strval ($sourceNumber +1000), 1, 3); echo "$newNumber"; ?> This time it will appear: 001 If you want to increase the number of digits, you can increase the 1000 and then
