如何在PHP中为var编写长数字？

Question

I have a constant with 8 zeros. How write it in var with good readability?

java way:

int number = 100_000_000;

Have PHP something similar?

Not the way you expose it. Recently a RFC (request for comments) has been proposed to address a solution to this, but this proposal has been rejected. See https://wiki.php.net/rfc/number_format_separator

However you still can write it this way : $var = 10e7;
