My code has some long constant numbers. To avoid mistakes, I want to declare numbers with thousand separators. In Java 7, I can do this:
int MyConst = 1_000_000; ///The token '_' (thousand separator) make it more clearance
How can I do that in PHP?
PHP does not offer such feature. See: http://www.php.net/manual/en/language.types.integer.php
You could use scientific notation to represent big numbers: http://www.php.net/manual/en/language.types.float.php but then again, your integers would be actually floats and you'd probably have to add typecasting.
