Coding standard does not specify negation formatting #48

Description

@mhujer

Currently the negation formatting is not explicitly specified in the standard.

It can be written either:

  • with no spaces if (!is_array($foo))
  • with space after if (! is_array($foo))
  • with spaces around if ( ! is_array($foo))

In the Scalar types chapter there is a code example which includes negation formatted without spaces around:

<?php

if (!is_int($foo)) {
	return (int) $foo;
}

So it would be nice to have it explicitly stated in the coding standard. Maybe eventually also checked automatically (but PHP_CodeSniffer currently offers only SpaceAfterNotSniff).
