在PHP中返回布尔值时的最佳实践

Question

I noticed lately that eclipse is suggesting me the use of constants TRUE and FALSE from core.php when returning true or false from a function.

In other words should I use

function misc () 
{
    ...

    return true;
}

or

function misc () 
{
    ...

    return TRUE;
}

I know they are the same thing because of the way these constants are defined in core.php

define ('TRUE', true);
define ('FALSE', false);

So if anyone could explain what's best practice I would really appreciate.

Answer 1

Best practice is, if you do not have your own coding standard, to follow the FIG coding standards.

According to FIG PSR-2, there is no ambiguity what so ever about this particular issue:

The PHP constants true, false, and null MUST be in lower case.
