Description:
------------
This seems to be a design error rather than a bug: parse_ini_file() does not provide any way to handle errors gracefully. In the event of a syntax error, it throws an E_WARNING *but* the return value is simply an empty array (the same as a - valid - empty file) instead of FALSE. Thus there is no way to trap the error (via @ prefix) and handle it in a more graceful way than an E_WARNING.

I would argue that changing the return value to FALSE in the case of an invalid file is a reasonable change, since the only situations it will break are ones where currently PHP throws a warning anyway.


Reproduce code:
---------------
This is what it would be nice to be able to do:

$ini = @parse_ini_file('some_invalid.ini');
if ($ini === false) {
   // error: do something graceful
}
// normal execution

Expected result:
----------------
The code section "// do something graceful" executes

Actual result:
--------------
The code section "// normal execution" executes
