Code Inspection: Dangerous array initialization
Reports dangerous array initializations (such as
$arr = value).
This practice is discouraged because if
$arr already contains some value (for example, a string from a request variable), then this value will stay in place and
 may actually stand for string access operator. It is always preferable to initialize a variable by direct assignment.
See Creating/modifying with square bracket syntax (php.net) for details.
