In some situations, the union operator ( ) might be more useful to you than array_merge.The array_merge function does not preserve numeric key values.
If the version shows anything other than 126.96.36.199, then the file has not been updated.
The following steps should resolve this problem: If this fails to resolve the issue, or you are certain you are not running the backburner service, then the problem is likely just due to a corruption of the 3ds max files.
However, if one parameter is null it PHP will not only return null for the entire function but will also (not always) raise an error, such as : [ Warning: array_merge(): Argument #x is not an array...
]This error message won't appear if the defective variable is an empty array (an empty array is still an array), but it will result in an undesirable incomplete Array.
NOTE: The 3ds max 5.1 demo CD will work as a fully functional version.
