note 49221 deleted from function.array-merge by salathe

Note Submitter: Alec Solway ---- Note that if you put a number as a key in an array, it is eventually converted to an int even if you cast it to a string or put it in quotes. That is: $arr["0"] = "Test"; var_dump( key($arr) ); will output int(0). This is important to note when merging because array_merge will append values with a clashing int-based index instead of replacing them. This kept me tied up for hours.
