One more example, what problem this "bug/behavior" may cause: $value1 = 345.654; $value2 = 345.655; $array = array(); $array[$value1] = $value1; $array[$value2] = $value2; Result: array ( 345 => 345.655, ) If this is a normal behavior you should put a note about this in the manual. Previous Comments: ------------------------------------------------------------------------ [2005-04-11 16:19:04] marek at lewczuk dot com Description: ------------ Suppose we have a float value: $value = 345.332 and we want to use this value as an array key: $array[$value] = $value. This will cause that key will be truncated to integer 345 not to string "345.332". It is written in the manual that: "...A key may be either an integer or a string. If a key is the standard representation of an integer, it will be interpreted as such (i.e. "8" will be interpreted as 8, while "08" will be interpreted as "08")..." >From this point of view floats should be converted to strings. I'm not saying that this is a bug, rather I would like to be sure if this is a proper behavior. Simple solution is to type cast float value to string (string), but we have to know that given value is a float (and sometimes, we don't know that). IMHO any other type than integer should be treat as string. Reproduce code: --------------- $value = 345.654; $array = array(); $array[$value] = "Float"; Expected result: ---------------- array ( "345.654" => "Float" ) Actual result: -------------- array ( "345" => "Float" ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32671&edit=1
