| Update log: | The step parameter is new in PHP 5.0. In PHP versions 4.1.0 to 4.3.2, this function treats numeric strings as strings instead of integers. Numeric strings will be used for character sequences, for example, "5252" is treated as "5". Support for character sequences and descending arrays was new in PHP 4.1.0. Character sequence values are limited to a length. If the length is greater than one, only the first character is used. Prior to this version, range() only produced increasing arrays of integers. |
