| PHP Version: | 4+ |
| PHP Changelog: | The step parameter was added in PHP 5.0. In PHP versions 4.1.0 through 4.3.2, this function sees numeric strings as strings and not integers. The numeric strings will be used for character sequences, e.g., "5252" is treated as "5". Support for character sequences and decrementing arrays was added in PHP 4.1.0. Character sequence values are limited to a length of one. If the length is higher than one, only the first character is used. Before this version, range() only generated incrementing integer arrays. |
