| Update Log: |
The step parameter was added in PHP 5.0. In versions from PHP 4.1.0 to 4.3.2, the function treats numeric strings as strings rather than integers. Numeric strings will be used for character sequences, for example, "5252" is considered as "5". Support for character sequences and descending arrays was added in PHP 4.1.0. The value of the character sequence is limited to a length. If the length is greater than one, only the first character is used. In versions prior to this, range() only generated ascending integer arrays. |
