常见的想当然
Serializing an ArrayInput instance to a CLI string with __toString() produces argument tokens that preserve boolean flag states and option values when round-tripped through StringInput.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- ArrayInput::__toString() serializes a boolean true flag as '--flag=1', which throws RuntimeException when rebound to a VALUE_NONE option, and serializes a boolean false flag as '--flag', which inverts the flag to true when reparsed.
- ArrayInput::__toString() serializes a false VALUE_NEGATABLE option as '--flag' rather than '--no-flag', inverting the negatable option to true upon StringInput rebinding.
- ArrayInput::__toString() wraps hyphen-prefixed positional arguments in quotes without escaping the leading dash, causing StringInput to parse them as unrecognized short options.
- ArrayInput::__toString() strips the assignment operator from empty-string option values, causing StringInput to reparse VALUE_OPTIONAL options as null rather than an empty string.
- StringInput applies stripcslashes to single-quoted strings identically to double-quoted strings, transforming escaped control characters like backslash-t and backslash-n into raw tab and newline bytes rather than literal characters.
- ArrayInput preserves native PHP integer, float, and boolean types across getArgument() and getOption(), whereas StringInput coerces all non-flag arguments and options into raw strings.
