你知道这个PHP命令行选项解析库(pflag)吗？

    'descNlOnOptLen' => 26]);// ...

use ToolkitPFlagFlagOption;use ToolkitPFlagFlagType;use ToolkitPFlagValidatorEnumValidator;// add options// - quick add$fs->addOpt('age', 'a', 'this is a int option', FlagType::INT);// - 使用字符串规则快速添加选项定义$fs->addOptByRule('name,n', 'string;this is a string option;true');// -- 一次添加多个选项$fs->addOptsByRules([
    'tag,t' => 'strings;array option, allow set multi times',
    'f'     => 'bool;this is an bool option',]);// - 使用数组定义/** @see Flags::DEFINE_ITEM for array rule */$fs->addOptByRule('name-is-very-lang', [
    'type'   => FlagType::STRING,

    'validator' => EnumValidator::new(['one', 'two', 'three']),]);// - 使用 Option 对象$opt = Option::new('str1', "this is  string option, ndesc has multi line, nhaha...");$opt->setDefault('defVal');$fs->addOption($opt);

use ToolkitPFlagFlagArgument;use ToolkitPFlagFlagType;// add arguments// - quick add$fs->addArg('strArg1', 'the is string arg and is required', 'string', true);// - 使用字符串规则快速添加定义$fs->addArgByRule('intArg2', 'int;this is a int arg and with default value;no;89');// - 使用 Argument 对象$arg = Argument::new('arrArg');// OR $arg->setType(FlagType::ARRAY);$arg->setType(FlagType::STRINGS);$arg->setDesc("this is an array arg,n allow multi value,n must define at last");$fs->addArgument($arg);
