除了存在变量反转之外,我有两个几乎相同的函数。我想知道如何在没有重复代码的情况下处理这个问题。
例如:
public static function getMajorRelative($tonality){
$result = array_search($tonality,self::$_minorTonalities);
return self::$_majorTonalities[$result];
}
和
public static function getMinorRelative($tonality){
$result = array_search($tonality,self::$_majorTonalities);
return self::$_minorTonalities[$result];
}
任何人都有类似的受孕问题吗?
谢谢,

您始终可以传入要从以下位置接收结果的数组:
public static function getRelative($tonality, $return_array) {
//If returning minor, search major; Else, search minor.
$array_to_search = ($return_array === self::$_minorTonalities ? self::$_majorTonalities : $_minorTonalities);
$result = array_search($tonality, $array_to_search);
return $return_array[$result];
}

2条相似(不完全相同)的代码行并不是真正的重复,但您可以这样做:
protected static function getRelative($tonality, $tonalities1, $tonalities2) {
$result = array_search($tonality, $tonalities1);
return $tonalities2[$result];
}
public static function getMajorRelative($tonality){
return self::getRelative($tonality, self::$_minorTonalities, self::$_majorTonalities);
}
public static function getMinorRelative($tonality){
return self::getRelative($tonality, self::$_majorTonalities, self::$_minorTonalities);
}
如果真的很重要
如果您的数组中没有$ tonality的值,您可能还需要一些异常处理

我不确定还有很多需要改进的地方。但如果你愿意,你可以把它写成一个函数:
public static function getRelative($chord,$tonality)
{
$varName = '_'.($chord == 'major' ? 'major' : 'minor').'Tonalities';
$result = array_search($tonality,self::${$varName});
return self::${$varName}[$result];
}
您可以将其命名为:
getRelative('major',$tonality);
getRelative('minor',$tonality);
