php - 用于拆分服装尺寸的正则表达式

Question

我有以下输入（仅例如，真实输入包含更多疯狂的数据）

$values = [
    '32/34, 36/38, 40/42, 44/46',
    '40/42/44/46/48',
    '58/60',
    '39-42',
    '40-50-60',
    '24-25,26,28,30',
    '36 40,5 44',
];

并希望通过分隔符拆分它，例如/or,但保留成对的值。仅当分隔符未多次出现时才应执行此操作，因此结果应如下所示：

'32/34, 36/38, 40/42, 44/46'
    => [ '32/34', '36/38', '40/42', '44/46' ]
'40/42/44/46/48'
    => [ '40', '42', '44', '46', '48' ]
'58/60'
    => [ '58/60' ]
'39-42'
    => [ '39-42' ]
'40-50-60'
    => [ '40', '50', '60' ]
'24-25,26,28,30'
    => [ '24-25', '26', '28', '30' ]
'36 40,5 44'
    => [ '36', '40,5', '44' ]

到目前为止我所拥有的是

$separator = '^|$|[\s,\/-]';
$decimals = '\d+(?:[,.][05])?';
foreach ($values as $value) {
    preg_match_all('/' .
        '(?<=' . $separator . ')' .
        '(?:' .
            '(?P<var1>(' . $decimals . ')[\/-](?-1)|(?-1))' .
        ')(?=' . $separator . ')' .
    '/ui', $value, $matches);
    print_r($matches);
}

但这失败了40/42/44/46/48返回

[var1] => Array
    (
        [0] => 40/42
        [1] => 44/46
        [2] => 48
    )

但是每个数字都应该单独返回。修改正则表达式'(?P<var1>(' . $decimals . ')([\/-])(?-2)|(?-2))(?!\3)'更好，但仍然返回错误的结果

[var1] => Array
    (
        [0] => 40
        [1] => 42
        [2] => 44
        [3] => 46/48
    )

正确的正则表达式应该如何？
