解析一个包含商品变体信息的字符串，并将其转换为结构化的数组格式。

解析一个包含商品变体信息的字符串，并将其转换为结构化的数组格式。

parse_variations 函数接收一个字符串 $variations_str，该字符串包含多个商品变体的信息，每个变体由 ||| 分隔。每个变体的信息又由 @@@ 分隔成多个部分，包括属性、价格、库存、SKU、图片等。

<?php

$attributes = explode('@@@',$attributeses);
$attributes0 = explode('###',$attributes[0]);
foreach ($attributes0 as $atts){
@list ($name,$val) = explode('::',$atts);
$current[$name]=$val;
}

$variations[] = [
'attributes' => $current,
'regular_price' => $attributes[1] ?? '', // 原价
'sale_price' => $attributes[2] ?? '', // 促销价

'images' => isset($attributes[6]) ? explode('###', $attributes[6]) : [], // 图片
'download_url' => $attributes[7] ?? '' // 下载地址
];

}
return [$variations];

};

$result = parse_variations($variations_str);
print_r($result);

解析后输出
