我正在撰写一份PHP报告，该报告旨在使用commma分隔符纯粹作为CSV文件导出。
有三列与product_id相关，这三列如下：
SKU Parent / Child Parent SKU
12345 parent 12345
12345_1 child 12345
12345_2 child 12345
12345_3 child 12345
12345_4 child 12345
18099 parent 18099
18099_1 child 18099
这是指完整CSV文件的链接：

目前代码如下：
$sql = "select * from product WHERE on_amazon = 'on' AND active = 'on'";
$result = mysql_query($sql) or die ( mysql_error() );?>
<?
// set headers
echo "

所以目前这只是将product_ID回显到SKU列。代码需要将product_id输入到数组中并检查它是否是唯一的。如果product_id对于数组是唯一的，则product_id将不加改变地回显，并且父项将回显给父母/子女＆＃39;列然后将product_id重复到父SKU＆＃39;柱。
但是，如果检查了数组并且数组中已存在product_id，则product_id将回显到＆＃39; SKU＆＃39;带后缀的列，即_1。那么孩子就会回应父母与孩子的关系。列和原始父product_id回显给父母SKU＆＃39;柱。
但是 - 同一个SKU不能用相同的后缀重复，即12345_1,12345_1 - 所以可能会有另一个阵列用于检查后缀SKU。
如果有人可以提供帮助，那就太好了。 感谢

我自己设法解决了这个问题，并认为我会分享我的解决方案以供将来参考。
/*

* If unique product_id becomes parent SKU
* If not product_id becomes child of previous parent and suffixed with _1, _2 etc...
*/

$SKU[] = $line['product_id'];
