Question

我在php中设置了数组。我需要从下面的代码中删除重复/包含记录。

Array ( 
    [0] => Array ( [percent] => 88.461538461538 [basenum] => 079 [code] => HL [group] => 0 )
    [1] => Array ( [percent] => 88.461538461538 [basenum] => 097 [code] => HL [group] => 0 )
    [2] => Array ( [percent] => 88.461538461538 [basenum] => 709 [code] => HL [group] => 0 )
    [3] => Array ( [percent] => 88.461538461538 [basenum] => 790 [code] => HL [group] => 0 )
    [4] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => HL [group] => 0 )
    [5] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => TL [group] => 0 ) // This will not removed because of 'code' different in array
    [6] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => HL [group] => 1 ) // This will not removed because of 'group' different in array
))

由于元素0中包含basenum，因此将删除元素1,2,3,4,5。因此，预期结果/新数组应为

Array (
    [0] => Array ( [percent] => 88.461538461538 [basenum] => 079 [code] => HL [group] => 0 ) 
    [1] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => TL [group] => 0 )
    [2] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => HL [group] => 1 )
)

感谢所有答案。

由于basenum值相等，如果它们包含相同的字符集，则此代码将执行您想要的操作。 compare_basenum通过对两个basenum中的字符进行排序并比较所得数组来检查两个code值是否相同。在循环中，我们查看所有具有匹配基数的值，并查看group或function compare_basenum($b1, $b2) { $b1 = str_split($b1); sort($b1); $b2 = str_split($b2); sort($b2); return $b1 === $b2; } $newdata = array(); foreach ($data as $d) { $matching_basenums = array_filter($newdata, function ($v) use ($d) { return compare_basenum($v['basenum'], $d['basenum']); }); if (!count($matching_basenums) || !in_array($d['code'], array_column($matching_basenums, 'code')) || !in_array($d['group'], array_column($matching_basenums, 'group'))) { $newdata[] = $d; } } print_r($newdata);值是否相同，如果不同，则将该值添加到输出中。

Array ( 
    [0] => Array ( [percent] => 88.461538461538 [basenum] => 079 [code] => HL [group] => 8 )
    [1] => Array ( [percent] => 88.461538461538 [basenum] => 709 [code] => HL [group] => 0 )
    [2] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => TL [group] => 0 )
    [3] => Array ( [percent] => 88.461538461538 [basenum] => 907 [code] => HL [group] => 1 ) 
)

输出（用于基于以下OP注释的更新数据）

class EODSales
{
    public string Sales { get; set; }
    public int TC { get; set; }
    public decimal Amount { get; set; }
}

class EODBO
{
    public string Sales { get; set; }

    public List<EODSales> Values { get; set; }
}
.
.
.
.
List<EODSales> EODSalesList = new List<EODSales>();
List<EODBO> eodboList = new List<EODBO>();
.
.
.
//Inside a method - 

EODSales sales = new EODSales();
sales.Sales = "Prev";
sales.TC = 5;
sales.Amount = 500;
EODSalesList.Add(sales);
List<EODSales> localEODSalesList = new List<EODSales>();
localEODSalesList.Add(sales);

EODBO obj = new EODBO();
obj.Sales = "Baking Order";
obj.Values = localEODSalesList;
eodboList.Add(obj);


//Inside another method 

EODSales sales = new EODSales();
sales.Sales = "Prev";
sales.TC = 10;
sales.Amount = 1000;
EODSalesList.Add(sales);
List<EODSales> localEODSalesList = new List<EODSales>();
localEODSalesList.Add(sales);


EODBO obj = new EODBO();
obj.Sales = "Baking Order";
obj.Values = localEODSalesList;
eodboList.Add(obj);
