Question

我不知道是否提出了这个问题，但是我找不到答案。我有一个数组数组，我需要组合过滤器才能查看结果。从选择中，我选择了能够过滤结果的数据。我需要显示所有包含两个过滤器的结果。

<select name = "filter">
    <option value = "1"> apple </option>
    <option value = "2"> pear </option>
</select>
<Label> Combine </ label>
<select name = "filter2">
    <option value = "1"> melon </option>
    <option value = "2"> strawberry </option>
</select>

foreach ($ complete as $ subdime) {
    $ substr = $ filter;
    $ substr2 = $ filter2;
    if ($ filter! == 'total' && strpos ($ subdime [0], $ substr)! == false && $ filter2 === "") {/ * print result * /}

使用一个过滤器，一切正常。相反，如果我插入一个AND来可视化这两个对象，则向量为空。

if ($ filter! == 'total' && strpos ($ subdime [0], $ substr)! == false && strpos ($ subdime [0], $ substr2)! == false)

我的目标是能够同时打印与两个过滤器相对应的结果。

对不起，我的英语。

谢谢

        [3] => 6578931 
        [4] => null
    )

我将通过在两个过滤器中创建一个数组来解决它，并使用'in_array'检查该值像这样：

$filters = [$filter1,$filter2];
        foreach ($complete as $index => $subdime) {
            if(in_array($subdime[0],$filters)){
                // value matches one of the filters - do something
            }
        }

使用多个过滤器过滤Array of Array
