PHP多维数组增量复制

Question

我有一个包含产品的数组，在其中我想搜索重复的名称并增加重复的值。

我尝试创建一个空数组，并将所有的标题值键推到它，然后我发现了array_count_values中每个键值有多少重复项。

这是我的阵列；

$products=Array
(
    [0] => Array
        (
            [0] => 'Intel I3',
            [1] => 146,
            [2] => 'intel-i3'
        ),

    [1] => Array
        (
            [0] => 'Intel I3',
            [1] => 146,
            [2] => 'intel-i3'
        ),
    [2] => Array
        (
            [0] => 'Intel I3',
            [1] => 250,
            [2] => 'intel-i3'
        ),
    [3] => Array
        (
            [0] => 'AMD graphic',
            [1] => 146,
            [2] => 'amd-graphic'
        )
);

我希望这个结果增加1。

我怎样才能得到这个结果？

$products=Array
(
    [0] => Array
        (
            [0] => 'Intel I3',
            [1] => 146,
            [2] => 'intel-i3'
        ),

    [1] => Array
        (
            [0] => 'Intel I3_1',
            [1] => 146,
            [2] => 'intel-i3'
        ),
    [2] => Array
        (
            [0] => 'Intel I3_2',
            [1] => 250,
            [2] => 'intel-i3'
        ),
    [3] => Array
        (
            [0] => 'AMD graphic',
            [1] => 146,
            [2] => 'amd-graphic'
        )
);

Answer 1

$titleCounts = array();

foreach ($products as &$product) {

    if (!isset($titleCounts[$product[0]])) {
        $titleCounts[$product[0]] = 0;
    } else {
        $titleCounts[$product[0]]++;
        $product[0] = ($product[0].'_'.$titleCounts[$product[0]]);
    }
}

Answer 2

<?php
$counter = [];
$i = 0;
foreach($products as $product){
    $counter[] = $product[2];
    $vals = array_count_values($counter);
    $current_number = $vals[$product[2]];
    if($current_number)
        $products[$i][0] .= '_'.$current_number;
    $i++;
}

那应该行。

测试过了它就能用了。

$tmpArray = array();

foreach ($products as &$product) {
    $name = $product[0];
    if (array_key_exists($name, $tmpArray)) {
        $product[0] = $name . '_' . $tmpArray[$name];
        $tmpArray[$name]++;
    } else {
        $tmpArray[$name] = 1;
    }
}
unset($product);
