我的数组有问题，已经在这里搜索过了。

这是数组：

我试过这段代码：

$cod = '';
$data = '';
$prazo = '';
$titulos=array('cod','tipo1','tipo2');
for ($i = 0; $i < count($parcelas); $i++) {
    for ($col = 0; $col < count($parcelas[$i]['values']); $col++) {
        foreach ($parcelas[0]['values'][$col] as $item){
            $cod = $item;
            echo $cod . '<br>';  
            if (!in_array($parcelas[$i]['column_title'], $titulos)) {
                for ($col = 0; $col < count($parcelas[$i]['values']); $col++) {
                    foreach ($parcelas[$i]['values'][$col] as $item){
                        if ($item != 0) {
                            $prazo = substr($parcelas[$i]['column_title'],1);
                            echo 'codigo '. $cod . ' dados = '. $item . ' prazo ' . $prazo . '<br>';
                        }
                    }
                }
            }                 
        }
    }

我需要什么：分别存储数组的每个数据，但同时插入月数（prazo）和第二个数组之外的 cod，我可以使用我的代码分隔数据，但代码始终是第一个……

cod 在第一个数组中，是唯一值

另一个数组名称是我想忽略的一些列

我需要获取列中除列code之外的每一个值，而且每一个值都必须和他所在行的cod值相关

有什么提示吗？

【问题讨论】：

codigo 是唯一的吗？所以不会有超过 1 个codigo = cod?
foreach ($parcelas[0] 应该是foreach ($parcelas[$i] 我认为
但是所有这些循环肯定是错误的
codigo 是标题列的名称 $parcelas[0] 是为了获取我必须与数据一起包含的代码，这是数据的 ID
我在第一篇文章中做了一些更改以更清晰

也许你正在寻找的东西：

function getMaxValues(array $array): int
{
    $max = 0;
    foreach ($array as $data) {
        if (count($data['values']) > $max) {
            $max = count($data['values']);
        }
    }
    return $max;
}

function mergeColumns(array $array): array
{
    $max = getMaxValues($array);
    $result = [];
    for ($i = 0; $i < $max; $i++) {
        $subResult = [];
        foreach ($array as $data) {
            if (isset($data['values'][$i])) {
                $subResult[$data['column_title']] = $data['values'][$i];
            } else {
                $subResult[$data['column_title']] = null;

$array = mergeColumns($array);

var_dump($array);

太棒了！有效！非常感谢你是个天才！祝你有美好的一天！

【解决方案2】：

如果column_title 是唯一的，那么您可以对其进行索引并提取values。然后你可以从那里提取valor 值：

foreach(array_column($parcelas, 'values', 'column_title') as $condigo => $values) {
    foreach(array_column($values, 'valor') as $value) {
        echo "$condigo $value";
    }
}

很难理解你对 vars、output、in_array 等所做的其他事情，但只需使用这种方法并适应。

【讨论】：

codigo 不是唯一的，code 是列名，一个标题，唯一的是数组第一项的值，本例中是 cod
我在第一篇文章中做了一些更改以更清晰
这就是我的意思，codigo 列 "cod" 等中的 "value" 是独一无二的。试试它应该可以正常工作的代码。
对不起，我不明白第二个代码，我需要在 array_map 函数中插入其他内容吗？
不，这会将数组的数组压缩成一个维度。或者只使用第一个。
