我已经搜索了一段时间，但我还没有找到一个很好的解决方案。有类似的帖子用于处理1,2,3级数组，但没有一个允许未知级别的数组。
目的： 循环x级多维数组： 如果 1.值是数组，继续循环 2.不是一个关闭周期的数组 并输出为可读表格。
我可以通过嵌入foreach循环手动执行此操作，但每当我尝试构建一个递归函数时，它就会融化。
平坦的foreach示例（适用于显示的数组）。
function doit($ARR){
if( is_array($ARR) )
{
foreach($ARR as $K => $ARR2)
{
if( is_array($ARR2) )
{
$t .= '<tr><td> > '.key($ARR).'</td>';
foreach($ARR2 as $K2 => $ARR3)
{
if( is_array($ARR3) )
{
$t .= '</tr><tr><td> >> '.key($ARR2).'</td>';
foreach($ARR3 as $K3 => $ARR4)
{
if( is_array($ARR4) )
{
$t .= '</tr><tr><td> >>> '.key($ARR3).'</td>';
foreach($ARR4 as $K4 => $ARR5)
{
if( is_array($ARR5) )
{
$t .= '</tr><tr><td> >>>> '.key($ARR4).'</td>';
foreach($ARR5 as $K5 => $ARR6)
{
if( is_array($ARR6) )
{
$t .= '</tr><tr><td> >>>>> '.key($ARR5).'</td>';
foreach($ARR6 as $K6 => $ARR7)
{
if( is_array($ARR7) )
{
$t .= '</tr><tr><td> >>>>>> '.key($ARR6).'</td>';
foreach($ARR7 as $K7 => $ARR8)
{
if( is_array($ARR8) )
{
$t .= '</tr><tr><td> >>>>>>> '.key($ARR7).'</td>';
}
else
{
$t .= '<td>'.$ARR8.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR7.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR6.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR5.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR4.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR3.'</td>';
}
}
}
else
{
$t .= '<td>'.$ARR2.'</td>';

我不确定为什么你的代码会重复使用＆＃34; 25000＆＃34;同一级别的下一个条目的文本，即使它们具有不同的密钥。这是一个递归函数，您可以将其作为起点。

谢谢你，这是完美的。我几次接近这个解决方案，但一直绊倒自己。
对于其他可能发现此问题的人，这是我使用的最终解决方案。
请注意，我想要的是通过css应用缩放着色并将前导符号放在每个表头子集之前。正如malms正确地指出所有标题应该是不同的（参见来自malms的$ 25k问题）。
这就是我的结局：
function doit_recurse($cellname, $arr, $maxdepth = 0, $depth = 0, $caption ) {
$ret = "";
if ($depth === 0) {
$ret .= "<table class=\"tableData\"><caption>$caption</caption>";
}
$sym = array('', '','▶','▷','▻','▹','∙');
$close_tr = "";
$tddata = "";
$tdspan = 0;
$thclass = "";
if (!empty($cellname)) {
$thclass = "class=\"nTH$depth\"";
$tdcontent = $sym[$depth]." ".$cellname." ".$depth;
$close_tr = "</tr>";
}
foreach ($arr as $key => $value) {
if (is_numeric($value)) {
$tddata .= "<td>$value</td>";
} else {
$tdspan = $maxdepth;
$tddata .= $close_tr . doit_recurse($key, $value, $maxdepth, $depth + 1);
}
}
$ret .= "<tr><th $thclass colspan=\"$tdspan\">$tdcontent</th>$tddata";
if ($depth === 0) {
$ret .= "</tr></table>";
}
return $ret;
}
$PRN_IRS = doit_recurse('', $IRS_EX_COVERAGE, 6, 0, 'Caption name here');
正如您将看到的，我还在表格的标题中添加了。
我想要这种方法，以便我可以构建html表，并为动态选择选项构建JavaScript数组（未显示，但显而易见的是如何构建）。
为那些寻找类似内容的人实时example here。再次感谢malms，这太棒了。我真的离开了那个洞的兔子洞:)）
