大纲
花了两天的时间试图让它发挥作用......
解决方案
我想将我的数组重组为具有以下结构的多维数组：
Level 1 -> All level 1s
Level 2 -> All level 2s
Level 3 -> Each level Three Item
Level 3 -> Each level Three Item
Level 2 -> All level 2s
Level 3 -> Each level Three Item
Level 3 -> Each level Three Item
Level 1 -> All level 1s
Level 2 -> All level 2s
Level 3 -> Each level Three Item
Level 3 -> Each level Three Item
Level 2 -> All level 2s
Level 3 -> Each level Three Item
Level 3 -> Each level Three Item
数据
数据按我需要的顺序编写。例如，level 2正下方的所有Level 1都应位于其父Level 1内，直到数据中出现下一个Level 1为止。对于Level 2和3，这应该相同。基本上直到更高的数字出现，它应该开始一个新的行。
我有许多不同的值，下面的数据只是一个例子。数组level内部指的是它应该位于哪个级别。

您可以尝试使用PHP链接operator &，尝试这样的事情：
$collection = array();
$list = yourArray[];
foreach ($list as $item) {
if (isset($list[$item['key']])) {
$list[$item['key']]['levels'][$item['key']] =& $list[$item['key']];
} else {
$collection[$item['key']] =& $list[$item['key']];
}
}
第二个变种
$row = array();
if (is_array($source) && !empty($source)) {
foreach ($source as $item) {
if (!isset($row[$item['level']])) {
$row[$item['level']] = array($item['level']);
$row[$item['level']]['parent'] = $item['level'] - 1;
}
if(isset($row[$item['level']])){
$row[$item['level']]['child'][$item['key']] = $item;
}
}
if(!empty($row)){
foreach($row as $rowK => $rowV){
if(isset($row[$rowV['parent']])){
$row[$rowV['parent']]['level-' . $rowK][] =& $row[$rowK];
} else {
$collection[$rowK] =& $row[$rowK];
}
}
}
}

这就是我想出来的......这不是一种非常有效的方法，但也许有人可以把它变成一个花哨的递归函数来使它抽象化 - 我尝试了一点，但我真的很喜欢递归： - p
function cascade_array ($array, $current_level = 1) {
// filter only the array elements with the level==current_level
$chunks = array_filter ($array, function ($v) use ($current_level) {
return $v['level'] == 1; }
);
// extract the keys from those elements an put them in reverse order
$splice_keys = array_reverse(array_keys($chunks));
// now splice the array at those keys and put the
// array-parts in a result-array, so you have an array of e.g. all level1
foreach ($splice_keys as $offset) {
$results[] = array_splice($array, $offset);
}
//now walk through the results and basically do the same
foreach($results as &$level) {
$level[0]['children'] = array();
$array = array_splice($level, 1);
$chunks = array_filter ($array, function ($v) use ($current_level) {
return $v['level'] == 2; }
);
$splice_keys = array_reverse(array_keys($chunks));
foreach($splice_keys as $offset) {
$level[0]['children'][] = array_splice($array, $offset);
}
foreach($level[0]['children'] as &$child_level) {
$child_level[0]['children'] = array();
$array = array_splice($child_level, 1);
$chunks = array_filter ($array, function ($v) use ($current_level) {
return $v['level'] == 3; }
);
$splice_keys = array_reverse(array_keys($chunks));
foreach($splice_keys as $offset) {
$child_level[0]['children'][] = array_splice($array, $offset);
}
}
}
return $results;
}
我猜这段代码实际上非常简单。这是一个有效的例子：http://codepad.viper-7.com/kb5JBc - 我希望它有所帮助：）

递归实体从来都不容易，特别是如果你开始使用PHP。
以下是一个简短的函数，它通过使用php引用来避免使用递归函数的需要。引用可能会令人困惑，递归也是如此。最好的建议是阅读并尝试一些事情，以便弄清楚他们的行为方式。
以下工作使用堆栈跟踪级别，并继续引用最后一级以查找最新的父级。
function stackItems( $items ){
$level = 0;
$return = array();
$stack = array(&$return);
foreach ( $items as $key => $item ) {
while ( $level >= $item['level'] ) {
unset($stack[$level--]);
}
$parent = &$stack[$level];
if ( !isset($parent['children']) ) {
$parent['children'] = array();
}
$parent['children'][] = &$items[$key];
if ( $item['level'] > $level ) {
$level = $item['level'];
$stack[$level] = &$items[$key];
}
}
return $return['children'];
}
评论版：
function stackItems( $items ){
$level = 0;
$return = array();
/// build our stack with our return array as first item
$stack = array(&$return);
/// step each item
foreach ( $items as $key => $item ) {
/// if our next item is lower down than current
/// level, drop the stack down.
while ( $level >= $item['level'] ) {
/// we may as well unset to clear memory
unset($stack[$level--]);
}
/// create a shortcut reference to our parent on the stack
$parent = &$stack[$level];
/// to avoid warnings create the children array first
if ( !isset($parent['children']) ) {
$parent['children'] = array();
}
/// now add ourselves to the current parent on the stack
$parent['children'][] = &$items[$key];
/// if our current item is higher level than current, add to
/// the stack ready to be treated as the next parent.
if ( $item['level'] > $level ) {
/// level ourselves to the current item
$level = $item['level'];
/// store in the stack a reference to item
$stack[$level] = &$items[$key];
}
}
/// return the first set of children as there seems
/// to be only one level 1 item.
return $return['children'];
}
