我在使用我的一些代码时遇到了一些麻烦......我有一个菜单布局数组：
$navigationMenu = [
SECTION_OVERVIEW => [
'hide' => TRUE,
'id' => 'overview_button',
'order' => 0,
'content/overview.php' => [
SECTION_CABINET => [
'hide' => TRUE,
'id' => 'cabinet_button',
'content/cabinet.php' => [
SECTION_AMP_PSU => [
'hide' => TRUE,
'id' => 'amps_psu_button',
'ampNoIndicator' => TRUE,
'order' => 3,
'content/amp_psu.php' => [
SECTION_AMPS_OFF => [
'hide' => false,
'id' => 'amps_off_button',
'ampNoIndicator' => TRUE,
'class' => 'red',
'order' => 4,
],
SECTION_AMPS_ALARMS => [
'id' => 'amps_alarms',
'ampNoIndicator' => TRUE,
'order' => 5,
'content/amp_alarms.php' => NULL
]
]
],
'POOP' => [
'hide' => false,
'id' => 'amps_psu_button',
'ampNoIndicator' => TRUE,
'order' => 3,
'content/amp_psu.php' => NULL
]
]
]
]
],
SECTION_SYSCONFIG => [
'id' => 'sysConfig',
'order' => 1,
'content/system_configuration.php' => NULL,
],
SECTION_SYS => [
'id' => 'system',
'order' => 2,
'content/system.php' => NULL,
],
BACK_BUTTON => [
'id' => 'backBtn',
'order' => 100,
'prev' => NULL,
],
RESCAN_BUTTON => [
'id' => 'rescan',
'order' => 101,
]
];
我有一个生成菜单的课程。

public function __construct() {
global $navigationMenu;
$menu = $navigationMenu;

private function buildMenu($menu, $depth = 0, $nestingUL = false) {
$ulNode = $this->doc->createElement('ul');
if (!$depth) {
$ulNode->setAttribute('id', 'primary-nav');
$this->rootNode = $ulNode;
}
$this->appendtoNode($menu, $depth, $nestingUL, $ulNode);
return $ulNode;
}

return;

private function hiddenArraySkipNext($arr) {

return $output;

/**

public function getMenu() {
return $this->doc->saveHTML();
}

因此，该类的目的是能够生成$ navigationMenu的嵌套或非嵌套UL（请参阅使用我通过buildMenu，appendtoNode等获得的$ nestingUL / $嵌套参数）。我还希望能够覆盖$ navigationMenu中的任何“隐藏”键（请参阅appendtoNode（）函数中的$ showElementOverride）。当阵列处于我设置的配置中时，菜单按计划显示。但是，如果我想扩展菜单，我会遇到问题。
在下面的数组配置中，我的SECTION_AMPS_OFF和SECTION_AMPS_ALARMS输出两次。
$navigationMenu = [
SECTION_OVERVIEW => [
'hide' => TRUE,
'id' => 'overview_button',
'order' => 0,
'content/overview.php' => [
SECTION_CABINET => [
'hide' => TRUE,
'id' => 'cabinet_button',
'content/cabinet.php' => [
SECTION_AMP_PSU => [
'hide' => TRUE,
'id' => 'amps_psu_button',
'ampNoIndicator' => TRUE,
'order' => 3,
'content/amp_psu.php' => [
SECTION_AMPS_OFF => [
'hide' => false,
'id' => 'amps_off_button',
'ampNoIndicator' => TRUE,
'class' => 'red',
'order' => 4,
],
SECTION_AMPS_ALARMS => [
'id' => 'amps_alarms',
'ampNoIndicator' => TRUE,
'order' => 5,
'content/amp_alarms.php' => NULL
]
]
],
'POOP' => [
'hide' => true,
'id' => 'amps_psu_button',
'ampNoIndicator' => TRUE,
'order' => 3,
'content/amp_psu.php' => NULL
]
]
]
]
],
SECTION_SYSCONFIG => [
'id' => 'sysConfig',
'order' => 1,
'content/system_configuration.php' => NULL,
],
SECTION_SYS => [
'id' => 'system',
'order' => 2,
'content/system.php' => NULL,
],
BACK_BUTTON => [
'id' => 'backBtn',
'order' => 100,
'prev' => NULL,
],
RESCAN_BUTTON => [
'id' => 'rescan',
'order' => 101,
]
];
当我将菜单配置如下时，我得到一个关于允许的内存大小耗尽的致命错误。

SECTION_OVERVIEW => [
'hide' => TRUE,
'id' => 'overview_button',
'order' => 0,

我很确定解决方案不会扩展内存限制。最终目标是能够遍历数组并吐出任何未隐藏的导航菜单按钮（嵌套或非嵌套UL），只要$ showElementOverride未设置为TRUE。如果隐藏父数组，则可以显示子项，只要它不是嵌套的UL。我还没有解决这个问题，因为我一直试图解决hiddenArraySkipNext（）函数。在过去的几天里，我一直在努力解决这个问题，所以一定要戴上一双新鲜的眼睛！
答案 0 :(得分：0)
重写了我的buildMenu（），appendtoNode（）和hiddenArraySkipNext（）函数：
