我想从 php 中的特定路径中检索这种类型的数组???如何像这个数组一样检索文件和文件夹...
children: [
{title: "Item 1", key: "node1"},
{title: "Folder 2", isFolder: true, key: "node2",
children: [
{title: "Sub-item 2.1", key: "node2.1"},
{title: "Sub-item 2.2", key: "node2.2"}
]
},
{title: "Item 3", key: "node3"}
]
我试过这个功能...
<?php
function getDirectory($path = '.', $level = 0) {
$ignore = array('cgi-bin', '.', '..');
$dh = @opendir($path);
while (false !== ( $file = readdir($dh) )) {
if (!in_array($file, $ignore)) {
if (is_dir("$path/$file")) {
echo '<li id="key1" class="folder expanded">' . $file;
echo '<ul class="folder-content">';
getDirectory("$path/$file", ($level + 1));
echo '</ul>';
echo '</li>';
}
}
}
closedir($dh);
}
?>
你可以试试这个函数：
function getDirectory($path = '.', $level = 1)
{
$result = array();
$ignore = array('nbproject', 'src', '.', '..');
$dh = @opendir($path);
$i = 0;
while($file = readdir($dh))
{
if(!in_array($file, $ignore))
{
if(is_dir($path.'/'.$file))
{
$level++;
$singleResult = array('title'=>$file, 'isFolder'=>true, 'children'=>$this->getDirectory($path.'/'.$file, $level), 'key'=>'node'.$level);
$result[] = $singleResult;
}
else
{
$result[] = array('title'=>$file, 'key'=>'node'.$level.'.'.$i);
}
}
$i++;
}
closedir($dh);
return $result;
}
我用这个函数扫描了我的一个目录，它输出：

当然，您需要自己实现将数组转换为json，只有扫描目录并为其提供适当参数的方法。
