基于數據庫中mysql字段的Master => Detail關系：公司 - 項目 - 級別Adobe - Photoshop - 初學者Adobe - Photoshop - 高級Adobe - 插畫師 - ........Microsoft - Word - 初學者....微軟 - Excel - ....我正在努力解決多級布局，也稱為嵌套，僅在 HTML5 中沒有 JavaScript。我想使用帶有“Select field1,field2,field3”的 sql 字符串來顯示內容，就像 Windows 資源管理器樣式一樣。也許有教程/示例？到目前為止，我還沒有找到只使用 HTML 5 而不使用 JavaScript 的多級 php 腳本！

這是我關于如何在三個數組中創建條目組合的答案。
<?php
function combinations($arrays, $i = 0) {
if (!isset($arrays[$i])) {
return array();
}
if ($i == count($arrays) - 1) {
return $arrays[$i];
}
// get combinations from subsequent arrays
$tmp = combinations($arrays, $i + 1);
$result = array();
// concat each array from tmp with each element from $arrays[$i]
foreach ($arrays[$i] as $v) {
foreach ($tmp as $t) {
$result[] = is_array($t) ?
array_merge(array($v), $t) :
array($v, $t);
}
}
return $result;
}
$arrCombi=combinations(
array(
array('Microsoft','Adobe','Softskills'),
array('Word','Excel','Photoshop','Homeoffice'),
array('Grundlagen','Expert')
)
);
$line="";
foreach ($arrCombi as $k => $v){
$line .= "(".implode(" AND ",$v) . ") OR \n";
}
$line=substr($line, 0, -4);
echo nl2br($line);
echo"<hr><pre>";
print_r(
combinations(
array(
array('Microsoft','Adobe','Softskills'),
array('Word','Excel','Photoshop','Homeoffice'),
array('Grundlagen','Expert')
)
)
);
echo "</pre>";
?>
