模型代码：
public static
function get_list1()
{
$list = self::where('pid', 0)->select();
foreach ($list as $value) {
$son = self::where('pid', $value['tid'])->select();
if (count($son)) {
foreach ($son as $value1) {
$sun = self::where('pid', $value1['tid'])->select();
if (count($sun)) {
foreach ($sun as $value2) {
$con = self::where('pid', $value2['tid'])->select();
if (count($con)) {
foreach ($con as $value3) {
$con2 = self::where('pid', $value3['tid'])->select();
if ($con2) {
foreach ($con2 as $value4) {
$con3 = self::where('pid', $value4['tid'])->select();
if ($con3) {
$value4['level'] = 5;
$value4['children'] = $con3;
}
}
$value3['level'] = 4;
$value3['children'] = $con2;
}
}
$value2['level'] = 3;
$value2['children'] = $con;
}
}
$value1['level'] = 2;
$value1['children'] = $sun;
}
}
$value['level'] = 1;
$value['children'] = $son;
}
}
return json(['code' => 0, 'data' => $list]);
// print_r($list);
} 最佳答案
