这样的数组怎么创建

这样的数组 如何创建



如何把等于大分类ID的对应小分类写入 subCats
array(
id=>"$Xhref.....",
name=>"$Xtext....",
)

$dafenleishu=count($Dhref);
$xiaofenleishu=count($Xhref);

for ($x=1;$x<=$dafenleishu-1;$x++) {
$cats[]=array(
id=>"$Dhref[$x]",
name=>"$Dtext[$x]",
subCats=>array()
);

}


$Dhref //大分类ID

$Dtext //大分类名称

$Xhref //小分类ID

$XID_D //小分类对应大分类ID

$Xtext //小分类名称


输出
