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       $cats[]=array(
id=>"$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
