这样的数组如何创建-PHP Tutorial-php.cn

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
