Question

我想创建一个数组，告诉我的网站页面用PHP显示的位置在$sor["site_id"]我有两个或四个字符长度的字符串。例如：23, 42, 13, 1
在我的另一个数组（调用$pages_show）中，我想将所有site_ids提供给另一个id。

$parancs="SELECT * FROM pages ORDER BY id";
$eredmeny=mysql_query($parancs) or die("Hibás SQL:".$parancs);
while($sor=mysql_fetch_array($eredmeny)) 
{
$pages[]=array(
"id"=>$sor["id"],
"name"=>$sor["name"],
"title"=>$sor["title"],
"description"=>$sor["description"],
"keywords"=>$sor["keywords"]
);
// this makes my pages array with the information about that page.

$shower = explode(", ",$sor["site_id"]);
// this is explode my site_id
$pages_show[]=array(
"id"=>$sor["id"],
"where"=>$shower
//to 'where' i want to put all the explode's elements one-by-one, to get the result like down
);

这个脚本给了我以下结果：

Array (3)
0 => Array (2)
  id => "29"
  where => Array (2)
    0 => "17"
    1 => "16"
1 => Array (2)
  id => "30"
  where => Array (1)
    0 => "17"
2 => Array (2)
  id => "31"
  where => Array (1)
    0 => "17"

但在这种情况下，我想成为这样：

Array (4)
0 => Array (2)
  id => "29"
  where => "17"
1 => Array (2)
  id => "29"
  where => "16"
2 => Array (2)
  id => "30"
  where => "17"
3 => Array (2)
  id => "31"
  where => "17"

感谢您的帮助。

Answer 1

你必须遍历$shower数组：

$shower = explode(", ",$sor["site_id"]);
// this is explode my site_id

foreach($shower as $show) {
    $pages_show[]=array("id"=>$sor["id"],"where"=>$show);
}

Answer 2

如果$ shower是数组，那么$ shower [$ i ++] nem？

制作一个两个数组
