使用来自页眉的数组

Ok so I have an array "$landing" in my header.php, then in my page.php I include the header.php but for some reason when I call the 'Name' field in the array in the page.php: echo $landing['Name']; it just doesn't work.

好了，我的标题中有一个数组“$landing”。php，然后在我的页面。php我包括标题。但是由于某种原因，当我在页面中的数组中调用“Name”字段时。php:echo $着陆(“名字”);它只是不工作。

this is how the array is being filled up, and calling it in the header works perfectly.

这就是填充数组的方式，并且在头中调用它可以很好地工作。

$landing = array();

while ($row = mysql_fetch_array($result)) {
   $str = strtolower($row['Name']);
   if ($str == $name) {
       $landing = $row;
   }
}

To clarify, $row and $landing are both arrays, and both have multiple fields 'Name' 'Color' 'Info'.

需要说明的是，$row和$landing都是数组，并且都有多个字段“Name”“Color”“Info”。

What am I doing wrong here? Do I need to make it global somehow or what's going on?

我在这里做错了什么?我需要使它全球化吗?

The original code works somehow, now as the OP said in a comment.

正如OP在评论中所说，原始代码以某种方式工作。

But my old tips still hold:

但我的老建议仍然站得住脚:

Consider using MySQLi or PDO instead of the deprecated MySQL extension!
考虑使用MySQLi或PDO，而不是废弃的MySQL扩展!
Why do you compare the dataset's column value on the client-side? You can do this on the MySQL side, it'll be faster!
为什么要比较客户端上数据集的列值?你可以在MySQL这边做，它会更快!

You are, as ComFreek correctly stated, turning $landing into a string. Instead, if you're trying to add an entry to the landing array, use [] brackets which mean "add into new entry".

正如ComFreek所正确指出的，您正在把$landing变成一个字符串。相反，如果您试图向着陆数组添加一个条目，请使用[]方括号，意思是“添加到新条目”。

$landing = array();    
while ($row = mysqli_fetch_array($result)) {
   $str = strtolower($row['Name']);
   if ($str == $name) {
       $landing[] = $row;
   }
}

I cant comment LS97 post, anyway you want to use $landing["Name"] you edit LS97 code into this:

我不能评论LS97的文章，不管怎样，你想用$landing["Name"]你把LS97的代码编辑成这个:

$landing = array();    
while ($row = mysqli_fetch_array($result)) {
   $str = strtolower($row['Name']);
   if ($str == $name) {
       $landing["name"] = $row;
   }
}

If you want to use multiple names, LS97 code is fine.

如果您希望使用多个名称，LS97代码是可以的。

The problem is what they said. (Using $landing = $row, landing will be a string.)

问题是他们说了什么。(使用$landing = $row, landing将是一个字符串。)
