在PHP中从数组中获取值

I'm trying to get the value out of an array in PHP.

我试图从PHP中的数组中获取值。

The value of $v when displayed with print_r($v) is as follows:

使用print_r（$ v）显示的$ v值如下：

Array ( [0] => Array ([name] => BLARGH ) 
        [1] => Array ( [name] => TEMP CATEGORY ) 
       )

I'm trying to iterate over this and pull out the value of the name key as follows:

我正在尝试迭代这个并提取名称键的值，如下所示：

foreach($v as $category) {
 echo  $category->name; 
}

The echo returns no value. Further, if I add a print_r($category) to the loop I get a return of

echo不返回任何值。此外，如果我在循环中添加print_r（$ category），我会得到一个返回

Array ( [name] => TEMP CATEGORY )

How do I get the name value out of the array?

如何从数组中获取名称值？

5 个解决方案

#1

inside your foreach loop do $category['name']

在你的foreach循环中做$ category ['name']

#2

This is an array, not an object. Use array notation:

这是一个数组，而不是一个对象。使用数组表示法：

echo $category['name'];

See here: http://3v4l.org/gPL27

见这里：http：//3v4l.org/gPL27

#3

foreach($v as $category) {
   echo  $category['name']; 
}

#4

foreach($v as $category) {

   echo  $category['name']; 

}

what you did wrong:

你做错了什么：

in this case:

在这种情况下：

$catagory->name

$category would need to be an object, not an array

$ category需要是一个对象，而不是一个数组
