从数组中获取一个项目

I have this array $node->taxonomy which puts out these data, if I var_dump() it:

array(1) {
 [4]=>  object(stdClass)#21 (5) {
   ["tid"]=>  string(1) "4"
   ["vid"]=>  string(1) "4"
   ["name"]=>  string(9) "Marketing"
   ["description"]=>  string(0) ""
   ["weight"]=>  string(1) "1"
 }
}

how can I extract the element "name" from it?

This way:

$node->taxonomy[4]->name

$node->taxonomy[4]->name

As simple as:

$node->taxonomy[4]->name

<?php
echo $node->taxonomy[4]->name;

or if you don't know the number (or the number changes) but its the first element in the array you could use:

<?php
$x = current($node->taxonomy);
echo $x->name;
