我有这一阵列:$node->taxonomy,其中载列这些数据,如果是“Ivar_dump():

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"
 }
}

我如何从中提取“姓名”要素?

问题回答

这样:

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

或者如果你不知道数字(或数字变化),那么你可以使用的阵列中的第一个要素是:

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

简单明了:

$node->taxonomy[4]->name
