访问数组元素时出错。
这是我当前的代码：
第一种方法：：
var_dump($parent_array->info->gcatname);
错误（第一种方法）：
<b>Notice</b>: Trying to get property of non-object
第二种方法：：
print_r($parent_array[0]['info']['gcatname']);
错误（第二种方法）：：
<b>Fatal error</b>: Cannot use object of type stdClass as array
阵列如下：
array(1) {
[0]=>
array(2) {
["is_parent"]=>
bool(true)
["info"]=>
object(stdClass)#6 (5) {
["id"]=>
string(1) "1"
["gcatname"]=>
string(9) "Swine Flu"
["gcatowner"]=>
string(13) "Vaccine India"
["gcatactive"]=>
string(1) "1"
["gcatadded"]=>
string(19) "2016-05-01 08:30:36"
}
}
}
简单地说：$parent_array[0]['info']->gcatname
array(1) {
[0]=> // array(2) stands for the fact that this element with index 0 is an array with the size '2' and it can only be accesses using []
array(2) {
["is_parent"]=>
bool(true)
["info"]=>// object(stdClass) stands for the fact that this element with index 'info' is an array with the size '5' and it can be accesses using ['info']
object(stdClass)#6 (5) {// here you have accessed the object now when you wish to access inside this scope you need to use this ->
["id"]=>
string(1) "1"
["gcatname"]=>//by using ->gcatname you access the property gcatname of the object
string(9) "Swine Flu"
["gcatowner"]=>
string(13) "Vaccine India"
["gcatactive"]=>
string(1) "1"
["gcatadded"]=>
string(19) "2016-05-01 08:30:36"
}
}
}
