Split below array and get values like
Category
Brand
Subcategory
Packaging
Packing
Array
(
[0] => Array
(
[0] => stdClass Object
(
[col_ref_name] => Category
)
)
[1] => Array
(
[0] => stdClass Object
(
[col_ref_name] => Brand
)
)
[2] => Array
(
[0] => stdClass Object
(
[col_ref_name] => Subcategory
)
)
[3] => Array
(
[0] => stdClass Object
(
[col_ref_name] => Packaging
)
)
[4] => Array
(
[0] => stdClass Object
(
[col_ref_name] => Packing
)
)
)
use a code like below :
foreach($yourArray as $array)
{
echo $array[0]-> col_ref_name . "<br>";
}
Your array has objects in the sub array and col_ref_name is the property of that objects, so i used a foreach loop to go through all elements of the array (which are objects) and then access the data in the col_ref_name.
I hope this will help.
