foreach($categories as $category)
{
print_r($category);
}
The code above gives me the following result.
stdClass Object
(
[category_Id] => 4
[category_Title] => cat 4
)
stdClass Object
(
[category_Id] => 7
[category_Title] => cat 7
)
stdClass Object
(
[category_Id] => 6
[category_Title] => cat 6
)
how can I use implode(', ' ) to get the following result:
cat 4, cat 7, cat 6
I used it, but I got an error
You can cast the object as an array.
implode(',',(array) $categories);

$categories and imploding the result does not make any sense. This answer is seemingly trying to concatenate the properties of a single object, as in implode(',', (array)$category), but that would produce '4,cat 4'.Here's an alternative solution using array_map:
$str = implode(', ', array_map(function($c) {
return $c->category_Title;
}, $categories));
$categories is already an array containing three stdClass elements which have two properties: category_Id and category_Title. He asked how to generate a new array of category titles (strings). Just casting $categories to an array wouldn't work.
Try like
foreach($categories as $category)
{
$new_arr[] = $category->category_Title;
}
$res_arr = implode(',',$new_arr);
print_r($res_arr);
