I have the following code:
$final = [1 => 2];
$id = 1;
$final[$id][0] = 3;
The code seems to work fine, but I get this warning:
Warning: Cannot use a scalar value as an array in line X (the line with: $final[$id][0] = 3).
Can anyone tell me how to fix this?
You need to set$final[$id]
to an array before adding elements to it. Intiialize it with either
$final[$id] = array();
$final[$id][0] = 3;
$final[$id]['link'] = "/".$row['permalink'];
$final[$id]['title'] = $row['title'];
or
$final[$id] = array(0 => 3);
$final[$id]['link'] = "/".$row['permalink'];
$final[$id]['title'] = $row['title'];
