I've got a problem which I can't seem to find a solution to. In a foreach loop
foreach( $results->result as $item )
the following code
$item->title = str_replace( " - Home", "", $item->title );
always throws an error
Catchable fatal error: Object of class stdClass could not be converted to string
I thought str_replace was able to handle arrays? What would I need to change in order to get this working?
Thanks for any advice!
It's not an array, it's an object, as the error says... did you get it with json_decode() by any chance?
However, the solution is simple - cast it to an array:
$item->title = str_replace( " - Home", "", (array) $item->title );
Another point about this is that if you are wanting to modify the data held in $results->result, and not just a copy of it, you will need your foreach to be:
foreach( $results->result as &$item )
...and get item as a reference, not a copy...
$item->title seems to be an object of type stdClass, and not a string. Do var_dump($item->title) to see what the object looks like.
Also, you loop won't do what you expect, after the loop has finished, all objects in $results->result will still have the same values (use foreach($results->result as &$item) (pass by reference))
Do a var_dump on $item->title, because it isn't an array, it is an object. str_replace can only handle actual arrays and strings. If you're expecting this to be an array, then you might have some problems elsewhere and I would look into that.
If you're just looking for a patch, you might be able to get away with casting it. If everything else is working, I would do this because it really has the fewest side-effects:
// convert it to an array before passing it through str_replace
// (array) $item->title
// then convert it back to its original form by casting the result back
// (object) str_replace
$item->title = (object) str_replace( " - Home", "", (array) $item->title );
If title has to be an array, you can get away without the (object), but I think it would be a better idea to track down where title is being set and have the value correct to begin with.
BTW — if you're planning on using $item->title outside of the loop, you also need to make sure you are using a reference so that the item itself is updated:
foreach($results->result as &$item)
{
$item->title = (object) str_replace( " - Home", "", (array) $item->title );
}
$item->titleis an object.
