If this foreach is outside of $query_item (which I presume so as your not using $this) are the properties public or otherwise accessible?David– David2010-04-09 15:35:05 +00:00Commented Apr 9, 2010 at 15:35

You should refer to $value by reference, and modify it in place:
foreach($query_item as $key => &$value)
{
$value = str_replace(' & ',' & ',$value);
}
The alternative would be to reference the item within the object using $key:
foreach($query_item as $key => $value)
{
$query_item->$key = str_replace(' & ',' & ',$value);
}
I'll also point out htmlentities(), while we're on the subject of replacing & with &.

Just for my curiosity, the only difference in your first suggestion and mjr's original is that mjr was modifying $key whilst you are modifying $value. Is that the mistake?

Modifying by Reference is smart. But the second example isn't $query_item an array? $query_item[$key] = ... ?

No. He said: "I need to remove the '&' character from each property of a php object." An object is not an array, therefore you'd need to use ->$key. However, the first one would work best. Just remove the spaces, they're unnecessary and might mess up if someone uses something like
this&that. |
foreach($query_item as $key => &$value)
{
$query_item[$key] = str_replace(' & ',' & ',$value);
}
