how to loop through php object and replace a string in each property ( variable )

Question

I need to remove these ' & ' characters from each property of a php object

I tried the code below but it's not working...what am I missing?

thanks dudes

foreach($query_item as $key => $value)
{
    $key = str_replace(' & ',' & ',$value);
}

Answer 1

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 &.

Answer 2

foreach($query_item as $key => &$value)
{
    $query_item[$key] = str_replace(' & ',' & ',$value);
}
