I am having to do:
$sourceElement['description'] = htmlspecialchars_decode($sourceElement['description']);
I want to avoid that redundant mention of the variable name. I tried:
htmlspecialchars_decode(&$sourceElement['description']);
and
call_user_func('htmlspecialchars_decode', &$sourceElement['description']);
That did not work. Is this possible in PHP? Call a function on a variable?
It depends on function.
htmlspecialchars_decode()returns the result, it doesn’t modify the original variable. And you can do nothing about it.
