Bug description: str_replace('foo', some_func(), $text) ALWAYS call some_func()
Description:
------------
In str_replace(), if you put as a replace string a call to a function
(that returns a string), this call is executed always, even if the text to
be replaced is not found in the text.
Reproduce code:
---------------
function some_func()
{
echo "some_func() was called!\n";
return 'bar';
}
echo str_replace('foo', some_func(), "aaaaa");
Expected result:
----------------
aaaa
Actual result:
--------------
some_func() was called!
aaaa
