It's also worth adding that many times, certain functions cannot be
chained elegantly or the nesting level gets out of hand, making
reusing variables a way to handle that:
$name = implode(' ', array_map(ucfirst(...), $name));
might be more readable to write as:
$name = array_map(ucfirst(...), $name);
$name = implode(' ', $name);
In this case, $name turns from an array to a string. Having to come up
with unique enough variable names just to satisfy type-checking would
be rather annoying (and it is in other languages).
