Ready for review 👍

[samsonasik]

not sure about it tho...

[samsonasik]

Looking at the code, should be fine with this patch, since no 2nd argument as index, means it always array:

CodeIgniter4/system/HTTP/RequestTrait.php

Lines 266 to 277 in 4387f32

	// Return all values when $index is null
	if ($index === null) {
	$values = [];
	foreach ($this->globals[$name] as $key => $value) {
	$values[$key] = is_array($value)
	? $this->fetchGlobal($name, $key, $filter, $flags)
	: filter_var($value, $filter, $flags);
	}
	return $values;
	}
