Quote from html_entity_decode() manual:

You might wonder why trim(html_entity_decode(' ')); doesn't reduce the string to an empty string, that's because the ' ' entity is not ASCII code 32 (which is stripped by trim()) but ASCII code 160 (0xa0) in the default ISO 8859-1 characterset.

You can use str_replace() to replace the ascii character #160 to a space:

$a = html_entity_decode('>&nbsp;<');
echo 'before ' . $a . PHP_EOL;
$a = str_replace("\xA0", ' ', $a);
echo ' after ' . $a . PHP_EOL;
