Answer 1

PHP < 5.3:

preg_replace_callback('/\s*\d+\s*/', create_function('$a', 'return trim($a[0]) > 5000? " " : $a[0];'), $input);

PHP >= 5.3 (closure support):

preg_replace_callback('/\s*\d+\s*/', function ($a) {
    return trim($a[0]) > 5000? " " : $a[0];
}, $input);

Answer 2

preg_replace('/\b0+((?!5000)[5-9]\d{3}|[1-9]\d{4,})(\.\d+)?/', '', $string);
