+     * Wrapper function for phps preg_split
+     *
+     * This function is inspired by {@link https://github.com/thecodingmachine/safe/blob/master/generated/pcre.php}. But
+     * since this library is all about performance we decided to strip everything we don't need. Reducing the amount
+     * of files that have to be loaded, ect.
+     *
+     * @param string $pattern The pattern to search for, as a string.
+     * @param string $subject The input string.
+     * @param int $limit If specified, then only substrings up to limit are returned with the
+     *      rest of the string being placed in the last substring. A limit of -1 or 0 means "no limit".
+     * @param int $flags flags can be any combination of the following flags (combined with the | bitwise operator):
+     * *PREG_SPLIT_NO_EMPTY*
+     *      If this flag is set, only non-empty pieces will be returned by preg_split().
+     * *PREG_SPLIT_DELIM_CAPTURE*
+     *      If this flag is set, parenthesized expression in the delimiter pattern will be captured
+     *      and returned as well.
+     * *PREG_SPLIT_OFFSET_CAPTURE*
+     *      If this flag is set, for every occurring match the appendant string offset will also be returned.
+     *      Note that this changes the return value in an array where every element is an array consisting of the
+     *      matched string at offset 0 and its string offset into subject at offset 1.
+     *
+     * @return string[] Returns an array containing substrings of subject
+     *                                                      split along boundaries matched by pattern
