Helper::loadFromFile a procedury a triggery

V jednom velkém projektu mi několik měsíců bez jediného problému slouží toto:

<?php

/**
	 * Import taken from Adminer, slightly modified
	 * Note: This implementation is aware of delimiters used for trigger definitions (unlike Nette\Database)
	 *
	 * @author   Jakub Vrána, Jan Tvrdík, Michael Moravec
	 * @license  Apache License
	 */
	private function executeFile($file)
	{
		$query = file_get_contents($file);

		$delimiter = ';';
		$offset = 0;
		while ($query != '') {
			if (!$offset && preg_match('~^\\s*DELIMITER\\s+(.+)~i', $query, $match)) {
				$delimiter = $match[1];
				$query = substr($query, strlen($match[0]));
			} else {
				preg_match('(' . preg_quote($delimiter) . '|[\'`"]|/\\*|-- |#|$)', $query, $match, PREG_OFFSET_CAPTURE, $offset); // should always match
				$found = $match[0][0];
				$offset = $match[0][1] + strlen($found);

				if (!$found && rtrim($query) === '') {
					break;
				}

				if (!$found || $found == $delimiter) { // end of a query
					$q = substr($query, 0, $match[0][1]);

					$this->db->exec($q);

					$query = substr($query, $offset);
					$offset = 0;
				} else { // find matching quote or comment end
					while (preg_match('~' . ($found == '/*' ? '\\*/' : (preg_match('~-- |#~', $found) ? "\n" : "$found|\\\\.")) . '|$~s', $query, $match, PREG_OFFSET_CAPTURE, $offset)) { //! respect sql_mode NO_BACKSLASH_ESCAPES
						$s = $match[0][0];
						$offset = $match[0][1] + strlen($s);
						if ($s[0] !== '\\') {
							break;
						}
					}
				}
			}
		}

Kdo používáte kdyby/doctrine tak tam mám už nějakou dobu zkopírovaný ten import z admineru (vylepšený Honzou Tvrdíkem)
