If not what then ??
SQLyog does not use PHP – it connects directly to the database. The SJA (SQLyog Job Agent) however can be executed from within a php script.
You must explain more in detail what your are trying to do!!
But please also read the program help file and the FAQ

If you intend to use HTTP-tunneling you also only need the PHP-tunnelling script that is included with SQLyog
