[Adrian Matarazzo]

Seguinte, estou com este erro já faz algum tempinho! Espero que me ajudem!

 

Parse error: syntax error, unexpected 'const' (T_CONST), expecting variable (T_VARIABLE) in /home/u666668492/public_html/classes/Connection.class.php on line 8

Este é a pagina que está apontando o erro, desde já obrigado!
