Having a PHP file opened and selecting PHP language (Language menu, P, PHP), Notepad++ does not recognise the functions in Function List if they are like:

function getInfoTravel ($param1, &param2)
{
...
}

If we remove the space OR SPACES after the function name (getInfoTravel) it is recognised:

function getInfoTravel($param1, &param2)
{
...
}

Please, add to the regular expression that parse the PHP files the possibility to have one or more spaces after the function name.
