Accessing html parameter in PHP |

I'm trying to do a simple test php script for sessions. Basically it increments a counter (stored in $_SESSION) every time you refresh that page. That works, but I'm trying to have a link to destroy the session which reloads the page with the ?destroy=1 parameter. I've tried a couple of if statements to see if that par... |

Heavy emphasis on simple. I've never made an installer and I'd rather not have to learn much. A system that I could hand a pile of files to and it would make some smart guesses about where to put them would be ideal.

First of all, [here's a great article with tips on unit testing][1]. Secondly, I found a great way to avoid making tons of changes in old code is to just refactor it a little until you can test it. One easy way to do this is to make private members protected, and then override the protected field.

I don't believe SQL Server has a built-in split function, so other than a UDF, the only other answer I know is to hijack the PARSENAME function:

Which language are using? It seems like pretty much all of them have built-in SQL escape functions that would be better to use.
For example, PHP has [mysql_real_escape_string](http://us2.php.net/manual/en/function.mysql-real-escape-string.php) and [addslashes](http://us2.php.net/manual/en/function.addslashes.php). |

No, unfortunately, and if you think about it, that information would be worthless anyway since the file could become locked the very next second (read: short timespan).
Why specifically do you need to know if the file is locked anyway? Knowing that might give us some other way of giving you good advice. |
