URL Question

stephen

This may be a stupid question but I am wondering how this works. When I see a URL that has (page).php3?(variable)=(value) ex:list.php3?num=1

I have also seen the same format with asp and cfm. I assume that ASP and coldfusion works the same way as PHP does.

Can anybody explain what this is doing. Is the site using the same page everytime but just changing a section according to the value?

thanks

Yes, basically...when you call a url such as list.php?num=1, then a variable $num is created with a value of 1. You can then use this variable for whatever you want. Often it's used to refer to a row in a database, for example. You issue a query and get the row where some id is equal to $num. Then display the data from that row. The same script, or php file, can be used for every row in the database, just by passing another num to it.

Hope that helps...

You should really start a new thread for this question, it's not related to the original question.

PHP isn't compiled. You just call up the page in your web browser and as long as your server is set up correctly to parse PHP pages, then it will work...
