Re: [PHP] Declaring variables from the url
Also check in php.ini register_globals to be On if you want to have vars directly available in the script...

To expand on Jay's excellent advice, you have been depending on "register globals" to set the variable names for you. This is widely regarded as a bad practice, because you don't know for sure where $var came from. You should ALWAYS use $var=$_GET['var'] when taking values from the url to set a variable. For more information on the evils of register globals, STFA. There have been many discussions in this list on that topic.

[snip] http://www.domain.com/index.php?var=1 And then, to use the variable, all I have to do is use it in the script, like so: echo "This is the value of the variable: " . $var; [/snip] echo $_GET['var']; -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
