[vox-tech] php question - strict variable declarations?

[Richard S. Crawford]

Pete,

The closest thing I can think of is checking to see if the variable is set...

if (!isset($myUnsetVariable)) print "This variable isn't set, you bastard!";

I haven't played with PHP since before 4.2, so I'm not sure if new levels of functionality have been added or not, but to my knowledge there is no method in PHP of pre-declaring variables or a PHP equivalent of "use strict".

There oughtta be, though.

There are a couple of PHP lists out there run by the php.net site.  If you can wade through the tons of "How do I disable my browser's back button with PHP" or "How can I change the content of a page without having to reload it" questions, then it can sometimes even be a useful resource.  Sometimes.
