See Kristian's comments about another function that had the same behavior: http://www.progressive-comp.com/Lists/?l=php- dev&m=90592936718966&w=2 In short, it is unnecessary for functions to create or modify arbitrary global variables, and that behavior can cause unexpected side- effects. The only other place I can think of where PHP imports stuff into its symbol table is the GPC stuff. Since that happens before execution rather than in the middle of a script, it's much less likely to cause problems. Are there any other functions in PHP that create new global variables when the function is called? I don't remember seeing any, but I've barely scratched the surface of what PHP can do.
