Bug #16637: Environnement variables collision

From: R.Hermann@ulg.ac.be Operating system: Linux PHP version: 4.1.2 PHP Bug Type: *General Issues Bug description: Environnement variables collision Hello, After updating to MDK 8.2 - PHP 4.1.2. I encoutered serious troubles with my php website. I managed to solve it and relate it to an environnemental variable problem. This script : <? echo $out."<BR>"; $c=1; $out[$c]=153.2; echo $out[$c]."<BR>"; $den[$c]=153.2; echo $den[$c]."<BR>"; phpinfo(); ?> Gives the following output : /dev/vc/ 1 153.2 This may be a problem, since a lot of new variables have been defined which have lower case names and are quite common ( examples : $out,$res, ...). Furthermore, the content of an array having the same name as predefined variables seems to be seriously affected. We found that defining the array with $out=array(); helps fixing the problem. I thought you might be interested.
