Yes the items are grabed by their index. I'm using those arrays to manipulate 3D geometric shapes, (either vrml/x3d, OpenGL, POV and other ones**) so cartesian coordinates are first referenced in a first array, and then faces (facets?) are build giving the index of 3 (or more) points, so the index need to be the good one and not on a null or the next value. > Or will PHP realize "OK I need to change the numbers indexing the other > elements"? ** as PHP is a high level language I can write very quickly and very easily scripts to make manipulations on my 3D meshes, but the problem is that it often takes more than an hour to execute, so I realy need to learn about writing efficient code and optimizing PHP...

Perhaps there is a better way to grab the good points to build the faces, but I did not find another solution yet. If you know about another better issue to resolve this problem, please let me know about it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
