Dechiphering the Adoptables Script

[Ansem717]

I'm in my learning stages of PHP. I've done a few variable manipulations and within the Adoptables Script, I've been able to add a link to the ACP within the menu bar. Hey, I think it's pretty cool that I can figure out where things are, k?

Thing is, I always am stumped upon this code:

PHP Code:

$i = 0
while ($i < 1) {

execute certain codes

$i++
} 


The above confuses me... Why would you execute codes within a while loop if you're only going to do it once? Why don't you just erase the $i variable completely? I physically see no purpose within that while statement. Can someone define this for me?
