And while loops are just gotos in disguise. Pretty much anyway.

However, the for() loop has a couple of points in favour over the while loop:

• It doesn't "leak" loop-variables. The scope of the $index/$i variable is limited to the loop, unlike the while, where the scope of $index extends to the surrounding block.
• All statements needed for the loop control - initialization of the variant, the condition, and the increment of the variant are all together. On one line even. At the while, the initialization of the variant is outside the while, then we have the condition, and somewhere in the block, we have the increment of the variant.

Reason enough for me to pick a for loop over a while in this case.
