Read TEBESKASHI's post in the kata discussion and my reply there.

+1 for trollface

Then i suggest you try Ruby/Perl/IOCCC/GS2/J, this one is too naïve facing those beasts

Use spoiler flag next time.

@muxa92 i hate you.You makes my self-esteem lower.So i am not special && perfect?My life is a lie!

Good catch!

I know about foreach, but that wasn't my mistake.
for is actually faster than foreach, but only if I don't call count() in the condition.

So the faster solution should've been:

$count = count($buses_colors);
for ($i = 0; $i < $count; $i++) {
    ...

This way, count() only gets called once and everything runs faster.
For readability yes, foreach is better.

PS: This entire solution isn't optimized. I might have rushed through this low level kata, as a distraction on a break from work :)

I just love doing that XD ! but thanks for your comment.
