PHP implementation bubbling algorithm

I found a lot of companies in the interview will be a bubble algorithm of the problem, so the basic algorithm, the general programmer should be written out, but today I looked at the internet, found a lot of articles in the bubbling algorithm is wrong, is not bubbling algorithm! Also openly say what analytic bubble algorithm, is really misleading new AH. I just went directly to the code, which is the bubbling algorithm.

 
 $ary [$j + 1]) {$tmp = $ary [$j]; $ary [$j] = $ary [$j + 1]; $ary [$j + 1] = $tmp;}}} return $ary;} $ary = [1,6,789,3,56,8,1234,45]; $newAry = Bubblesort ($ary);p rint_r ($newAry);? >
