adding variable numbers in PHP loop counter -


i've got php loop , counter called $total set 0 before loop. once loop starts adding value of $weight loop counter. did this:

$total=0; foreach ($weights $weight){     $total = $total+$weight; }

but realised works this:

$total=0; foreach ($weights $weight){     $total += $weight; }

question correct method or if both correct better method?

thanks

both correct, , neither better, strictly speaking. they function identically.

that said, coding styles prefer += because it's easier read, while others prefer $x = $x + $y because requires more deliberate action write, makes more obvious happening, , reduces likelihood of single-character typo.
