两个while循环在一个页面中

Question

can I have two while loops with same condition but different if statements in one page?

For instance:

$qtytoAdd = $rec_qty[$mat_key];

while($qtytoAdd > 0){
    if(($remBalance - $qtytoAdd) >= 0) {
    //do something
    $qtytoAdd = 0
    }else{
    //do something
    $qtytoAdd = $qtytoAdd - $remBalance
    }
}

And something like this:

while($qtytoAdd > 0){
    if(($reqRemBal- $qtytoAdd) >= 0) {
    //do something
    $qtytoAdd = 0
    }else{
    //do something
    $qtytoAdd = $qtytoAdd - $reqRemBal
    }
}

The $qtytoAdd variable is actually defined at beginning before the loops. What I'm trying to do is run both while loops at the same time with both $qtytoAdd of each while loops having the same values at first.

Answer 1

Sure but if you have them one after each then to break the first one, you would either need to force a break or make $qtytoAdd != 0

If it is the latter than it would cause the second loop to not be executed.

If you explain what you are trying to do, there should be a more elegant way to do it.

I think what you are actually looking for is just this:

$qtytoAdd = $rec_qty[$mat_key];

while($qtytoAdd > 0){
    if(($remBalance - $qtytoAdd) >= 0) {
    //do something
    $qtytoAdd = 0
    }else{
    //do something
    $qtytoAdd = $qtytoAdd - $remBalance
    }
    //second block
    if(($reqRemBal- $qtytoAdd) >= 0) {
    //do something
    $qtytoAdd = 0
    }else{
    //do something
    $qtytoAdd = $qtytoAdd - $reqRemBal
    }
}
