PHP - How deep should I break out of the loops? - php

Question

I have infinite loop in PHP and need to know the integer after the break in the switch case. Right now I use break 5; but I am now sure if this is right. Could someone tells me how to break out of all of the loops but while (true). I removed the unnecessary code so only the loops are left.
$i = 0;
while (true)
{
// After the break 5 in the switch we should land here again
foreach ($users as $user)
{
while ($i < 10)
{
if (!empty($user))
{
if (isset($user->id))
{
switch($user->id)
{
case 1:
break 5;
default:
break 5; // Need to break out the foreach. So a break five right?
}
}
}
$i++;
}
}
$i=0;
}

The answer is 3, as break ends execution of the current for, foreach, while, do-while or switch structure.
Where break 1 only exists the switch, 2 the while and 3 the foreach and 4 the main while.
But perhaps this is a better method, as you specifically state where to go instead of guessing. You cannot place the goto marker inside a loop, but in your case you can just make it before the loop.
$i = 0;
mybegin:
while (true){
# 1. After the break 3 in the switch we will -not- land here.
# 3. So if you want to start here, you will need to use the goto statement.
foreach ($users as $user){
while ($i < 10){
if (!empty($user)){
if (isset($user->id)){
switch($user->id){
case 1:
break 3;
default:
goto mybegin;
}
}
}
$i++;
}
}
# 2. Using break 3, the code continues here.
$i=0;
}
But I have to say that I never needed that many loops or a goto statement for that matter as there is always a better way.
