Hi all,

Is it possible to rewind a foreach loop? eg:


$numbers = array(0,1,2,3,4,5,6,7,8,9,10);

foreach ($numbers as $index => $value)
{
if ($value == 5)
{
prev($numbers);
}
echo "Value: $value" . PHP_EOL;
}

this might give you an[other] idea ... note it's
an infinite loop - watch out for those.

do {
foreach (array(0,1,2,3,4,5,6,7,8,9,10) as $k => $v) {
if ($v == 5) continue 2;
echo $v, PHP_EOL;
}
} while (true);


The above doesn't seem to work. In one of my scenarios, when I encounter and
error in a foreach loop, I need the ability to rewind the array pointer by
one. How can I achieve this?

regards,
Jeffery
