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;
}

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?

echo $numbers[$index-1] . PHP_EOL;

That will only give me the value of the previous index. What I want is to
rewind the array pointer and continue with the loop.


Of course that assumes that the value you're looking for isn't the first
element :)

I would think that if you rewound the array pointer as above, you'd simply end up in an infinite loop, as you'd keep hitting the condition that triggered the rewind. ...
