Re: [PHP] Rewind foreach loop

I think the best option for me is to refactorise my code a bit to cater to my
situation. Thanks all for your help.

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.

and you're going to be in an endless loop then.. because each time it
gets rewound, it gets the same key again and rewinds and ...

No, I am only rewinding if there is an error. Then I have the script
auto-learning from the error, fix a config file and then want to go back to
the array pointer to re-execute the process.

You could do it with a for or while loop probably.

Thats what I am looking at now.

What are you trying to achieve? Maybe there's an alternative.

As mentioned above.

cheers,
Jeffery

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. ...
