Re: Rewind foreach loop

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? regards, Jeffery

No, you can't rewind the array. Foreach makes a copy of the array, and works off that copy. You might need to look into using do...while() instead Something thing like this should work. <?php $row = current($your_array); Gives you the first element in $your_array do { ... work with your $row... determine if their is an error ... if ( $error ) { # Watch out for infinite loop.... # maybe have a counter that increments each time it rewinds $your_array

		#    and have it stop at 10 loops or something.

prev($your_array); } } while( $row = next($your_array) ); ?> This way, you are working on the only copy of $your_array -- Jim Lucas "Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them." Twelfth Night, Act II, Scene V by William Shakespeare
