[RESOLVED] setting current array elements

sssphp

How do I set the current array element to a particular key? For example, in:

$array (
0 => "zero",
1 => "one",
2 => "two"
)

I've performed this action:

$mykey = array_search('one', $array); // $mykey now = 1

I want to set the current element to $mykey so that I can use:

prev($array); // or next($array);

to call the previous or next array value.

(If there's a simpler way of doing the whole thing than starting with array_search(), I'm open to that too.)

Try this:

$array = array(0 => "zero", 1 => "one", 2 => "two");
reset($array);
while (current($array) !== 'one') {
    if (!next($array)) {
        echo 'Not found';
        break;
    }
}
// Now the pointer will be at the first occurance of value "one".

Thanks, that's perfect.

Glad to help, but it's not as perfect as I had hoped. I made a mistake with the "if" clause. It should be:

if (next($array) === false)

The other way it will fail if it comes across a value that evaluates as false, like 0 or ''.
