how to skip elements in foreach loop

Question

I want to skip some records in a foreach loop.

For example, there are 68 records in the loop. How can I skip 20 records and start from record #21?

I'm not sure why you would be using a foreach for this goal, and without your code it's hard to say whether this is the best approach. But, assuming there is a good reason to use it, here's the smallest version I can think of off the top of my head:

$count = 0;
foreach( $someArray as $index => $value ){
    if( $count++ < 20 ){
        continue;
    }

    // rest of foreach loop goes here
}

The continue causes the foreach to skip back to the beginning and move on to the next element in the array. It's extremely useful for disregarding parts of an array which you don't want to be processed in a foreach loop.
