如何在第x个元素后停止递减迭代？

So I have a for loop that is decreasing...

for ($i=count($array); i>0; $i--;)
{
 if(condition)
 {DO SOMETHING like print the element in a decreasing manner}
 if(enter ending iteration condition here after xth element) break;
}

that pretty much sums up my question. How do I formulate the ending iteration - let's say after 5 elements printed I want to stop the iteration.

$j = 0;
for ($i=count($array); $i>0; $i--)
{
    if(condition)
    {
        DO SOMETHING like print the element in a decreasing manner;
        $j++;
    }
    if($j > 4){
        break;
    }
}

Try to reverse the count of the loop. Instead of decreasing, try to increase so you will have a count of how many items are being printed.

<?php
for ($i = 0; $i < count($array); $i++)
{
    if(condition)
    {
        /* DO SOMETHING like print the element in a decreasing manner */
    }

    /* replace (nth) with the needed number */
    if($i === (nth)) break;
}

You could set the limit based on the count, like:

$loop_limit = 5;
$array_count = count($array);
$last = $array_count - $loop_limit;

for ($i = $array_count; $i >= $last ; --$i) {
    if ( $i == $last ) {
            //Do whatever you need at this point
    }
    //do the normal loop action
}
