How to reverse an array in php WITHOUT using the array reverse method
Below is the code to reverse an array, The goal here is to provide with an optimal solution. Compared to the approved solution above, my solution only iterates for half a length times. though it is O(n) times. It can make a solution little faster when dealing with huge arrays.
<?php $ar = [34, 54, 92, 453]; $len=count($ar); for($i=0;$i<$len/2;$i++){ $temp = $ar[$i]; $ar[$i] = $ar[$len-$i-1]; $ar[$len-$i-1] = $temp; } print_r($ar)?>
