- This program is used to find the Second Biggest number from the given N numbers using PHP.
- Each element is compared with the next element, If the element is greater than the other in comparison then the elements can be swapped.
- After doing this for each element of the given array, then we get the Output.

else if ( $arr[$i] > $second && $arr[$i] != $first )
