How to Find Second Largest Number in PHP

PHP has several functions that you can use to find the second largest number. These methods have the disadvantage that their time complexity is O(nlogn). Moreover, they won’t work for arrays that contain repeating elements. Instead, you need to traverse the array while keeping two indexes.

The first way is to use a foreach loop to traverse the array. This method will return the value stored in the second element, if it exists. The second method uses an if condition to check whether the value in the array is greater than the first one. The maximum value is then printed in the output.
