In this tutorial, we will cover the following programs of PHP;

  1. Sorting an Array with Selection Sort in PHP using while loop.
  2. Sorting an Array with Selection Sort in PHP using do while loop.
  3. Selection Sort the array with form values entered by the user. (using while loop)
  4. Selection Sort the array with form values entered by the user. (using do while loop)
