Code Explanation for For Loop In PHP

  1. Here for ($x = 0; $x <= 20; $x++) specifies $x = 1, which means the expression, ($x<= 20), is true. Therefore, the echo statement is executed, and $x gets incremented by 1 and becomes 2.$x = 2, which means the expression, ($x <= 20), is true. Therefore, the print statement is executed till the value hits 20, and $x gets incremented by 2 and becomes 3.
