+            and we can create a constant valued array of desired length using the following function:
+            array_fill((int: start index),(int: number of elements),(value to be put));
+
+            example:
+            <?php
+            $a = array_fill(5, 2, "bosecodes" );
+            print_r($a);
+            ?>
+
+            the output of above code will be:
+            Array
+            (
+           [5]  => "bosecodes"
+           [6]  => "bosecodes"
