"unset" is what you are looking for.
Code:
unset arr[3]

My code sample follows:

Code:
#!/bin/bash

example[1]="one"
example[2]="two"
example[3]="three"
example[4]="four"
example[5]="five"

echo "A simple list, iterate over it to show elements"

for i in "${example[@]}"; do
        echo $i;
done;

echo "Unsetting 3rd element of array with: unset example[3]"
unset example[3]

echo
echo "Iterate over the modified list."

for i in "${example[@]}"; do
        echo $i;
done;

And then I tested it

Code:
-bash-3.00$ ./test.sh
A simple list, iterate over it to show elements
one
two
three
four
five
Unsetting 3rd element of array with: unset example[3]

Iterate over the modified list.
one
two
four
five

ARRAY_SHIFT(3)								 1							    ARRAY_SHIFT(3)

array_shift - Shift an element off the beginning of array

SYNOPSIS

       mixed array_shift (array  &$array)

DESCRIPTION

       array_shift(3)  shifts  the  first value of the $array off and returns it, shortening the $array by one element and moving everything down.
       All numerical array keys will be modified to start counting from zero while literal keys won't be touched.

       Note

	      This function will reset(3) the array pointer of the input array after use.

PARAMETERS

	      o $array
		- The input array.

RETURN VALUES

	Returns the shifted value, or NULL if $array is empty or is not an array.

EXAMPLES

       Example #1

	      array_shift(3) example

	      <?php
	      $stack = array("orange", "banana", "apple", "raspberry");
	      $fruit = array_shift($stack);
	      print_r($stack);
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => banana
		  [1] => apple
		  [2] => raspberry
	      )

	       and orange will be assigned to $fruit.
