Program 1:
<?php // Declare an ArrayIterator $arrItr = new ArrayIterator(
array (
"a" => 4,
"b" => 2,
"g" => 8,
"d" => 6,
"e" => 1,
"f" => 9
)
); // Update the value at index 1 $arrItr ->offsetSet( "g" , "Geeks" );
// Print the updated ArrayObject print_r( $arrItr );
?> |
Output:
ArrayIterator Object ( [storage:ArrayIterator:private] => Array ( [a] => 4 [b] => 2 [g] => Geeks [d] => 6 [e] => 1 [f] => 9 ) )
Program 2:
<?php // Declare an ArrayIterator $arrItr = new ArrayIterator(
array (
"for" , "Geeks" , "Science" ,
"Geeks" , "Portal" , "Computer"
)
); // Update the value at index 1 $arrItr ->offsetSet(1, "GeeksforGeeks" );
// Print the updated ArrayObject print_r( $arrItr );
?> |
Output:
ArrayIterator Object ( [storage:ArrayIterator:private] => Array ( [0] => for [1] => GeeksforGeeks [2] => Science [3] => Geeks [4] => Portal [5] => Computer ) )
