I searched how to show only the de-duplicate elements from array, but failed.
Here is my solution:
<?php
function arrayUniqueElements($array)
{
return array_unique(array_diff_assoc($array1,array_unique($array1)));
};
?>
Example:
<?php
$arr1 = array('foo', 'bar', 'xyzzy', '&',
'xyzzy',
'baz', 'bat', '|', 'xyzzy', 'plugh',
'xyzzy', 'foobar', '|', 'plonk', 'xyzzy',
'apples', '&', 'xyzzy', 'oranges', 'xyzzy',
'pears','foobar');
$result=arrayUniqueElements($arr1);
print_r($result);exit;
?>
Output:
Array
(
[4] => xyzzy
[12] => |
[16] => &
[21] => foobar
)
