Use the array_unique() function to remove the duplicates and sort - http://php.net/manual/en/function.array-unique.php
Following up with the array_values() function will remove the gaps in the array index - http://php.net/manual/en/function.array-values.php
// initialize array
var $array = array("b","c","c","a","d","e","a","d");
// remove duplicates and sort by string value
$array = array_unique($array, SORT_STRING);
// reindex array (numeric index will have gaps where the duplicates where removed)
$array = array_values($array);
// show results
print_r($array);
In Javascript/jQuery you can use the unique() and sort() methods
// initialize array
var array = ["b","c","c","a","d","e","a","d"];
// remove duplicate values
array.unique();
// sort remaining items
array.sort();
If you are sorting numbers in Javascript, you would need to pass a function, as the array is sorted lexicographically be default
array.sort(function(a,b){return a - b;});

in php you should use array_unique and sort for sorting array
$arr = array("b","c","c","a","d","e","a","d");
sort($arr);
print_r(array_unique($arr));
Comments
var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});

unique() is a Javascript function, PHP has a similar function array_unique(). Javascript syntax is array.unique() and PHP is array_unique($array).qustion asked:- How to display once elements of array ?. For example
var array = ["b","c","c","a","d","e","a","d"]
show => ["a","b","c","d","e"] ?
Any example ?
answer:- $arr = array("b","c","a","d","e","a","d");
$unique = array_unique($arr);//remove all duplicate values
sort($unique);//sort is done here
echo ""; print_r($unique );//shows show => ["a","b","c","d","e"]
