PHP array unique value

We may want to get a set of unique values from an array. For this we have to use function array_unique(). This will take an array as input and return an array with unique elements of the old array.

Here is our old array with some duplicate elements.

$old_array=array("Mango","Banana","Orange","Banana"); 
$new_array=array_unique($old_array); 


 Now our $new_array will contain values ("Mango","Banana","Orange")
