How to remove duplicates from a PHP array?

In PHP, you can use array_unique() A function for removing duplicate elements from an array. This function takes an array as a parameter and returns a new array containing only the unique elements from the original array. Here is an example:

$myArray = array('apple', 'orange', 'banana', 'orange', 'grape', 'apple');
$uniqueArray = array_unique($myArray);
print_r($uniqueArray);

Output:

Array
(
    [0] => apple
    [1] => orange
    [2] => banana
    [4] => grape
)

In the above example, the original array $myArray Contains some duplicate elements, for example 'orange' 和 'apple'By invoking array_unique() By applying the function, we obtain a new array. $uniqueArrayThis contains only the distinct elements from the original array.
