What are some best practices for efficiently removing duplicates from an array in PHP?
When removing duplicates from an array in PHP, one efficient approach is to use the `array_unique()` function. This function removes duplicate values from an array and returns a new array with unique values. By using `array_unique()`, you can easily eliminate duplicates without the need for complex loops or conditions.
// Sample array with duplicates
$array = [1, 2, 2, 3, 4, 4, 5];
// Remove duplicates using array_unique()
$uniqueArray = array_unique($array);
// Output the unique array
print_r($uniqueArray);
