How can one efficiently filter out specific values from an array in PHP without errors like unexpected values appearing?

When filtering out specific values from an array in PHP, it is important to use the array_filter function along with a custom callback function that specifies the condition for filtering. This ensures that only the desired values are retained in the filtered array without unexpected values appearing. By defining a clear filtering logic within the callback function, you can efficiently remove unwanted elements from the array. 

// Original array
$array = [1, 2, 3, 4, 5];

// Filter out values less than 3
$filteredArray = array_filter($array, function($value) {
    return $value >= 3;
});

print_r($filteredArray);
