In what scenarios would it be more efficient to negate the entire expression rather than individual functions like in_array in PHP?

In scenarios where you want to check if a value is not present in an array, it can be more efficient to negate the entire expression rather than using individual functions like in_array in PHP. This is because negating the expression can potentially save computation time by avoiding unnecessary function calls and comparisons. 

// Example code snippet to efficiently check if a value is not in an array
$value = 'apple';
$array = ['banana', 'orange', 'grape'];

if (!in_array($value, $array)) {
    echo "Value is not in the array";
} else {
    echo "Value is in the array";
}
