What is the correct way to use the in_array() function in PHP to avoid errors related to data types?

When using the in_array() function in PHP, it's important to consider the data types of the values being compared. To avoid errors related to data types, you can use the third parameter of the in_array() function, which is a boolean flag for strict comparison. By setting this parameter to true, you ensure that both the value and the type are checked when determining if a value exists in an array.

$value = 5;
$array = [1, 2, 3, 4, "5"];

if (in_array($value, $array, true)) {
    echo "Value exists in the array.";
} else {
    echo "Value does not exist in the array.";
}
