What best practices can be followed to avoid errors related to array types in PHP?

To avoid errors related to array types in PHP, it is important to properly check the type of the variable before performing array operations. This can be done using functions like `is_array()` or `gettype()`. Additionally, using type declarations in function parameters can help ensure that the correct type of data is passed to array-related functions.

// Check if a variable is an array before performing array operations
$myArray = [1, 2, 3];

if (is_array($myArray)) {
    // Perform array operations
    foreach ($myArray as $item) {
        echo $item . " ";
    }
} else {
    echo "Variable is not an array.";
}
