What are some best practices for debugging PHP code that involves checking for arrays?

When debugging PHP code that involves checking for arrays, it is important to use the `is_array()` function to verify if a variable is an array before performing array-specific operations on it. This helps prevent errors such as trying to access array keys on a non-array variable, which can cause runtime errors. 

// Check if a variable is an array before performing array-specific operations
if (is_array($myArray)) {
    // Perform array operations here
    foreach ($myArray as $key => $value) {
        // Do something with each key-value pair
    }
} else {
    // Handle the case where $myArray is not an array
    echo "Variable is not an array";
}
