What are some best practices for working with unsigned data types in PHP to avoid potential errors or issues?

Working with unsigned data types in PHP can lead to potential errors or issues if not handled correctly, as PHP does not have built-in support for unsigned integers. To avoid problems, you can use bitwise operators to ensure that the values are treated as unsigned. Additionally, you can cast the values to the appropriate data type to enforce unsigned behavior. 

// Example of converting signed integer to unsigned integer using bitwise operators
$signedInt = -10;
$unsignedInt = $signedInt & 0xFFFFFFFF;
echo $unsignedInt;

// Example of casting signed integer to unsigned integer
$signedInt = -5;
$unsignedInt = (int) $signedInt;
echo $unsignedInt;
