What potential issues can arise when using the %u specifier with negative numbers in PHP?

When using the %u specifier with negative numbers in PHP, potential issues can arise because the %u specifier expects an unsigned decimal number. To solve this issue, you can convert the negative number to its equivalent positive value before using the %u specifier. 

$negativeNumber = -10;
$positiveNumber = sprintf('%u', PHP_INT_MAX + $negativeNumber + 1);
echo $positiveNumber; // Output: 18446744073709551606
