What potential issues can arise when PHP automatically chooses the data type for numbers?

When PHP automatically chooses the data type for numbers, it may lead to unexpected results or precision loss, especially when dealing with large numbers or floating-point calculations. To solve this issue, you can explicitly specify the data type for numbers using type casting or functions like `intval()` or `floatval()` to ensure the desired data type is used.

// Explicitly specify data type for numbers using type casting
$number = (int) $number;

// Using intval() function to convert to integer
$number = intval($number);

// Using floatval() function to convert to float
$number = floatval($number);
